[0001] SHIELDED COPPER OIL-BASED COMPOSITIONS
[0002] Throughout this application various publications are referenced. The disclosures of specific portions of these documents referred to are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this invention pertains. 5
[0003] This application claims priority of U.S. Provisional Application No. 63 / 606,909, filed December 6, 2023, the contents of which are hereby incorporated by reference.
[0004] TECHNICAL FIELD
[0005] The invention is most relevant to the technical field of agricultural, typically pesticide compositions. 10
[0006] The present invention relates to improved copper-shielding triazole compatibilizing agents, ingredients or additives that enable preparation of improved oil-based compositions comprising triazole fungicide in combination with copper-based ingredients exemplified by copper-based fungicidal compounds, as shielded copper fungicidal oil-based triazole fungicide compositions. The invention relates to improved non-aqueous, oil-based combinations comprising azole 15 (triazole) fungicide and copper shielding azole (triazole), compatibilizing agents with copperbased compounds most notably exemplified by copper-shielding or interfering compatibilizing agents which are often amine-type compounds having the ability to hinder or interfere with the interaction between the triazole and copper compounds so as avoid, or reduce the formation of copper-triazole complex thus ensuring a higher percentage of the triazole as “free” or 20 uncomplexed triazole, and thus maintaining its fungicidal efficacy. The more useful compatibilizing agents will not themselves form strong complexes with the typically high content of copper compounds, in the compositions, which might result in the agents themselves being unavailable to prevent the triazole-copper complexes.
[0007] Exemplary copper-shielding compatibilizing agents will thus have a greater affinity with 25 copper compounds than the azole or triazole compounds but lacking the tendency to be able to form full stable, strong and / or irreversible complexes with copper. Examples of such compatibilizing agent may include tertiary amines such as tributylamines, tripentyl amines, trihexyl amines, or tertiary amines wherein each substituent is a different alkyl or olefin, or for that matter only two of the substituents are the same but also primary and secondary organic 30 (alkyl, olefin, aryl etc.) amines wherein the alkyl groups are such that a copper-compatibilizing agent complex is unable to form or is hindered from forming. The suitable primary and secondary amines may include alkyl and dialkyl groups which make the compatibilizing agent sterically hindered thus avoiding stable, strong and / or irreversible copper-compatibilizing agent complex formation while still interfering the copper-azole complexation by having a greater affinity with copper than the triazole (azole) compound. These suitable primary and 5 secondary hydrocarbon amines may include alkyl or olefin amines wherein the hydrocarbon groups are long or fatty alkyl or olefin chains or be substituted with sterically hindered substituents that achieve the required hindrance to copper-compatibilizing agent complex formation.
[0008] These improved, copper shielding triazole compatibilizing agents allow for improved inventive 10 oil-based compositions of (compatibilized) free triazole fungicide combined with copper fungicide to be produced. The improved non-aqueous, oil-based compositions comprising azole (triazole) fungicide and copper fungicide are characterized by a higher proportion of free triazole fungicide and minimized formation of both triazole-copper complex, and copper- compatibilizing agent complex formation by inclusion of the triazole compatibilizing agents in 15 the non-aqueous, oil-based compositions.
[0009] The improved non-aqueous oil-based dispersion compositions are characterized in that the amount of dispersed copper-based compounds is in excess of the amount of copper shielding triazole compatibilizing agent.
[0010] One way of assessing the fungicidal availability of the triazole in the non-aqueous, oil-based 20 triazole compositions is by HPLC analysis, of the composition wherein the HPLC method can distinguish free triazole for example by resulting in a different retention time compared with bound or complexed triazole.
[0011] The present invention thus relates to non-aqueous fungicidal compositions comprising copperbased fungicidal compounds and triazole fungicidal wherein the triazole fungicide is one or 25 more of prothioconazole, cyproconazole, hexaconazole, tebuconazole, azaconazole, bromuconazole, diclobutrazol, difenoconazole, diniconazole, diniconazole- M, epoxiconazole, etaconazole, fenbuconazole, fluconazole, fluquinconazole, flusilazole, flutriafol, furconazole, furconazole-cis, imibenconazole, ipconazole, ipfentrifluconazole, mefentrifluconazole, metconazole, myclobutanil, penconazole, propiconazole, quinconazole, simeconazole, 30 tetraconazole, thiabendazole (triazole), triadimefon, triadimenol, triticonazole, uniconazole and uniconazole-P, their salts, esters, isomers and derivatives thereof, wherein triazole-copper complexation is minimized and the free triazole content in the composition is maintained as available for fungicidal efficacy while at the same time avoiding copper-based complexes that might deactivate the compatibilizing nature of the compatibilizing agent as well as reduce the amount of free fimgicidally active copper. In several typical embodiments of the invention the triazole is prothioconazole or tebuconazole. 5
[0012] The invention thus, relates to improved non-aqueous oil-based compositions, and aqueous dilutions thereof, comprising triazole fungicide, copper fungicide and improved triazole compatibilizing amine-type agent which are typically exemplified by tertiary amines such as tributylamine, mixed trialkyl amines, or sterically hindered primary or secondary organic amines wherein the substituents of the amine agent are such as to hinder or prevent the 10 formation of deactivating agent-copper complexes.
[0013] The compositions of the invention are characterized by preserved content of free triazole and free copper compounds due to the prevention of both significant triazole-copper complex formation as well as preventing formation of unwanted copper complexes formed by the interaction of the copper compound with the agent that prevents the triazole-copper complex 15 formation.
[0014] The advantages enabled by the inventive as non-aqueous compositions such as OD concentrates are often appreciated or realized once the concentrated compositions are diluted prior to fungicidal agricultural application and thus the invention is embodied both by the nonaqueous oil-based compositions as well as aqueous tank mix compositions prepared by diluting 20 or dispersing the inventive oil-based compositions in water.
[0015] The present invention provides improved oil-based, particularly non-aqueous oil concentrate (OD) compositions, of azole fungicides combined with a triazole compatibilizing agent typified by one or more organic amines such as alkylamine or arylamine represented by the structure A; 25 wherein: (i) R1is hydrogen, Cn alkyl, aryl, Cn alkenyl, Cn alkynyl or heterocyclic; R2is hydrogen, Cn alkyl, aryl, Cn alkenyl, Cn alkynyl or heterocyclic; and R3is hydrogen, Cn alkyl, aryl, Cn alkenyl, Cn alkynyl or heterocyclic; and
[0016] (ii) at least one of R1, R2, and R3is alkyl, aryl , alkenyl, alkynyl or heterocyclic,
[0017] (iii) when all of R1, R2, and R3are alkyl or alkenyl or alkynyl groups, then Cn is Ci-26, 5 commonly CJ-C24, or often C1-C22, sometimes C3-C18, such as butyl, pentyl, hexyl, and including alkyl fatty chains exemplified by, C12 or dodecyl (lauryl), saturated
[0018] Cis (stearyl) or unsaturated Cis (oleyl),
[0019] (iv) when the alkylamine (including olefinic amines alkenyl alkynyl), represented by the structure A is a primary or secondary amine then at least one of R1, R2, and R3are 10 aromatic, or alkyl or alkenyl or alkynyl groups, wherein Cn is Ce- 26, commonly Cs~
[0020] C24, often C8-C22 or C10-C22, such as alkyl fatty chains exemplified by, C12 or dodecyl (lauryl), saturated Cis (stearyl) or unsaturated Cis (oleyl).
[0021] While compounds represented by structure A above are exemplary or typical copper shielding triazole compatibilizing agents, it is important to emphasize that it is the ability of these 15 compatibilizing agents to interfere with both triazole-complex formation as well as avoiding any strong, stable or irreversible complexes of the compatibilizing agents themselves with the copper, that is more important than the specific chemical structure of the agent. Thus, while a particular molecule might fall within the definition of Structure A above, it will not be considered a suitable triazole compatibilizing agent if its inclusion in a composition of triazole 20 and copper-based compounds results in either lower free triazole content or less fiingicidally efficacious copper-based components.
[0022] In some embodiments, alkyl, which may be optionally substituted, denotes a linear or branched or cyclic hydrocarbon group comprising n carbon atoms.
[0023] In some embodiments, alkenyl, which may be optionally substituted, denotes a linear or 25 branched or cyclic hydrocarbon group comprising n carbon atoms and at least one double bond. In some embodiments, alkynyl which may be optionally substituted, denotes a linear or branched, hydrocarbon group comprising n carbon atoms and at least one triple bond.
[0024] In some embodiments, aryl, which may be optionally substituted, denotes to carbocyclic aromatic radicals having from 6 to 14 carbon atoms. 30
[0025] Tributylamine. The invention further relates to methods for preparing and using said compositions. The invention thus also relates to the preparation of oil dispersion (OD) typically concentrated compositions of azole (triazole), fungicides combined with copper fungicides in non-aqueous commonly immiscible solvent and / or carrier, comprising copper-shielding triazole compatibilizing agent (or “Copper Shielding Agent”), most notably organic amines exemplified by either Ci- 26 tertiary amines, such as tributylamine etc., or primary or secondary 5 organic amines, substituted with Ce- 26 organic groups having a structure that sterically hinders formation of strong complexes with the copper-based fungicidal compounds.
[0026] Thus, the present invention provides improved non-aqueous compositions, of azole fungicides in admixture or combination with copper compounds which inter alia prevent or avoid, the reduction of fungicidal (free) azole content by preventing and / or reducing azole interaction 10 with the copper compound, while simultaneously do not display significant content of stable, irreversible or strong copper-compatibilizing agent complexes that might reduce the amount of fungicidally available copper.
[0027] Clearly, aqueous diluted compositions prepared by diluting the improved non-aqueous compositions of the invention are equally within the scope of the invention particularly as the 15 advantageous preservation of free triazole in the non-aqueous oil-based compositions are realized when these oil-based compositions are applied as aqueous emulsions of free triazole and uncomplexed copper as agricultural pesticides.
[0028] The azole fungicides are typically the triazole fungicides such as one or more of, prothioconazole, cyproconazole, hexaconazole, tebuconazole, azaconazole, bromuconazole, 20 diclobutrazol, difenoconazole, diniconazole, diniconazole- M, epoxiconazole, etaconazole, fenbuconazole, fluconazole, fluquinconazole, flusilazole, flutriafol, furconazole, furconazole- cis, imibenconazole, ipconazole, ipfentrifluconazole, mefentrifluconazole, metconazole, myclobutanil, penconazole, propiconazole, quinconazole, simeconazole, tetraconazole, thiabendazole (triazole), triadimefon, triadimenol, triticonazole, uniconazole and uniconazole- 25 P, their salts, esters, isomers and derivatives thereof.
[0029] The present invention thus provides improved Oil Dispersion (OD) compositions comprising azole (triazole), fungicide such as prothioconazole or tebuconazole, copper compound and at least one copper-shielding triazole compatibilizing agent exemplified by tertiary amine such as tributylaminetributylamine, N-methyl-N-propyl-hexylamine, or sterically hindered primary or 30 secondary amines such as fatty alkyl amines or fatty dialkyl amines and optionally a further fungicide such as anilide / carboxamide fungicides, or strobilurin fungicides exemplified by fluxapyroxad, azoxystrobin or picoxystrobin, wherein the percentage of free azole content in the OD is not reduced by significant azole-copper complex formation with the copper and the compatibilizing efficacy of the agent is not compromised by significant complex formation with the copper compound.
[0030] The present invention thus provides improved Oil Dispersion (OD) compositions typically as 5 concentrates, comprising azole (triazole), fungicide compound such as prothioconazole or tebuconazole, and copper compound wherein the amount of free azole fungicide in the composition is maintained at levels significantly above 80%, and often above 90%, and in some cases above 95%, compared to the amount of the triazole used in the manufacture, during the process of manufacture and over periods of prolonged storage, measured by HPLC peak area 10 analysis at the same relative retention time (RT) as the azole fungicide used to formulate the composition. The free triazole content is maintained by the inclusion of triazole compatibilizing agent(s) as detailed herein. Significantly, the amount of the copper-shielding triazole compatibilizing agent is not reduced by complex interaction with the copper.
[0031] The invention provides improved Oil Dispersion (OD) compositions comprising azole 15 (triazole) fungicide compound and copper-based fungicide compound and copper-shielding triazole compatibilizing agent wherein the proportion of the free triazole is greater in the inventive compositions, compared to comparable compositions comprising the copper-based fungicide and the azole fungicide, formulated in the absence of the triazole compatibilizing agent wherein the proportion of the free triazole is an amount calculated when measured by a 20 method such as HPLC analysis of the peak area at the retention time associated with the free azole compound which is the azole fungicide that is used for formulating or preparing the composition.
[0032] In some embodiments, the invention provides improved Oil Dispersion (OD) compositions comprising azole (triazole) fungicide compound and copper-based fungicide compound and 25 copper-shielding triazole compatibilizing agent wherein the composition has a percent active content of azole fungicide (free triazole) as measured by HPLC analysis of the peak area at the retention time associated with the free azole compound, in the composition which is greater than the active content of azole fungicide as measured by HPLC in a composition comprising the same amounts of the same copper-based fungicide and the same azole fungicide without 30 copper-shielding triazole compatibilizing agent or with amines that form strong interactions with copper. In some embodiments, the composition comprises at least 70% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises at least 75% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises at least 80% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole . In some 5 embodiments, the composition comprises at least 85% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 80-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 85-99% of the amount of the azole fungicide which was used for 10 formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 90-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 95-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. 15
[0033] BACKGROUND
[0034] Copper-based fungicides are well-known but uses of copper-based fungicides are limited due to phytotoxicity to plant and toxicity to the user.
[0035] Combination of copper-based fungicide and azole fungicide are effective combinations in 20 controlling different (fungal), diseases in crops.
[0036] In compositions comprising copper-based fungicide and azole (triazole), fungicide, the amount of the fungicidally available azole fungicide referred to as free azole in presence of copperbased fungicide is reduced through azole-copper interaction and there is a need to find a method for preventing this phenomena. 25
[0037] Previously reported methods of addressing azole-copper interactions in pesticidal compositions would seem to have several drawbacks. It has been reportedly suggested that by chelating the copper compound with chelating agents such as EDTA the triazole-copper complex formation might be avoided.
[0038] However, inventors have found by experimental analysis, that in order to ensure that the 30 percentage content of free triazole is acceptable in Copper-Triazole fungicidal oil-based compositions using only chelating agent (EDTA), the entire amount of copper would have to be chelated requiring the addition / incorporation of greater than stoichiometric amounts of chelating EDTA. Besides being expensive and difficult to incorporate, the chelated copper is found to be so much more soluble when chelated that unacceptable phytotoxic effects are encountered when these previously suggested compositions are applied to crop plants. 5
[0039] Some researchers have suggested adding ingredients that were reportedly able to break up previously formed copper-azole complexes. These ”de-complexing” agents have been found to be only partially successful if at all, and typically, a significant amount of the azole fungicide is not free and / or precipitates indicating that these “decomplexants” are only partially successful in breaking up previously formed triazole-copper complexes. 10
[0040] More recently, exciting insights were gained when some researchers found that several compounds might prevent the formation of triazole-copper complexes by using inter alia, amines. However, when the content of the triazole compatibilizing agent is much less than the amount of the dispersed copper compound, or the copper is in molar excess of the agent, the particular structural attributes of the amine-type compatibilizing agent as detailed herein this 15 disclosure, becomes more important if they are to successfully compatibilize the triazole without being “neutralized” by deactivating agent-compatibilizing agent complex formation with the copper.
[0041] Several researchers have proposed solutions to the problem of azole-copper complexes which, according to their proponents, are only relevant to aqueous systems and compositions and are 20 understood to be inapplicable in non-aqueous and / or oil-based compositions such as Oily Dispersion OD concentrates.
[0042] There is thus an on-going need to address and / or prevent the reduction of fungicidally available azole due to interaction with copper compounds in non-aqueous systems exemplified by Oily Dispersion (OD) concentrates comprising both azole and copper fungicides. 25
[0043] Additionally, there is an on-going need to improve the dispersion quality and stability of Tankmixes prepared by diluting Oil Dispersions (OD) of triazole and suspended copper fungicides. SUMMARY OF THE INVENTION
[0044] The present invention provides a method for preparing oil-based compatibilized triazole fungicide comprising dissolving, a. triazole fungicide, and b. copper-shielding triazole compatibilizing agent, 5 in a non-aqueous and / or immiscible, solvent and / or carrier thus obtaining an oil-based triazole fungicide compatible with copper-based compounds wherein the copper-shielding triazole compatibilizing agent is characterised by both a greater chemical affinity for copper-based compounds than the triazole fungicide and minimal capacity to form stable, strong, or irreversible complexes with copper. 10
[0045] In common embodiments of the compositions enabled by compatibilizing the triazole fungicide, solid particulate copper-based compound is dispersed and suspended in the nonaqueous oil-based solution of copper-shielding triazole compatibilizing agent and triazole. These oil dispersion compositions are characterized in that greater than 80% of the triazole fungicide remains uncomplexed with copper as free triazole, even after periods of storage. 15
[0046] The present invention provides a method for preparing oil-based compatibilized triazole fungicide composition comprising dissolving, a. triazole fungicide, and b. copper-shielding triazole compatibilizing agent in a non-aqueous water-immiscible solvent and / or carrier comprising less than 5% water by 20 weight, and c. dispersing a copper-based fungicide compound in the oil-based triazole fungicide, to obtain a non-aqueous oil-based composition of compatibilized triazole fungicide and copperbased compound wherein the at least one copper-shielding triazole compatibilizing agent 25 comprises a tertiary amine or sterically hindered organic amine compound such that the copperbased fungicide compound is shielded from interacting with the triazole fungicide and wherein the copper-shielding triazole compatibilizing agent is characterized in that it does not form stable, strong, or irreversible complexes with the copper-based fungicide compound in the composition. 30
[0047] The present invention provides a method for preparing oil-based compatibilized triazole fungicide comprising dissolving, a. triazole fungicide, and b. copper-shielding triazole compatibilizing agent in a non-aqueous water- immiscible solvent and / or carrier comprising less than 5% water by weight, and c. dispersing a copper-based fungicide in the oil-based triazole fungicide, to obtain a non-aqueous oil-based composition of compatibilized triazole fungicide and copper- 5 based compound wherein the at least one copper-shielding triazole compatibilizing agent is a selected candidate compound that is capable or present in sufficient quantity in the Oil-Based composition of triazole fungicide and Copper-based fungicide to maintain at least 70 percent and advantageously greater than 80 percent of the triazole fungicide as free triazole in the tests outlined herein, in notable examples greater than 90% and greater than 95% of the triazole 10 remains free.
[0048] A general test for candidate selection protocol being exemplified by use of a general platform composition such as in the illustrative example detailed elsewhere or in general format below, but replacing the illustrated copper-shielding agent with one or several concentrations of the candidate compound and measuring the amount of free uncomplexed triazole (azole) by HPLC 15 after storage of the composition for two weeks at 54°C. A composition comprising greater than 70% of the azole as free triazole indicates that the candidate is a suitable copper-shielding triazole compatibilizing agent candidate for selection. A composition comprising greater than 80%, greater than 85%, greater than 90% or greater than 95% of the azole as free triazole indicates that the candidate is even more suitable copper-shielding triazole compatibilizing 20 agent candidate for selection.
[0049] Example of Non-Limiting Illustration Copper + triazole OD selection platform composition
[0050] The present invention provides a method for selecting a preferred copper-shielding triazole compatibilizing agent compound for use in compositions of the invention, from a group of 5 candidate amine compounds. A series of tests are performed with the objective to select a preferred copper-shielding triazole compatibilizing agent typically from a group of potential candidates. To be suitable, the inclusion of the tested triazole compatibilizing agent candidatetributylamine must be able to prevent the model triazole, prothioconazole from complexation with a model copper-based fungicide compound. 10
[0051] While many amine-based compounds have a greater affinity for copper compounds than triazole compounds, some theoretically shielding compound are not found to be useful because they form strong complexes with copper themselves and thus they are “consumed” or removed from the system in their compatibilizing role because of the large amount of “deactivating” copper in the system which is often included in very large amounts in typical copper-based 15 fungicidal compositions, and thus cannot perform their function to hinder triazole-copper complex formation.
[0052] The useful copper-shielding triazole compatibilizing agents are often organic amine compounds which have a greater affinity than the triazole for the cooper-based compounds in a triazole and copper oil-based composition, while simultaneously being unable to actually form strong complex structures with the copper.
[0053] In some embodiments useful copper-shielding triazole compatibilizing agents are tertiary organic amines with three nitrogen substituents typically having a carbon chain length (or cyclic structures) of Ci-26 . In some embodiments useful copper-shielding triazole 5 compatibilizing agents are primary or secondary organic amines with substituents that give characteristics to the shielding agent that prevent or hinder the formation of stable, irreversible, or strong copper-agent complexes with the copper components of the oily dispersion compositions. In some embodiments the primary or secondary organic amines which are useful copper-shielding triazole compatibilizing agents are those that have nitrogen substituents with 10 a carbon chain length (or cyclic structures) of Ce-26 .
[0054] In some embodiments the primary or secondary organic amines which are useful copper- shielding triazole compatibilizing agents are those amines that have nitrogen substituents such that they are fatty alkyl amines or similarly hindering unsubstituted groups.
[0055] While some simple or small, primary or secondary organic amines are unable to prevent 15 copper-triazole complex formation because of their strong interaction with the copper compounds, many large or otherwise sterically hindered amines are found to be useful at shielding copper compounds from complexing with co-formulated triazole fungicide compounds while at the same time are not “deactivated” or otherwise removed from the system by forming strong / stable or irreversible complexes with the copper. 20
[0056] In a method for selecting useful copper-shielding triazole compatibilizing agents a model composition might be used. An illustration of useful tests comparing the compatibilizing efficacy of a group of candidate compounds comprises preparing several comparable samples with the only difference being each being the identity of the candidate compound to be tested. While being in no way limited, a illustrative test Oily Dispersion composition for including 25 and then evaluating candidate compounds might contain 80 g / L of Prothioconazole, 70 g / L of Picoxystrobin and 300 g / L of Copper oxychloride in a non-aqueous carrier or vehicle suitable for agricultural compositions.
[0057] The compositions are prepared and analyses of each composition is performed after storage 12 hours at room temperature, as well as after storage at controlled conditions. The percentage of 30 free triazole is quantified and the results of Free triazole (Prothioconazole), and Percentage Recovery from the model OD Concentrates are calculated for example by comparing HPLC peak area and only compositions wherein the free triazole content in the composition remains equal to or greater than about 70% of the Triazole active ingredient introduced during preparation of the oil based OD composition, might be considered possible candidate copper- shielding triazole compatibilizing agents for further evaluation and selection.
[0058] 5
[0059] Importantly, the ability of a potential copper-shielding triazole compatibilizing agent compound to hinder triazole-copper complexes is not the only factor that will decide whether it will be of practical use, as clearly formulation considerations have to be considered. While two candidate copper-shielding triazole compatibilizing agents may have a similar level of shielding efficacy, one compound may be more soluble in the oily carrier or composition, one 10 of the candidates might be characterised by acidity / alkalinity that might destabilize one or more of the composition. It is reported for example that some amine compounds are corrosive or otherwise difficult to handle and these too will factor into the decision as to which candidate copper-shielding agent will be chosen.
[0060] Researchers skilled in formulation arts will of course be aware of many more considerations 15 that might make some candidate copper-shielding triazole compatibilizing agent compounds more suitable for a particular composition than others.
[0061] While a free triazole content in the composition remaining equal to or greater than about 75% of the Triazole active ingredient introduced during preparation of an oil based OD composition 20 after 12 hours may be a minimum acceptance criteria, in some embodiments the tests are conducted after storage for periods of time up to and including the proposed shelf life of the Oily Dispersion compositions and then again in diluted tank-mixes prepared by diluting the Oily Dispersion in aqueous medium such as, at a dilution of 1% in water, as would be prepared prior to pesticidal (fungicidal), application. 25
[0062] In some embodiments acceptable free triazole content in the inventive composition remains equal to or greater than about 75% of the Triazole active ingredient introduced during preparation of the oil based OD composition, during compounding, during storage, over the shelflife, and after dilution with water when preparing a Tank-mix of the OD prior to fungicidal 30 application.
[0063] In some embodiments acceptable free triazole content in the inventive composition remains equal to or greater than about 80% of the Triazole active ingredient introduced during preparation of the oil based OD composition, during compounding, during storage, over the shelflife, and after dilution with water when preparing a Tank-mix of the OD prior to fungicidal application.
[0064] In some embodiments the free triazole content in the composition remains equal to or greater than 85% of the triazole active ingredient introduced during preparation of the oil based OD 5 composition, during compounding, during storage over the shelf life, and after dilution with water when preparing a Tank-mix of the OD prior to fungicidal application.
[0065] In some embodiments the free triazole content in the composition remains equal to or greater than 90% of the Triazole active ingredient introduced during preparation of the oil based OD 10 composition, during compounding, during storage over the shelf life, and after dilution with water in preparing a Tank-mix of the OD prior to fungicidal application.
[0066] In some embodiments the free triazole content in the composition remains equal to or greater than 95% of the Triazole active ingredient introduced during preparation of the oil based OD 15 composition, during compounding, during storage over the shelf life, and after dilution with water in preparing a Tank-mix of the OD prior to fungicidal application.
[0067] In common composition embodiments the prevention of triazole -copper complex formation also prevents degradation of the physical quality attributes of the inventive oil-based 20 compositions.
[0068] The color of the oil-based compositions have been found be stable to changing color during storage, whereas comparable oil dispersion compositions absent the copper shielding triazole compatibilizing agent have been observed to change unacceptably when complex formation has occurred. In some illustrated examples the compositions changed from a turquoise color to 25 a dark brown color over storage for two weeks at 54°C.
[0069] Suspension stability and the size of suspended particles can also be advantages of the use of these copper-shielding agents.
[0070] The present invention provides oily, non-aqueous, compositions adapted to enable combination 30 with copper-based fungicides comprising,
[0071] A. a water immiscible carrier or solvent,
[0072] B. azole (triazole), fungicide, and
[0073] C. copper-shielding triazole compatibilizing agent, such as tributylamine. wherein the oily composition comprises less than 5% water and the copper-shielding triazole compatibilizing agent, prevents significant reduction of amount of fimgicidally available (free), triazole when the oily composition is in the presence of copper-based fungicide or comprises the copper compound.
[0074] 5 In many embodiments the composition is an oil dispersion concentrate adapted for dilution in aqueous media prior to fungicidal application.
[0075] In many embodiments the composition is an oil dispersion concentrate comprising a further pesticidal active ingredient, such as an additional fungicide. 10
[0076] Wherein, the copper-shielding triazole compatibilizing agent may have been one selected by a test based on a model composition as illustrated above, but the prior testing for selection is in no way a limit on which copper-shielding agent is used so long as it is able to maintain at least 70% of the triazole as free uncomplexed triazole. 15
[0077] Practitioners skilled in these fields after having this invention illustrated will often understand which compounds will be “good” copper shielding agents and which are likely to be deactivated in a composition through complexation with copper-based composition components or constituents. For these practitioner, the testing protocol above is perhaps superfluous, however this invention is designed to be simple even for the less skilled 20 researchers for whom the selection protocol may prove useful.
[0078] The present invention provides a non-aqueous, oil-based triazole fungicide comprising a combination of, a. azole (triazole), fungicide such as triazole fungicide, 25 b. copper-shielding triazole compatibilizing agent, and c. non-aqueous water-immiscible solvent and / or carrier, wherein the triazole fungicide and the copper-shielding triazole compatibilizing agent are dissolved in the non-aqueous solvent and / or carrier and the oil-based triazole fungicide is compatible with copper-based compounds. 30
[0079] Please note, the term copper-shielding triazole compatibilizing agent is sometimes herein referred to as copper-shielding agent, there is no intention to differentiate the compounds and they have the same meaning for the purposes of this invention. The present invention provides a non-aqueous agricultural, oil dispersion OD concentrate composition comprising, a. copper-based fungicide, b. azole (triazole) fungicide, c. copper-shielding agent, 5 d. water-immiscible, non-aqueous carrier or solvent, e. dispersant, and f. no more than 5% by weight of water,
[0080] In some embodiments, the dispersant, is of a type that is active only once concentrated oil 10 dispersion compositions of the invention are eventually diluted in water. These dispersants arecharacterized by requiring at least 1,000 parts of said water-immiscible non-aqueous carrier or solvent to dissolve one part of said dispersant and said SC-dispersant is not soluble in the OD concentrate composition. The utility of including dispersants with this characteristic in the oily dispersion concentrate is only fully realized once the oil dispersion concentrate is diluted 15 in an aqueous medium to improve the eventual aqueous dilute spray mix or tank-mix, and as such is counterintuitive. Surprisingly these oil-insoluble dispersants improve the dispersion quality of aqueous diluted compositions prepared by dispersing the OD concentrate in water prior to use but appear to have no role in the non-aqueous OD concentrate.
[0081] 20
[0082] The present invention provides diluted tank-mix comprising the non-aqueous, oil-based triazole fungicides that are disclosed here particularly agricultural, oil dispersion OD concentrate compositions dispersed and / or diluted in water.
[0083] 25 The present invention provides fungicidal oil-based (oily), compositions, notably OD concentrates comprising,
[0084] A. water-immiscible carrier or solvent,
[0085] B. azole (triazole), fungicide,
[0086] C . a copper-compatibilizing tertiary amine-type agent such as tributylaminetributylamine, 30 tri pentylamine, N-methyl-N-propyl -hexylamine, or tri hexylamine, a fatty alkyl amine or fatty dialkyl amine such as dodecyl (lauryl), stearyl or oleyl amines or otherwise sterically hindered primary or secondary amines,
[0087] D. suspended solid copper fungicide, and E. dispersant. wherein the oily composition comprises less than 5% water and the amine prevents any significant reduction of amount of fimgicidally available (free), azole in the presence of copperbased fungicide.
[0088] References to alkylamines, dialkylamines and trialkyl amines should be seen as referring 5 equally to tri-alkenyl amines and tri-alkynyl amines etc., the central feature being the ability of the compound to shield the copper-based component of the oil-based composition from complexing with the triazole component of the composition without forming a strong or stable and / or irreversible copper- agent complex.
[0089] 10 Tributylamine is exemplified as one of the copper-compatibilizing tertiary amines-type agent which prevents the formation of copper-azole complex and thus avoids the need to add an ingredient which acts as a decomplexation agent as was reported in the literature.
[0090] However, it is stressed that the useful tertiary amines need not have all three substituents being the same hydrocarbon group as it is the ability to function to prevent azole-copper complexes 15 forming and maintaining a high proportion of free azole in a non-aqueous dispersion composition, that will determine the suitability of any agent.
[0091] A dispersant that may be a useful optional ingredient in OD concentrates according to the invention is characterized by displaying minimal or negligible solubility in either the water 20 immiscible carrier or solvent or the non-aqueous OD composition, and yet will only act to improve the dispersion quality of aqueous compositions (Tank-mix), prepared by diluting the inventive composition in water.

[0093] (1) copper-based fungicide,

[0096] (4) tertiary amine compatibilizer agent (tributyl amine), wherein the oil-based composition is characterized by reduced triazole- copper complexation 30 analyzed by measuring the percentage of free azole remaining in the composition, when compared to OD compositions of copper-based fungicide and azole (triazole), fungicides absent the tertiary amine or compared with simple small primary or secondary amines that readily form strong complexes with copper. The level of free azole (triazole) content in the composition is usefully measured by HPLC analysis relative to a reference standard.

[0103] In some embodiments the free triazole content in the inventive composition remains equal to or greater than about 80% of the Triazole active ingredient introduced during preparation of the oil based OD composition, during compounding, during storage, over the shelf life, and after dilution with water when preparing a Tank-mix of the OD prior to fungicidal application. 20
[0104] In some embodiments the free triazole content in the composition remains equal to or greater than 85% of the Triazole active ingredient introduced during preparation of the oil based OD composition, during compounding, during storage over the shelf life, and after dilution with water when preparing a Tank-mix of the OD prior to fungicidal application.
[0105] In some embodiments the free triazole content in the composition remains equal to or greater 25 than 90% of the Triazole active ingredient introduced during preparation of the oil based OD composition, during compounding, during storage over the shelf life, and after dilution with water in preparing a Tank-mix of the OD prior to fungicidal application.
[0106] In some embodiments the free triazole content in the composition remains equal to or greater than 95% of the Triazole active ingredient introduced during preparation of the oil based OD 30 composition, during compounding, during storage over the shelf life, and after dilution with water in preparing a Tank-mix of the OD prior to fungicidal application.

[0142] In some exemplary embodiments the inventive triazole compatibilizing agent (copper- shielding additive), is a tertiary and / or sterically hindered alkylamine, aryl or olefinic amine ,and illustratively exemplified by tributylamine. The addition or inclusion of copper shielding agent during the preparation of non-aqueous, oil -based combinations of copper-based and azole (e.g., triazole) fungicides has astonishingly provided unexpectedly improved non-aqueous 20 compositions, where the improvement does not appear to be related to the usual activity of alkylamine in pesticidal formulations. The amount of free triazole available for fungicidal efficacy contained in the compositions is maintained both during compounding and over periods of storage up to shelf life, and the amount of complexed triazole fungicide is minimized, and thus the addition of compounds whose function might be described as de- 25 complexing agents is not needed, as the formation of these complexes has been avoided during the period when the composition is still a non- aqueous concentrate rather than reversed at the time of aqueous dilution.
[0143] This aforementioned prevention of azole-copper complex is particularly surprising where the copper-based fungicide is present as solid suspended insoluble particles, and the interaction 30 with triazoles might have a different character.
[0144] The invention provides a process for producing non-aqueous oil based compatibilized triazole fungicide by dissolving triazole fungicide in a non-aqueous solvent and / or carrier and combining with copper shielding triazole compatibilizing agents (aka copper shielding agents), most notably tertiary amines such as tributylamines or other amines which do not form strong copper-compatibilizing agent complexes. The compatibilized triazole fungicide obtained are useful to prepare improved inventive oil-based compositions of (compatibilized) triazole fungicide and copper fungicide. 5
[0145] The present invention provides a process for producing an oil based composition comprising a copper-based fungicide and azole (triazole), fungicide. A typical general process might comprise the following steps although clearly other process steps are contemplated.
[0146] In general, the process steps need not be in the order below, but for practical formulation reasons a particular order of steps may be more useful than others. 10
[0147] (a) dissolve the azole fungicide (e.g., prothioconazole, Tebuconazole etc.), in immiscible solvent(s) such as aromatic hydrocarbons and / or dialkyl decanamide);
[0148] (b) Add
[0149] (i) immiscible carrier such as Methyl Soyate;
[0150] (ii) dispersant 15
[0151] (iii) surfactant and optionally antifoam agent;
[0152] (c) add, a. copper shielding agent such as Tributylamine, b. copper fungicide e.g., Copper Oxychloride, and optionally c. a thickening agent exemplified by colloidal or fumed, silicon dioxide; 20
[0153] (d) homogenize & sieve.
[0154] In some embodiments the process continues with a packaging step, particularly where the packaging provides enhanced stability of the contained composition when stored at conditions exemplified by 54°C for 2 weeks.
[0155] 25
[0156] It should be clear that the order of the steps in the above general process for preparing one embodiment of the oil-based copper and azole (triazole) fungicide composition, is not always absolutely critical although in particular instances a particular order of steps may be easier to process than others, it may be that there is an advantage in compatibilizing the triazole before adding the copper compound depending on the other ingredients. This type of process 30 optimization including the choice of additional or alternative excipients is well within the capability of those ordinarily skilled in the pesticide formulation arts. In many embodiments the process for producing an oil based composition comprising a copperbased fungicide and azole (triazole), fungicide intrinsically includes the formation of compatibilized triazole fungicide as part of the preparation rather than as a separate process, without departing from the invention.
[0157] In many embodiments the process steps are completed by a packaging step wherein the oil 5 based composition is packaged in a container or package that ensures stability of the composition over the intended shelf life.
[0158] An example of a process for producing a specific 3-way example of the inventive composition may include the following steps, although clearly this is only illustrative and several of the ingredients other than those required for the inventive function can be changed for others as 10 described herein without departing from the general teaching provided.
[0159] Non-limiting illustrative compositions might include the following components. Persons skilled at formulating agricultural Oil Dispersions formulation will immediately see options for alternative inactive ingredients.
[0160] While the astonishing advantages of this invention are most apparent in compositions where 15 the amount of copper-based compound vastly exceeds the amount of copper-shielding triazole compatibilizing agent, and relatively small amounts of the agent can compatibilize an large excess of triazole fungicide, this invention is not dependent on the relative amounts (ratio), of the azole (triazole) and copper active pesticidal ingredients but rather the inclusion of relatively very small amounts of the copper-shielding amine-type ingredient which compatibilizes the 20 triazole to being in the same composition as the copper compound so that that least about 70%, and preferably considerably more of the azole active ingredient remains free and uncomplexed over storage and until applied at the point of use such that the invention relates to the prevention of deactivating triazole-copper complex and the maintenance of the great majority of Triazole as free, no matter how much copper and / or how much triazole is present within a very wide 25 range. Because the inclusion of the copper-shielding agent will compatibilize at least a portion of the triazole thus protecting at least some of the triazole which otherwise will disadvantageously complex with at least a portion of the copper.
[0161] As long as the oil-based composition comprises an amount of copper and an amount of Triazole (azole) in an immiscible solvent or carrier, the issue of formation of deactivating triazole- 30 copper complex is a problematic issue that is solved by the inventive use of surprisingly small amounts of copper-shielding triazole compatibilizing agent as herein defined. As alluded to above, one of the most surprising aspects of the invention is that surprisingly small amounts of copper-shielding triazole compatibilizing agent can shield very large amounts of copper from complex formation with triazoles while at the same time not being themselves neutralized or deactivated by the large excess of copper typically found in such compositions.
[0162] In order to ensure that these very small amounts of the amine type copper-shielding agents are 5 able to function as triazole compatibilizing agents the copper-shielding agent is selected primarily only from those compounds which do not form strong copper-agent type complexes, leaving the copper-shielding agent free to advantageously interact with the triazole (azole).
[0163] It is this sub-group of triazole compatibilizing agents that are herein termed “copper-shielding agents” in that they are both able to prevent formation of deactivating triazole-copper 10 complexes and at the same time are not depleted from the system (composition), by forming strong, stable and / or irreversible agent-copper type complexes.
[0164] Copper-shielding triazole compatibilizing agents are capable of compatibilizing many time their weight of triazole in oily dispersions comprising a great excess of copper.
[0165] In many oil dispersion concentrate composition embodiments according to the invention, it is 15 not uncommon for a composition comprising greater than 5% w / w triazole and greater than 20% w / w copper in immiscible carrier / solvent to be compatibilized by between about 0.3 and 1.8% w / w Copper-shielding triazole compatibilizing agents by weight based on the total weight of the composition.
[0166] The copper-shielding agents that are shown to be suitable are exemplified by tertiary organic 20 amines, aromatic amines, long-chain hydrocarbon substituted amines or fatty amines with chain lengths of at least Q or commonly greater than Cx and typically up to about C26 although more commonly having alkyl or olefin substituents with chain lengths of Cx-24 such as, C12 or Cis substituted amines as detailed herein elsewhere.
[0167] In some OD concentrate embodiments, the concentration of the copper-shielding triazole 25 compatibilizing agent as herein defined in the composition is no more than 10% by weight based on the total weight of the composition.
[0168] In some OD concentrate embodiments, the concentration of the copper-shielding triazole compatibilizing agent in the composition is between 0.1% and 8% ±10% (about 8%), more typically 0.3% to 5%± 10%, and particularly noted between 0.5 - 2.5% ±10% by weight based 30 on the total weight of the composition. In some OD concentrate embodiments, the concentration of the copper-shielding triazole compatibilizing agent in the composition is between about 0.5 - 1.8% ±10% (about 1.8%), by weight based on the total weight of the composition.
[0169] In some OD concentrate embodiments, the concentration of the copper-shielding triazole compatibilizing agent in the composition is between about 0.75 - 1.4% ±10% (about 1.4%), by 5 weight based on the total weight of the composition.
[0170] In some concentrate composition embodiments of the invention the concentration of the tributylamine in the composition is between 0.5% and 1.6% ±10%. In some exemplified OD concentrate embodiments, the concentration of the tributylamine in the composition is 0.75%±10% and in some other embodiments the concentration of the tributylamine in the 10 composition is 1.2% ±10%.
[0171] In some embodiments the concentration of the copper-shielding triazole compatibilizing agent in the composition is between about 0.5 - 1.2% ±10% (about 1.2%), by weight based on the total weight of the composition. In some embodiments the copper-shielding triazole compatibilizing agent in the composition is either tertiary amine such as tributylamine or fatty 15 (long chain) amine or otherwise sterically hindered amine unable, to form copper-agent strong, stable or irreversible complexes in the composition.
[0172] The non-limiting examples of compositions we use to illustrate the invention, include an optional additional active ingredient as well as illustrative non-active formulation ingredients, for the purposes of the non-limiting illustrations, we exemplify compositions comprising more 20 than one type of surfactant and more than type of Immiscible carrier or solvent, to reflect some common formulation practices but by no means suggesting that there is significance of these non-active ingredient choices to the operation of the invention other than optimization.
[0173] However, as the invention relates only to the interaction of triazole (azole) compounds with copper compounds in a carrier and the inventive inclusion of a copper-shielding agent (triazole 25 compatibilizing), the other (non-pesticidally active), ingredients of the illustrative compositions can be referred to by their formulation functions together with exemplified examples of each. Persons skilled in these formulation art will immediately be aware of alternative ingredients that will perform the same formulation function, such alternative ingredients are no departure from this invention as the identity of these excipient non-active 30 ingredients are not necessarily critical to the working of the invention of preventing the complex formation. Clearly however, persons skilled in the formulation arts will chose these non-active compounds to optimize the characteristics of the composition (triazole compatibilizing), but both optimized and non-optimized compositions are within the scope of the invention so long as Copper-based compound, free Azole (triazole) compound and copper shielding (triazole compatibilizing), agents are contained in an oil-based composition, such as in an Oil Dispersion concentrate, or 5 diluted ready-to-spray mixes (tank-mix) prepared by diluting the OD concentrate .
[0174] Illustrated below is a platform composition detailing both the essential and optional components of a large number of OD concentrate embodiments of the invention. The content of the Copper, Triazole and copper-shielding triazole compatibilizing agent are exemplified (non-limiting), numerically as they are the central components together with the non-aqueous 10 immiscible carrier or solvent. The other ingredients are included by their function as the relative amounts in such a composition is well within the skills of any Oil Dispersion formulation practitioner and the invention is in no way dependent on the exact numerical content of these other ingredient components.
[0175] Non-Limiting Illustration of OD Copper 300 triazole 80 Oil Dispersion OD concentrate
[0176] In the platform illustrated general composition above it can be seen that the immiscible carrier / solvent, surfactant, and emulsifier can be mixtures of these types of components as is often found in Oil Dispersion compositions. In some embodiments the Copper Shielding 5 Triazole Compatibilizing Agent comprises no more than 2% w / w of the weight of the total composition, and often between about 0.3% and 1.8% w / w.
[0177] The Copper-based compound is exemplified by cupric acetate, cupric chloride, cupric chlorate, cupric formate, cupric hexafluoro silicate, cupric nitrate, cupric chromate, copper sulfate pentahydrate, Bordeaux mixture, copper hydroxide, cuprous oxide, copper oxychloride, copper 10 oxychloride sulfate (COCS), tribasic copper sulfate such as cupric sulfate, tri -cupric hydroxide, hemihydrate, complexed or chelated copper compounds, and any combination thereof.
[0178] When the copper-based fungicidal compound comprises chelated copper the chelated copper comprises no more than 5% by weight of the total copper in the composition.
[0179] Illustrative examples of the additional active ingredients can include though not limited to 5 strobilurin fungicides, benzamide fungicide, morpholines, Qil fungicide, SDHI and any combination thereof. Strobilurin fungicide may include but is not limited to azoxystrobin, coumoxystrobin, enoxastrobin, flufenoxystrobin, picoxystrobin, pyraoxystrobin, mandestrobin, pyraclostrobin, pyrametostrobin, triclopyricarb, kresoxim-methyl, trifloxystrobin, dimoxystrobin, fenaminstrobin, metominostrobin, orysastrobin, 10 metyltetraprole and fluoxastrobin. SDHI may include but is not limited to penthiopyrad, boscalid, flutolanil, fluxapyroxad, inpyrfluxam , fluopyram, fluindapyr, benzovindiflupyr, bixafen and pydiflumetofen. Qil fungicide may include but is not limited to cyazofamid, amisulbrom and fenpicoxamid. Morpholines may include but is not limited to aldimorph, fenpropimorph, tridemorph, dodemorph, spiroxamine, piperalin, fenpropidin. 15
[0180] Immiscible carrier / solvent can be illustrated by hydrocarbons, Cio, aromatics (Solvesso 150), heavy aromatic naphthalene (Solvesso 200), methylated soybean oil, N,N-dimethyl decanamide.
[0181] Surfactant can be illustrated by ) ABA poly hydroxyester-PEG-poly hydroxyester copolymers (Zephrym PD2206 block copolymer), tristyrylphenol ethoxylated(Soprophor BSU), 20 polyoxyethylene (20) sorbitan monolaurate (Tween 24-lq-(ap), oxirane, monobutyl ether (Atlas G-5002L-lq-cq), alkyl end-capped polyethylene oxide-polypropylene block copolymer, Benzenesulfonic acid, Cio-i3-(linear)alkyl derivatives, calcium salt, (Rhodacal 60 / BE).
[0182] An oil dispersion concentrated composition comprising Prothioconazole 80g / L, Fluxapyroxad 50g / L, Copper Oxychloride 300 g / L and tributylamine 6 g / L in a mixture of Hydrocarbons, 25 Cio, aromatics (Solvesso 150), Methylated Soybean oil and N,N-Dimethyl Decanamide, was found to have greater than 98.5% of the Prothioconazole as free Prothioconazole after storage at 54°C for two weeks when analyzed by HPLC peak area comparison with prothioconazole reference standard. This oil dispersion concentrated composition also contained ABA poly hydroxyester-PEG-poly hydroxyester copolymers (Zephrym® PD2206 -block copolymer), 30 tristyrylphenol ethoxylated (Soprophor® BSU), Polyoxyethylene (20) sorbitan monolaurate (Tween 24-lq-(ap)), butyl polyethylene oxide-polypropylene block copolymer (Atlas G-50021- Iq-(cq)), benzenesulfonic acid, Cio-i3-(linear) alkyl derivatives, calcium salt, (Rhodacal® 60 / BE) and Distilled Tall Oil (DTO), (Altapyne M28-B), inventors do not believe these ingredients effect the ability of the tributylamine to compatibilize the prothioconazole to maintain free prothioconazole and shield the copper. Similarly, the oil dispersion concentrated composition contained fumed silica (Cab-o-Sil M5) as a thickener and Polydimethylsiloxanes 5 as an antifoam agent, inventors do not believe these ingredients are intrinsic to the effect of compatibilizing the prothioconazole to remain as free prothioconazole or the copper-shielding effect, although formulation optimization by skilled formulators by careful selection is envisaged.
[0183] The Copper Shielding (Triazole Compatibilizing) Agent has been herein defined elsewhere 10 though some illustrative examples include tertiary organic amines such as tributylamine or primary and secondary amines that may include hydrocarbon amines which may include alkyl or olefin amines wherein the hydrocarbon groups are long or fatty alkyl or olefin chains or be substituted with sterically hindered substituents that achieve the required hindrance to coppercopper shielding agent complex formation. 15
[0184] Similarly, amine type compounds substituted by one or more aromatic groups are often suitable candidates as copper shielding agents, and a simple test as outlined elsewhere in this disclosure will reveal the suitability of the candidate for a specific Oil Dispersion composition. As detailed elsewhere a simple test employing a model Oil Dispersion platform is a suitable vehicle for comparing potential candidates for selection of the optimum copper-shielding agent. It may 20 well be that the selection is based on the minimum content of the agent that is required for triazole compatibilization, although often this is not the only criterion for selection which will include many formulation quality aspects.
[0185] In some embodiments the invention provides oil-based compositions of triazole and copper fungicides and a copper shielding amine such as tributylamine optionally comprising an 25 additional pesticide (fungicide), other than a triazole or copper compound, the compositions characterized by comprising less than 25% of the triazole in a complex with the copper, and preferably significantly less. In most preferred embodiments less than 5% of the triazole included when compounding the composition is measured as triazole-copper complex or nonfree triazole.

[0194] Inventors have surprisingly found that oil-based (OD) compositions of triazole (azole) fungicides together with copper fungicides can be formulated without significant triazolecopper complex formation by inclusion of copper-shielding agents, including tertiary amines exemplified by tributylamine or long -chain, fatty or sterically hindered amines. This is an 5 important improvement because often triazole-copper complexes precipitate and / or the triazole fungicide that is complexed with copper is no longer available to act as a fungicide. Importantly though, inventors have found that it is possible to prevent or avoid triazole-copper complex formation by inclusion of no more than about 10% by weight of the composition of the amine- type copper-shielding agents so long as the copper-shielding agent, which compatibilize 10 triazoles is carefully selected such that a minimum of strong, stable and / or irreversible agent- copper complex is formed.
[0195] In typical embodiments less than about 3% w / w, often less than about 2.5% w / w, of the copper- shielding agent is enough to entirely avoid significant copper-triazole deactivating complex formation, even when the triazole content is much greater than this. In some OD concentrate 15 embodiments of the invention no more than 2% w / w by weight based on the total weight of the composition.
[0196] While it is conceivable that when an amine-type triazole compatibilizing agent compound which does indeed form strong agent-copper complexes is in great molar excess as compared to the copper content in the composition, exemplified by situations where the entire continuous 20 phase of the dispersion is the amine-type agent, then the choice of compound for compatibilizing the triazole might conceivably be not be important.
[0197] But, as previously mentioned this is not the case when, the content of the triazole compatibilizer in the composition is no more than 10%, and particularly when the agent comprises greater than 0.1% and less than 3% w / w by weight based on the total weight of the composition, or at 25 a ratio to copper of no more than 1:2.5 or particularly when the ratio of agent to copper is less than 1:8 then the choice of the copper-shielding triazole compatibilizing agent is extremely important to avoid strong interactions of the agent with copper that might deplete the amount of amine available to compatibilize the triazole to such an excess of copper.
[0198] Thus, the inventors identify a group of copper-shielding triazole compatibilizing agent or 30 ingredient or additive, most notably tertiary amines such as tributylamine, or otherwise substituted amines that are unable to form strong, stable and / or irreversible copper- agent complexes, such as sterically hindered or amines substituted with long chain alkyl or olefin groups such as fatty amines, which when combined with triazole fungicides provide compatibilized triazole fungicide compound at very low concentrations in oily dispersion compositions while not being themselves deactivated as compatibilizers by forming strong copper-agent complexes. 5
[0199] The copper-shielding agents together with triazoles form compatibilized triazole fungicide compound which can be formulated as non-aqueous, oil-based compositions together with copper fungicides wherein the compositions are characterized by less than significant levels of triazole-copper complex formation and highly preserved content of free triazole fungicide, as compared to comparable compositions absent the triazole compatibilizing agent. In 10 compositions of the invention the amount of free triazole compared to the amount of triazole included when compounding the composition is exemplified by at least 70% and preferably, considerably in excess of 75% free triazole preserved.
[0200] Thus, in some embodiments, the composition comprises at least 70% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole . In some 15 embodiments, the composition comprises at least 75% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises at least 80% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises at least 85% of the amount of the azole fungicide 20 which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 80-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 85-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the 25 composition comprises 90-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole. In some embodiments, the composition comprises 95-99% of the amount of the azole fungicide which was used for formulating or preparing the composition as free triazole.
[0201] The copper shielding agent which in several embodiments are tertiary amines exemplified by 30 tributylamines, in the inventive oil -based (OD) composition at a contents of less than 10% by weight, prevents the formation of triazole-copper complex and maintains a high proportion of free triazole, available for fungicidal efficacy, mediated by being selected for being unable to form strong, stable or irreversible copper-agent complexes .
[0202] In typical embodiments the selected copper shielding agent is such that it is capable of compatibilizing at least three times the amount of triazole by weight.
[0203] In noted embodiments when carefully selected, a copper-shielding agent content of between 5 0.3% and 2% w / w weight based on the total weight of the composition is sufficient to compatibilize the great majority or even all the triazole in a composition comprising greater than 5% triazole, commonly between about 0.5% and about 1.5% is sufficient.
[0204] In an illustrative embodiment, a non-aqueous oil dispersion concentrate composition, (density about 1.2) comprising about 25% dispersed copper oxychloride (about 300g / L) and about 7% 10 dissolved prothioconazole (about 80 g / L) by weight in immiscible carrier / solvent was compatibilized by no more than about 0.5% w / w (about 6 g / L), tributyl amine. When this composition is analyzed after storage at 54°C for two weeks, greater than 98.5% of the triazole used for compounding the composition is found to remain as free prothioconazole measured by comparing the HPLC peak area against a free prothioconazole reference standard at the 15 same relative retention time (RRT). Significantly, in the above experiment, greater than 99% of the copper as oxychloride is measured in the composition after storage at 54°C for two weeks, indicating that the copper had not formed stable, irreversible or strong copper- compatibilizing agent complexes. Additionally, the composition is color stable and remains a turquoise suspension indicative of the uncomplexed copper compound. 20
[0205] Inventors foresee that particular organic amines having specified characteristics can be as useful as tertiary amines to act as copper-shielding triazole compatibilizing agents. In principal it appears that a suitable agent is one that has both a greater affinity to copper than the triazole, while simultaneously being unable to form strong complexes with the large excess of copper typically found in these oil dispersion compositions. Thus, sterically hindered amine based 25 compounds perhaps with aromatic substituents or long -chain (C8-22) fatty amines may have the characteristics of both shielding the copper from forming complexes with triazole compounds and yet not removed from the system by forming compatibilizing agent-copper complexes.
[0206] Many of the disclosed copper-shielding agents useful as triazole compatibilizing agents are required to be dissolved in (hydrophobic), non-aqueous water-immiscible solvent and / or 30 carrier and also several of the disclosed copper-shielding agents useful as triazole compatibilizing agents are long chain or fatty amines, thus, in some embodiments the copper- shielding triazole compatibilizing agents are amine type compounds which have a low Hydrophilic / Hydrophobic balance such as below HLB=9 or below HLB = 6.
[0207] In some embodiments, the copper-shielding triazole compatibilizing agents are amine type compounds with long chain hydrocarbon substituents, such as fatty alkyl or olefin chains, characterized by an HLB equal or less than 9. 5
[0208] In some embodiments, the copper-shielding triazole compatibilizing agents are organic amine type compounds with hydrocarbon substituents characterized by an HLB equal or less than 6.
[0209] Thus, for a particular Oil Dispersion composition of triazole and copper compounds a test may 10 be conducted to compare two similar compounds of different HLB values, to see which is more suitable. For example, taking ethoxylated tallow amines as candidate tertiary amines it is noticed that ethoxylated tallow amines having two moles of ethylene oxide groups per mole has a calculated HLB of 5 whereas ethoxylated tallow amines having eight moles of ethylene oxide groups per mole has a calculated HLB of 11. A useful comparative test will easily 15 determine which of these compounds is most suitable for inclusion in an oil dispersion of triazole and copper compound though it is envisaged that perhaps both are equally useful depending on the details of the composition ingredients. Conceivably this simple test will show that neither or both of these compounds is useful because of factors unconnected to the HLB value. 20
[0210] The term “triazole compatibilizing agent” does not imply that the activity or mechanism by which these agents achieve their effect is necessarily by affecting some chemical or physical change in the triazole compound itself (although it is conceivable that it might), but rather the term triazole compatibilizing agent is simply an acknowledgment that the effect of inclusion of these agents in a composition comprising a triazole fungicide results in the triazole in the 25 composition being protected from complex formation when the composition is combined with compounds such as copper-based fungicides. Thus, the corresponding term “compatibilized triazole” does not necessarily imply that a comparison between a solution of triazole compound in the same solvent absent the “triazole compatibilizing agent”, would reveal any measurable difference in the triazole compound other than the property that the solution of triazole 30 fungicide is to some extent compatible with a copper-based fungicide, as regards the loss of free triazole by complex formation when that solution is combined with the copper compound.
[0211] Inventors have found that the inclusion of copper-shielding agents such as tertiary amines, such as tributylamine, or tertiary amines with different alkyl or olefin substituents, in oil-based compositions of triazole and copper fungicides, promotes multiple improvements and 5 advantages in the characteristics of compositions of triazole and copper fungicides. These aforementioned advantages might include the function of tributylamine in preventing reduction of Cu2+ions to copper and assisting in achieving stable and high quality oil-based OD dispersions, in addition to their other surprising function as compatibilizing agents for triazole fungicides. 10
[0212] It has been observed that oil dispersion compositions of triazole fungicide and copper oxychloride with copper shielding triazole compatibilizing agent are additionally stable to unwanted physical degradation such that they are for example, stable and do not appreciably change color over storage while a comparable composition absent the copper-shielding agent changes from a turquoise suspension to dark brown during storage. Such color changes may 15 perhaps be a direct result of azole-copper complexes in non-compatibilized compositions.
[0213] While inventors highlight the triazole compatibilizing activity of the tertiary amines (e.g. tributylamine, N,N,N-butyl, pentyl, hexylamine etc.), as well as the other specifically useful amines as defined elsewhere in this disclosure, the use of the term “triazole compatibilizing agent” should in no way be viewed as limiting, but rather as a convenient way of labelling the 20 copper-shielding ingredient and no limitation is intended or implied that would limit the invention to any specific level of content other than being less than 10% by weight of the composition, or use simply based on the level of compatibilizing ability separate from other important functions and advantages obtained by their inclusion.
[0214] The invention relates to the prevention of triazole -copper complex formation rather than (or in 25 addition to), the breaking or decomplexation of a complex that had already formed. Inventors have found that the prevention of triazole -copper formation with minimal amounts of tertiary amines, exemplified by tributylamine and the other similarly useful compounds defined elsewhere in this disclosure, is a much more useful solution the identified problem than either the use of de-complexing agents, or the use of chelating agents to pre-chelate the copper 30 compound. In all experiments performed to date, no more than 2.5% of the copper-shielding triazole compatibilizing agents were needed to maintain greater than 80 percent of free triazole in an oil dispersion even in combination with over 20% copper based compounds and often significantly more than 80% such as more than 95% or more than 98% w / w.
[0215] In experiments comparing various candidates as triazole compatibilizing agent ingredients or components, and the minimum content of each required to maintain high a proportion of the triazole as “free triazole” in the OD compositions, inventors found the optimized characteristics 5 of the most useful of these agents as detailed herein. The free azole was tested after comparing compositions having the same general composition with the tested candidate ingredient being the only variant and as measured by HPLC recovery by absorbance peak area comparison, at the RRT of the triazole used, . For illustrative purposes the triazole fungicide chosen is any of prothioconazole, tebuconazole, difenoconazole, with prothioconazole being a useful model 10 triazole.
[0216] As an example, in the samples containing 0.5 % w / w and 1.25 % w / w tributylamine of the candidates tested in the experiments, the recovery results were able to be higher than 98%.

A noted composition is an Oily Dispersion concentrate. While the compositions of the invention are decidedly oil-based, it is often necessary to add the SC-dispersants in the form of aqueous solutions or colloids, for ease of processing and homogeneity. The small amounts of water introduced into the compositions of 20 the invention that are associated with the commercially available aqueous-composition dispersants in no way detracts from their being oil-based compositions and being included within the contemplated scope of this invention, with the proviso that the SC-dispersants are insoluble to any discernable degree in the liquid components of the oil-based composition and the water content of the oil -based composition comprises no more than 5% water by weight. 25
[0256] A surprising feature of the copper triazole Oil Dispersion composition of the invention is the ability of a minimal amount of the selected copper-shielding agent is sufficient to compatibilize much larger amounts of triazole in the presence of much larger amounts of copper. The invention is focused on copper-shielding agents capable of compatibilizing amounts of triazole in the presence of much larger amounts of copper than the agent. 30

[0286] As with all figures and numbers, ratios are intended to be preceded by “about” meaning, where relevant ± 10% unless the context is clearly otherwise. Where the number or figure is related to a limit, such as “not more than” or “not less than”, then the figure is understood to be within the normal understanding of rounding up or down.

Wherein the triazole fungicide is dissolved in the immiscible carrier or solvent and the copper-based compound is 25 dispersed immiscible carrier or solvent.
[0293] In some embodiments, the concentration of the copper-based fungicide (typified by copper oxychloride), is up to or about 50%, more typically up to or about 35% and particularly up to or about 25% by weight based on the total weight of the composition. In some embodiments, the concentration of the copper-based fungicide is about 10% by weight based on the total 30 weight of the composition and in noted examples 25%±10% (22.5 - 27.5%). In some embodiments, the concentration of the copper-based fungicide in the composition is between about 100 and 650 g / L (90 - 715 g / L), typically 300 g / L ±10% (270 - 330 g / L).
[0294] In some embodiments, the copper-based fungicide is Copper Oxychloride in which metallic copper represents approximately 60% by weight thus, in some embodiments, the concentration of the metallic copper (as component of non-metallic copper compounds) in the formulation 5 comprising the copper-based fungicide is up to 30% ±10%, more typically up to 20% ±10%, and particularly up to 15% ±10%, by weight based on the total weight of the composition. In some embodiments the oil-based compositions comprise between 10 g / L to 400 g / L±10%, metallic copper. In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is between about 50 g / L to about 300 g / L. 10 In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is 180 g / L ±10%.
[0295] In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is about 1-25% by weight based on the total weight of the formulation.

In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is about 10% by weight based on the 20 total weight of the formulation. In some exemplified embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is 14% ±10%, by weight based on the total weight of the formulation which translates to approximately 23% Copper Oxychloride. Similar calculations are immediately apparent when the copper fungicidal compound has a different metallic copper content by adjusting the above example. 25
[0296] In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is up to 25% by weight based on the total weight of the formulation. In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is 10% by weight based on the total weight of the formulation. “Metallic copper” in the above discussion regarding copper compounds exemplified by copper 30 oxychloride, refers to the portion of the copper compound which is the copper ion e.g., Cu2+ cation, or element and does not imply that the copper is in the form of metallic particles unless considering actual copper metal.
[0297] In some embodiments, the concentration of the metallic copper in the formulation comprising the copper-based fungicide is between about 100 and about 500 g / L, typically, 300 g / L ±10%.
[0298] In some embodiments, the concentration of the copper-based fungicide in the composition is 5 between about 15% to about 45% by weight based on the total weight of the composition. In some embodiments, the concentration of the copper-based fungicide in the composition is between about 20% to about 35% by weight based on the total weight of the composition. In some embodiments, the concentration of the copper-based fungicide in the composition is between about 25% to about 30% by weight based on the total weight of the composition. In 10 some embodiments, the concentration of the copper-based fungicide in the composition is 28.8% ±10% by weight based on the total weight of the composition.
[0299] In some embodiments, the copper-based fungicide is copper sulfate. In some embodiments, the copper-based fungicide is copper oxychloride. In some embodiments, the copper-based fungicide is copper hydroxide. In some embodiments, the copper-based fungicide is Bordeaux 15 mixture. In some embodiments, the copper-based fungicide is comprised at least in part of a copper complex or chelate for example Copper(II) bis-alginate, Copper(II) glycinate, Cu(II)- EDTA and similar copper-based compounds. While water soluble copper compounds can be included, as mentioned above, the proportion of the copper content in chelated or soluble complexed form is perhaps better limited to a small proportion to minimize copper mediated 20 phytotoxicity.
[0300] In some embodiments, the concentration of dispersant, in the composition is between about 0.01% to 15% ±10% by weight based on the total weight of the composition. In some embodiments, the concentration of the dispersants in the composition is between 0.01% to 10% ±10% by weight based on the total weight of the composition. In some embodiments, 25 concentration of the dispersant in the composition is between 0.1% to 8% ±10% by weight based on the total weight of the composition.
[0301] It should be clear that the addition of further processing aids and additives, e.g., surfactants, antifoam, thickeners etc., appropriate for oil-based compositions are definitely contemplated by the inventors and decidedly within the scope of the inventive compositions. 30 In some OD concentrate embodiments, the concentration of the tributylamine in the composition is between 0. 1% and 8% ±10%, more typically 0.3%to 5%± 10%, and particularly noted between 0.4 - 1.7% ±10% by weight based on the total weight of the composition. In some concentrate composition embodiments of the invention the concentration of the tributylamine in the composition is between 0.5% and 1.6% ±10%.In some exemplified OD 5 concentrate embodiments the concentration of the tributylamine in the composition is 0. 5%±10% - 0.75%±10% (about 0.5% - about 0.75%) and in others the concentration of the tributylamine in the composition is 1.2% ±10% - 1.5% ±10% (about 1.2% - about 1.5%).
[0302] Inventors note that while a range of concentrations of the tributylamine component in a particular OD composition of a copper-based fungicide and triazole fungicide is useful across 10 the whole range, often formulation considerations seemingly unconnected with the inventive compatibilizing function will determine the optimal tributylamine concentration for that particular OD concentrate.
[0303] In some cases, a formulator might wish to control the pH of an aqueous composition obtained by diluting or dispersing the non-aqueous OD concentrate in water, perhaps to provide the most 15 chemically or physically stable environment for one or more of the components of the inventive composition or the quality of the whole composition. As can now clearly be understood, a range of tributylamine concentrations that are equally useful in compatibilizing the azole (triazole) fungicide provides the scope for a formulator to adjust the tributylamine content to provide both the azole compatibilization required for the OD and tank mix obtained therefrom, as well 20 as the optimal pH of the tank mix obtained by diluting / dispersing the OD concentrate in water.
[0304] In all events when wishing to determine the acceptable triazole compatibilizing agent identity and percentage content in a non-aqueous Oily composition of a copper-based fungicide and triazole fungicide that has not been specifically exemplified herein.
[0305] The methodology used in the experimental section as herein disclosed above or later in this 25 disclosure should also be seen as a general method to determine whether a particular candidate for use as a triazole compatibilization agent and the percentage of that candidate content that is suitable for that composition.
[0306] In essence a very simple protocol for assessing the acceptability of a formulated composition as is exemplified later herein. 30 The test to assess a candidate as a triazole compatibilizing agent, can be performed with the objective to confirm that the inclusion of the candidate triazole compatibilizing agent, is able to prevent significant triazole complexation with copper, or alternatively to show that a candidate compound component is unable to adequately avoid the triazole-copper complexation. 5
[0307] A candidate compound that is able or sufficiently present in the Oil-Based composition of triazole fungicide and Copper-based fungicide to maintain at least 80 percent of the triazole fungicide as free triazole in the above outlined tests, is to be seen as a more acceptable triazole compatibilizing agent / ingredient / additive .
[0308] The percent active content of azole fungicide of the triazole fungicide as free triazole is usefully 10 measured by HPLC analysis comparing the peak area at the retention time associated with the amount of triazole fungicide compound, used to formulate the composition..
[0309] To establish the optimal triazole compatibilizing agent compound or the optimal content, prepare samples with the only difference being test component / ingredient variation.
[0310] The analyses may be performed after storage 12 hours at room temperature. The analysis is 15 performed after the composition is stored for a period not less than two weeks at 54°C to select even more optimal copper-shielding triazole compatibilizing agent.
[0311] In some embodiments, the triazole compatibilizing agent candidate is alkylamine, olefin amine, or aromatic amine so long as the agent has a higher affinity for copper than the triazole 20 compound but is unable itself, to form strong stable (irreversible) complexes with copper.

[0338] In some noted embodiments, the compositions comprise one or more additional fungicide which is soluble in the immiscible solvents / carriers of the composition and typically characterized by poor water solubility, having a typical solubility of less than about 25mg / L in 20 water at 20°C. Typical instances of the additional fungicide are anilide or carboxamide fungicides, exemplified by fluxapyroxad and strobilurin fungicides exemplified by azoxy strobin and picoxystrobin. the concentration of the additional fungicide in the composition is generally between 1% to 10% ±10% by weight based on the total weight of the composition.

That being said, in each of the above embodiments the water immiscible carrier and / or solvent can usefully be selected from any one of, or a mixture of more than one, selected from the group of aromatic hydrocarbons (e.g. toluene, o-, m-, p-xylene, ethylbenzene, isopropylbenzene, tert-butylbenzene, naphthalenes, mono- or polyalkyl-substituted naphthalenes), paraffins (e.g. octane, nonane, decane, undecane, dodecane, tridecane, tetradecane, pentadecane, hexadecane, hepta-decane, octa-decane, nona-decane, eicosane, heneicosane, docosane, tricosane, tetracosane, pentacosane, and branched chain isomers thereof), petroleum, ketones (e.g. acetophenone, cyclohexanone), vegetable oil (e.g. olive oil, kapok oil, castor oil, papaya oil, camellia oil, palm oil, sesame oil, com oil, rice bran oil, peanut 5 oil, cotton seed oil, soybean oil, rapeseed oil, linseed oil, tung oil, sunflower oil, safflower oil, tall oil), alkyl ester of vegetable oils, (e.g. rapeseed oil methyl ester or rapeseed oil ethyl ester, rapeseed oil propyl esters, rapeseed oil butyl esters, tall oil fatty acids esters etc...), diesel, mineral oil, fatty acid amides (e.g. C1-C3 amines, alkylamines or alkanolamines with Q - Cis carboxylic acids), dimethylamide of fatty acid, N,N- dimethyl alkylamide (N,N-dimethyl 10 decanamide, N,N- dimethyl octanamide, N, N-dimethyl dodecanamide, N,N-dialkyl alkanamide), N-alkyl alkanamide, fatty acids, tall oil fatty acids, alkyl esters of fatty acids (e.g. C1-C4 monohydric alcohol esters of Cx to C22 fatty acids such as methyl oleate, ethyl oleate), modified vegetable oils and combinations thereof.
[0433] 15 To be clear, compositions that include destabilizing ingredients that damage, reverse or otherwise function to lessen or remove some if not all of the advantages attributable to the invention, are not favored. However, inventors can foresee specific formulation constraints which may require a formulator to include these less than optimal ingredients, and thus inventors point out that simply adding a less favored ingredient to the inventive oil-based 20 composition will not exclude that composition from the scope of the invention and may be within the scope of protection being sought. This is especially (though not exclusively), the case where the less-favored ingredient, has been added in an amount that does not adversely affect the invention.
[0434] 25 Oil-based compositions comprising all the inventive components that have been “sabotaged” or compromised by the inclusion of known, or predictably damaging ingredients so that all the inventive advantages have been “lost”, are to be considered as outside the scope of the invention and not any indication that some of the claimed compositions are “non-working”.
[0435] Inventors consider this disclosure as being directed to skilled formulators who would make 30 reasonable efforts to prepare useful compositions, a composition that ignored the basic principles of the art of formulation are not preferred embodiments, though the composition may still be encompassed by the invention in certain circumstances for example where a “damaging” ingredient is included and then removed or safened by reversing its unwanted effect to regain the free azole, perhaps in an attempt to circumvent these teachings.

[0701] A composition and / or combination according to the invention is suitable for the control of pests 25 that are encountered in horticulture, agriculture, and forestry. The compositions are active against normally sensitive and resistant pest species and during all or individual stages of development. Prior to use, a composition comprising a copper-based fungicide and azole fungicide according to the invention is diluted to provide ready-for-application composition comprising between 0.001 and 10 w / v% of the copper-based fungicide. If required, 30 agriculturally acceptable carriers such as a sticking agent is added to the ready-for-application composition. A composition according to the invention is often diluted 2-5000 times, typically about 200 times, often about 100 times, to contain between about 0.0001 and 10 % (w / v) of the copperbased fungicide, prior to contacting a plant, plant part or soil (area or locus) with the composition.
[0702] To control agricultural pests, the invention provides a use of a composition comprising a 5 copper-based fungicide and azole fungicide according to the invention for the protection of a plant, or a part of a plant, or locus (e.g., soil) against a pathogen. In order to achieve this effect, said plant or plant part, or a soil, is contacted with said composition, including any ready-for- application composition.
[0703] Said compositions are used, for example, to control soybean rust, powdery mildew and downy 10 mildew infections on food / feed crops, including tree fruits, vegetable crops, field crops, grapes, ornamental plants, and sod farms.

A further common part of a plant that is coated with a composition according to the invention, or with a dilution thereof, is leaf. 5 A further commonly encountered part of a plant that is coated with a composition according to the invention, or with a dilution thereof, is a fruit, typically a post-harvest fruit such as, for example, a citrus fruit such as orange, mandarin and lime, a pome fruit such as apple and pear, a stone fruit such as almond, apricot, cherry, damson, nectarine, tomato, watermelon, a tropical fruit such as banana, mango, lychee and tangerine. A noted fruit is a citrus fruit, such as orange 10 and / or a tropical fruit such as banana. In addition, when lists are provided, the list is to be considered as a disclosure of each member in the list, independently.Each embodiment disclosed herein is contemplated as being applicable to each of the other disclosed embodiments. Thus, all combinations of the various elements described herein are within the scope of the invention. In addition, the elements recited in the composition embodiments can 15 be used in the process, method and use embodiments described herein and vice versa.
[0707] This invention will be better understood by reference to the Experimental Details which follow, but those skilled in the art will readily appreciate that the specific experiments detailed are only illustrative of the invention as described more fully in the claims which follow thereafter.
[0708] The invention is illustrated by the following examples without limiting it thereby. 20
[0709] Copper Oxychloride 300 / Fluxapiroxad50 / Prothioconazole 80 OD
[0710] Density about 1.2
[0711] Exemplified Non-Limiting Illustration of a Method of Preparation
[0712] In a tank with agitation, add Solvesso 150, Dimethyl Decanamide, Prothioconazole (triazole), 5 and Fluxapyroxad (additional a.i.), heat at e.g., 70°C, keeping under agitation (e.g., 300 - 400 rpm) until complete Al solubilization. Then, turn off the heating and under stirring add: ATLAS G-5002L-LQ-(CQ), Tristyrylphenol ethoxylate, Tween, Antifoam, Dodecylbenzene sulfonic acid calcium salt, Distilled Tall Oil (DTO) - (Altapyne M28-B), Methyl Soyate, and lignosulfonate. Cool down until getting temperature less than 35°C, add Copper compound and silica (Cab-o-Sil M5), increasing the agitation between 1000 to 1500 rpm e.g., using agitator type Cowles. After finishing, filter the product through a 100 mesh sieve before packaging into closed container. 5
[0713] Stability studies:
[0714] A series of tests were performed with the objective to confirm that the inclusion of the exemplified copper shielding triazole compatibilizing agent, tributylamine is able to prevent the exemplified triazole, prothioconazole complexation with the copper by comparing the inventive composition with an equivalent composition absent the copper shielding triazole 10 compatibilizing agent. As can clearly be seen in the above non-limiting illustrative example, when the non aqueous oil dispersion composition comprises the Copper Shielding Triazole Compatibilizing Agent, tributyl amine (Inventive), greater than 99% of the Prothioconazole remains free after two weeks storage at 54°C. In addition, it can be seen that the compatibilized inventive Oil 5 Dispersion Concentrate remains a Flowable turquoise suspension.
[0715] In contrast when the comparative composition is absent the Copper Shielding Triazole Compatibilizer (Comparative), the composition changes to a dark brown color and the Free Prothioconazole content is reduced to 62% after two weeks stored at 54°C. Even when comparing the compositions after only two weeks at room temperature, it is apparent that the 10 inventive OD composition maintains a greater Free Prothioconazole content.
[0716] While the pesticidal efficacy advantages of this invention has been linked to the numerical % content of Free triazole available for maintaining fungicidal activity in non-aqueous oil-based compositions of triazole and Copper-based compounds, clearly the physical quality of such compositions is an important aspect of any commercial product and as can be seen, 15 compositions in which there have been significant loss of free triazole through formation of azole-copper complex will also suffer from a qualitative degradation. In the above example the uncompatibilized oil-based composition changes from a Turquoise color to dark brown after two weeks stored at 54°C. This type of degradation of the appearance of the composition would be unacceptable even if efficacy was not so clearly affected. 20
