Description

[0001] The present invention relates to an adjuvant composition, in particular for agrochemicals, which has the property of modifying the working liquid of a pesticide and multidirectionally activating its action, a method for its production and its use.

[0002] Numerous adjuvant compositions are known in the prior art. The requirements of today's crop protection market, coupled with food safety and environmental protection policies, are the driving force for the development of new, more advanced multifunctional adjuvants for pesticides that simultaneously enable: a higher biological efficacy of the pesticide and efficient methods of production, distribution and use under field conditions, for example due to low viscosity and stability in the spray liquid.

[0003] US 5356861 discloses a homogenous mixture for use with a herbicide containing, but not limited to, water, a surfactant, and ammonium sulfate. The adjuvant mixture described therein is intended as an additive to a spray tank containing water and glyphosate herbicide, ready for use in the field. It has further been disclosed that a surfactant from the group of alkyl polysaccharides allows for compatible combination with ammonium sulfate in the adjuvant composition and then with glyphosate in the spray tank.

[0004] US10701932 B2 discloses a composition containing dicamba and a drift control agent, which is prepared in a spray tank immediately before use in the field. The drift control agent contains at least one fatty alcohol and, in addition to the fatty alcohol, may also contain a fatty alcohol alkoxide. In addition, the disclosed composition may contain polydimethylsiloxane as a defoamer. Furthermore, the surfactant includes, but is not limited to, a nonionic surfactant, including ethoxylated fatty acid esters and alkyl polyglycosides. This composition in the spray tank can interact with other pesticides (including glyphosate or glufosinate).

[0005] US Pat. No. 8,877,682 B2 discloses dry, flowable adjuvant compositions comprising a polysaccharide and a salt composition, wherein the salt is diammonium hydrogen phosphate, sodium carbonate, or a combination thereof, and the polysaccharide is a derivatized guar gum. It further discloses that an aqueous composition can be prepared which further comprises a dispersant, such as, for example, a polyethoxylated fatty alcohol, a polypropoxylated fatty alcohol, or a polyethoxylated sorbitan fatty acid ester, and, in addition, a complexing agent, such as ammonium sulfate and a defoamer. The document also describes the use of the adjuvant composition described therein for preparing an aqueous working solution containing a herbicidally active substance (e.g., glyphosate) in a spray tank immediately prior to use.

[0006] US2016 / 0227768 A1 discloses an aqueous adjuvant concentrate containing: a potassium salt, at least one surfactant and hydroxypropyl tamarind gum dissolved therein. In addition, the possibility of preparing a spray liquid containing the adjuvant composition as described therein and at least one suitable herbicide is disclosed. This group of beneficial surfactants includes, but is not limited to, polyethoxylated alcohols having 8 to 24 carbon atoms, polyethoxylated dehydrated sorbitan fatty acid esters and alkyl polyglycosides. The herbicidal spray liquid formed in the sprayer tank from the disclosed adjuvant concentrate described therein may further contain conventional additives such as thickeners, buffers, fillers and defoamers. According to the present disclosure, the herbicide present in the working liquid may be glyphosate or glufosinate ammonium, and as described, the working liquid itself exhibits optimal properties in controlling the drift of the droplets and retaining them on the sprayed surface.

[0007] US20210127665 A1 discloses a spray liquid composition typically formed in a sprayer tank, the spray liquid composition containing water, an agricultural chemical composition (such as a pesticide), at least one oil adjuvant emulsion that reduces the droplet drift of the composition according to the document, and at least one adjuvant that reduces spray drift. According to the cited literature, the oil emulsion may contain, but is not limited to: one or more surfactants selected from the group consisting of alkoxylated alcohols, dimethyl polysiloxanes, alkyl polyglycosides, polyoxyethylene sorbitan monolaurate, etc., acting as an emulsifier. A silicone-based defoamer and, for example, ammonium sulfate and another water regulating component may be further added to the composition. An agricultural chemical composition is also disclosed, which may include at least one pesticide, fertilizer, and a combination thereof. Examples of herbicides include, but are not limited to, glyphosate and glufosinate.

[0008] US 9332763 B2 discloses an aqueous adjuvant concentrate capable of reducing droplet drift during spray applications and a method for preparing the concentrate. One variant of the aqueous adjuvant concentrate comprises, but is not limited to, ammonium sulfate, anionic alkyl polysaccharide esters, and hydroxypropyl guar gum. The disclosed composition is stable and can be used as an additive to a spray liquid containing a suitable plant protection agent, such as, but not limited to, glyphosate or glufosinate. In addition to the components listed above, other conventional additives may be present in the herbicide spray liquid solution prepared in the manner disclosed therein.

[0009] EP 2341778 B1 discloses a liquid concentrated herbicide composition containing glyphosate as an active ingredient and a mixture of multifunctional modifying and activating adjuvants incorporated into the formulation. The composition contains a mixture of adjuvants, preferably comprising at least one surfactant, such as an alkyl polyglycoside, ammonium sulfate, a carboxylic acid, and another substance. In addition, the specification also mentions triethanolamine in combination with glycerol as an acceptable component of the composition according to the literature, which is intended to ensure its homogeneity. In addition, the examples mention the presence of A further component in the form of SB 2032, which acts as a defoamer and, according to the instructions, contains a modified fatty alcohol.

[0010] Adjuvant compositions disclosed in the art are compositions containing various combinations of components typically intended to prepare spray liquids for short-term use in a spray tank. If combined in any other manner according to the knowledge available to those skilled in the art, they will not form stable adjuvant compositions, or even stable pesticide formulations, and therefore the functions of these components cannot be fully utilized. Therefore, the prior art lacks specifications for ready-to-use adjuvants (marketable products) that combine so many interacting components with different functions important for the effectiveness of the pesticide. The prior art does not disclose solutions for combining active pesticide substances with similarly large amounts of components that synergistically support their effects (ready-to-use, commercial pesticide formulations) in a lasting and stable manner. This is directly due to the aforementioned inability to combine some chemically different components in a stable and ready-to-use composition, and due to the unfavorable functional properties of the resulting formulations, including the instability of the adjuvant / pesticide formulation / composition, the excessive viscosity of such compositions, and the low stability of the spray liquid after such formulations are added to the spray tank (caused by precipitation or separation of the components). The prior art further shows that the methods used to prepare adjuvant compositions are generally standard methods known in the art (mainly mixing with water in the sprayer tank immediately before the agrochemical treatment) which do not allow the formation of stable formulations of components (finished products, marketable products) that were previously unavailable in the prior art while maintaining the functional properties of the target adjuvant compositions.

[0011] The object of the present invention is to develop an adjuvant composition of components of a high chemical diversity with specific usefulness in plant protection, the combination of which in a single formulation will ensure high utility values for the entire composition, and further provide it with improved viscosity parameters and complete solubility in water, thereby allowing such compositions to be used under field conditions. However, a primary goal is to develop a composition that will comprehensively address many of the problems that occur when using plant protection products, which are only selectively met by adjuvant compositions known in the art. Another object of the present invention is to develop a method that will allow all desired components to be combined and to prepare a stable composition, wherein none of these components precipitate from the composition and the components of the composition will not separate. Wherein this desired stability is applicable to one or more ready-to-use, marketable products that are about to become multifunctional adjuvants and one or more readily available marketable pesticides (two separate product categories). Regardless of the product category, this adjuvant composition can be produced on an industrial scale, will ensure higher pesticide activity, while reducing the possibility of the dosage used, which will translate into reducing the chemical footprint in food production, and reducing the pollution of agriculture and the surrounding agricultural environment.

[0012] The present invention relates to an adjuvant composition, in particular an adjuvant composition for activating agrochemicals, comprising water, ammonium sulfate, hydroxypropyl guar gum, at least one surfactant, and a silicone defoamer, characterized in that the adjuvant composition comprises oleyl alcohol and the surfactant is selected from the group consisting of at least one alkoxylated fatty alcohol, an alkyl polyglycoside, polyethoxylated sorbitan monolaurate, and combinations thereof, and in that the ratios of water, ammonium sulfate, hydroxypropyl guar gum, surfactant, silicone defoamer, and oleyl alcohol, expressed in wt.% relative to the total adjuvant composition, are 35 to 47 wt.%, 25 to 34 wt.%, 1.5 to 2 wt.%, 17 to 22 wt.%, 0.03 to 0.07 wt.%, and 4.5 to 5.5 wt.%.

[0023] Preferably, stage 1 is carried out at a temperature ranging from 20°C to 35°C and a stirring speed ranging from 50 rpm to 200 rpm for a time ranging from 20 minutes to 40 minutes.

[0031] Preferably, the silicone antifoaming agent is octamethylcyclotetrasiloxane.

[0032] A further subject of the present invention is the use of the adjuvant composition according to the invention for preparing a mixture with an agrochemically active substance, wherein the mixture is selected from the group consisting of stable, ready-to-use mixtures incorporated into a formulation of one or more agrochemically active substances and mixtures to be added immediately before spraying into a sprayer tank carrying the one or more agrochemically active substances.

[0033] Preferably, the agrochemical active substance is selected from the group consisting of: glyphosate isopropylamine salt, glyphosate ammonium salt, glyphosate potassium salt, glyphosate trimethylsulfonium salt, and glufosinate ammonium as a mixture of D isomer and L isomer and the L form alone; acetyl-CoA carboxylase inhibitors: quizalofop-p-ethyl, cypermethrin, pinoxaden, etc.; ALS inhibitors: imazamox, cypermethrin, thiabendazole, etc.; photosystem I inhibitors: diquat, etc., photosystem II inhibitors: betadine, bentazon, etc.; carotenoid biosynthesis inhibitors: mesotrione, etc.; and synthetic auxins: 2,4-D, MCPA, dicamba, etc., as well as other foliar herbicides, fungicides, insecticides and growth regulators, and mixtures thereof.

[0034] Preferably, the agrochemically active substance is selected from the group comprising glyphosate isopropylamine salt, glyphosate ammonium salt, glyphosate potassium salt, glyphosate trimethylsulfonium salt and glufosinate ammonium (in both D-isomer and L-isomer forms).

[0035] Preferably, the amount of agrochemically active substance in the mixture is in the range of 120 to 450 g per 1 1, preferably 120 to 360 g / 1, more preferably 120 to 300 g / 1, most preferably 120 to 200 g / 1.

[0036] The research of adjuvant composition according to the present invention comprises many stages. First, the work of introducing hydroxypropyl guar gum (HPG) was carried out. This hydroxypropyl guar gum is a kind of surfactant (in this case, Atlox AL-2575LQ of Croda) that prevents spray droplets from drifting into a mixture containing water, ammonium sulfate and a group of surfactants from an alkyl polyglycoside with a carbon chain length of C8-C10. HPG does not disperse completely and quickly after being introduced into the above-mentioned mixture, forming dense particles, which requires long-term mixing to obtain a homogeneous mixture. After obtaining the homogeneous mixture, HPG settles to the bottom of the composition after a few minutes. It is also difficult to add silicone defoamers, such as octamethylcyclotetrasiloxane (e.g., SAG1599). Despite prolonged mixing and attempts to be dispersed in the mixture, the material floats to the surface over time and adheres to the wall of the container where mixing occurs, especially to the wall of the plastic container. It should be emphasized that due to the strong foaming of the spray liquid caused by the alkyl polyglycoside surfactant, it is necessary to add a defoamer. Exemplary compositions of such unstable compositions are given in Table 1. These are Compositions 1 and 2, which additionally contain triethanolamine (TEA), which has a buffering effect on the pH of the spray liquid, bringing it above 7, which is important for complete dissolution of the sulfonylurea herbicide with which the composition will be combined in the sprayer tank. Subsequent studies unexpectedly showed that it is possible to introduce an HPG anti-drift agent and an octamethylcyclotetrasiloxane antifoam into a mixture of water, ammonium sulfate and an alkyl polyglycoside and obtain a stable composition, and that this can be significantly facilitated by the initial mixing of HPG and octamethylcyclotetrasiloxane in oleyl alcohol (using the commercial product Rofanol 90 / 95V containing this alcohol) and then adding it to the remaining adjuvant components.

[0037] Therefore, during the course of research, a method according to the present invention was developed, which proved to be effective in preparing the adjuvant compositions according to the present invention. This method is carried out in three stages and involves dissolving ammonium sulfate and an alkyl polyglycoside in water (mixture A), followed by preparing mixture B by mixing oleyl alcohol with HPG and the silicone antifoaming agent octamethylcyclotetrasiloxane. The third stage involves adding mixture B to mixture A while mixing. Examples of compositions obtained in this manner are compositions 3 and 4 (Table 1), in which triethanolamine (TEA) is additionally present as a buffer. In aging tests, these compositions remained homogeneous for at least 14 days at temperatures of 0°C, 20°C, and 54°C. Unfortunately, the aforementioned compositions 3 and 4, although they did not separate, were characterized by excessively high viscosities, which posed significant obstacles to their production and practical use (e.g., difficulty filling and emptying containers, difficulty transporting them in pipelines, etc.). Furthermore, these compositions proved unstable when used at low concentrations (after dilution to the appropriate use concentration), as they precipitated from the spray liquid in the form of water-insoluble flocs (fine gel structures). This behavior completely excludes their usefulness as adjuvants for supporting the action of plant protection products, since it leads to clogging of spray equipment and thus makes spray treatment impossible.

[0039]

[0040] *Determined using a Brookfield DV2T viscometer at 20 rpm and 20°C

[0041] Further studies of the compositions according to the invention and their preparation methods have shown that replacing a portion of the alkyl polyglycoside nonionic surfactants without ethoxy groups with polyethoxylated sorbitan monolaurate (e.g., Tween 20) or nonionic surfactants containing ethoxylated or propoxylated C16-18 alcohols or mixtures thereof (e.g., the product Rokanol RZ4P11) allows the viscosity to be reduced to the limits accepted for the use of pesticides in industrial and agricultural practice (less than 3000 mPa·s at 20°C). Furthermore, it allows the components of the adjuvant composition to be precipitated from the spray liquid in the form of water-insoluble flocs (fine gel structures), especially when used in low concentrations. The compositions of these adjuvant compositions according to the invention are given in Table 2 below - these are compositions 5 to 8. These compositions are also obtained by the three-stage process according to the invention. In a first stage, mixture A is prepared by mixing appropriate amounts of water, ammonium sulfate, alkyl polyglycoside and polyethoxylated sorbitan monolaurate or appropriate polyethoxylated C16-18 alcohols, polypropoxylated C16-18 alcohols or mixtures thereof, mixture B is then prepared as described above, and in a third stage, mixture B is added to mixture A while mixing. The compositions obtained according to the invention are characterized by a viscosity acceptable in industrial and agricultural practice, by maintaining homogeneity after 14 days of storage in an aging test at temperatures of 0° C., 20° C. and 54° C., and by not precipitating in the spray liquid even after use at low doses or high dilutions (they are stable).

[0042] In addition to increasing the effectiveness of the pesticide, the advantages of the adjuvant composition according to the invention obtained by the method according to the invention are its stability and acceptable viscosity during production and packaging, as well as in agricultural practice. Thanks to the method according to the invention, not only can components that previously could not coexist in a single adjuvant composition be combined, but also compositions according to the invention that simultaneously perform many important functions from a plant protection perspective can be obtained. The components used therein limit the negative impact of calcium and magnesium ions contained in the water used to prepare the spray liquid on the effectiveness of the pesticide, limit the drift of small droplets of the spray liquid with wind during application, significantly increase the retention of droplets and enable better wetting of the sprayed surface, limit the rapid drying of droplets from the surface, relax the cuticle (the main barrier to the penetration of pesticides into cells), and enhance the active uptake and transport of active substances into cells. Due to this, the composition according to the invention has a multi-directional effect, which significantly facilitates processing, increases its effectiveness, and most importantly, allows the dosage of the pesticide used to be reduced, thereby reducing its potential harmful effects on the environment and agricultural products. In addition, the improved viscosity parameters mentioned above make it possible to use the composition according to the invention under field conditions using conventional spray equipment. At the same time, it should be mentioned that the adjuvant composition is suitable for use with agrochemical active substances, especially herbicides, both due to the possibility of permanent incorporation into pesticide formulations that are stable for at least three years, and also as a stand-alone, ready-to-use product that can be mixed with the plant protection product in the spray tank under field conditions immediately before use. In addition, field tests have shown that it improves the effectiveness of agrochemical active substances, regardless of whether the adjuvant composition according to the invention is added to the spray tank just before use or is part of a ready-to-use, stable pesticide formulation.

[0043] The invention is illustrated by the following examples.

[0173] In addition, herbicide formulations containing the compositions according to the present invention are also prepared. These formulations contain the isopropylamine salt of glyphosate (hereinafter referred to as glyphosate) or glufosinate ammonium (hereinafter referred to as glufosinate ammonium) as the herbicidal active agent and the adjuvant composition according to the present invention. It is also permitted to use other glyphosate salts, such as ammonium salts, potassium salts and trimethylsulfonium salts, as well as mixtures of glyphosate and glufosinate ammonium (which are in the form of both the D isomer and the L isomer of glufosinate ammonium and the L-glufosinate form itself), mixtures of glyphosate with 2,4-D, MCPA and dicamba, and mixtures of glyphosate with glufosinate ammonium and 2,4-D, MCPA and dicamba.

[0174] Attempts to incorporate adjuvant composition 4 into glyphosate and adjuvant composition 3 into glufosinate ammonium (in both cases, these adjuvants did not contain the nonionic surfactant Tween 20) were unsuccessful (cf. Formulations 1 and 2 - Table 3). Homogeneous herbicide formulations were indeed obtained, but, like the introduced adjuvant compositions, these formulations were characterized by excessively high viscosities that were unacceptable in industrial and agricultural practice (glyphosate formulations) and a tendency to precipitate in the spray liquid. These problems were completely overcome by incorporating adjuvant composition 6 according to the invention into the glyphosate and glufosinate ammonium of adjuvant composition 5 according to the invention. The resulting herbicide formulations 3 and 4, having the composition of the components specified in Table 3, were characterized by viscosities acceptable in industrial and agricultural practice (less than 3000 mPa·s at 20°C), remained homogeneous after 14 days of storage at 0°C, 20°C, and 54°C in an aging test, and did not precipitate in the spray liquid even when used in low doses or at high dilutions (they were stable).

[0222] Additionally, the effectiveness of the adjuvant compositions according to the invention and the resulting herbicide formulations were evaluated for their herbicidal effectiveness under field conditions.

[0223] Example 10. Testing the effectiveness of adjuvant composition 5 according to the present invention.

[0224] Adjuvant composition 5 according to the present invention was tested in a field trial conducted in 2021 to determine its effect on the herbicide Roundup 360 Plus (glyphosate) on the herbicidal effectiveness of the test plants, which were a mixture of blue borage, sunflower, white mustard and oilseed radish. The herbicide Roundup 360 Plus was used at a significantly reduced dose of 0.5 l / ha (180 g ai / ha), and the effect of the test composition 5 according to the present invention at a dose of 1.5 l / ha on the herbicidal effectiveness was compared with the same dose of the AS 500SL commercial adjuvant (which includes ammonium sulfate and a cationic surfactant). The spray program was carried out in the 4-6 leaf phase of the test equipment using a boom sprayer equipped with 4 TeeJet-11002VP nozzles, ensuring a spray liquid output of 164 l / ha. The experiment was set up using the parallel strip method, repeated 4 times, and the area of the individual plots was 10 m 2 The herbicidal effectiveness of the herbicide Roundup 360 Plus on the test plants was visually assessed 7 and 14 days after treatment with and without the tested adjuvants. The results presented in Table 4 show that, regardless of the date of assessment, the adjuvant composition 5 obtained according to the invention activated the herbicidal effectiveness of glyphosate on the test plants more strongly than the reference adjuvant AS 500SL.

[0226]

[0227] Example 11. Testing of the herbicidal effectiveness of herbicide formulation 3 according to the invention.

[0228] In a field experiment set up in 2022 in an area not used for agriculture, a herbicide formulation 3 according to the present invention containing 180 g of glyphosate in 1 l was tested to determine its herbicidal effectiveness. The weed infestation in the experimental fields was dominated by the following weed species: brome sp., cocksfoot, meadow bluegrass, couch grass, common yarrow and white clover. Herbicide formulation 3 was used at a dose of 720 g ai of glyphosate and was compared with the commercial herbicides Roundup 360 Plus (doses of 1440 and 720 g ai / ha) and Halvetic (glyphosate 180 g ai in 1 l with a built-in adjuvant containing ammonium sulfate and a mixture of surfactants and alkyl polyglycoside groups), also at a dose of 720 g ai / ha. The spraying procedure was carried out in spring at a height of 10-25 cm above the test plants using a bicycle boom sprayer equipped with 5 TeeJet-11002VP nozzles, ensuring a spray liquid output of 150 l / ha. The experiment was carried out using the parallel strip method with 4 replicates and the area of the individual plots was 10 m 2 A visual assessment of the herbicidal effectiveness of the herbicide formulation 3 according to the invention was carried out 2 weeks and 6 weeks after treatment. The results presented in Table 5 show that, regardless of the date of assessment, the herbicide formulation 3 according to the invention, applied at a dose of 720 g ai. / ha, showed significantly greater effectiveness than the commercial herbicide Roundup 360 Plus used at a twice higher dose (1440 g ai. / ha), significantly higher than the same herbicide used at a comparable dose (720 g ai / ha) and significantly higher than Havetic herbicide, also used at a comparable dose (720 g ai / ha).
