Description

[0001] SYNERGISTICALLY EFFECTIVE HERBICIDE COMPOSITION COMPRISING PYRIDATE AND FENQUINOTRIONE

[0002] TECHNICAL FIELD

[0003] The invention relates to a synergistically effective herbicide composition comprising pyridate and fenquinotrione, to a kit comprising pyridate and fenquinotrione, and to a use of a herbicide composition according to the invention for controlling one or more types of unwanted vegetation.

[0004] BACKGROUND

[0005] In crop protection, it is in principle desirable to increase the specific action of a herbicidally active substance and the safety of operation. The herbicidal activity of many herbicides against unwanted vegetation is already on a high level, but generally depends on the application rate, the respective preparation form, the respective unwanted vegetation to be controlled or the spectrum of unwanted vegetation, the climatic and soil conditions, etc. Thus, there is frequently a need for targeted synergistic activity against specific species of unwanted vegetation, control of unwanted vegetation with better overall selectivity, generally lower amounts of active compounds used for equally good control results, and for a reduced active compound input into the environment to avoid, for example, leaching and carry-over effects. However, in the combined use of a plurality of active compounds, there are frequently phenomena of chemical, physical, or biological incompatibility, such as decomposition of an active compound or antagonism in the biological activity of the active compounds.

[0006] The present invention aims to resolve at least some of the problems mentioned above. It is furthermore an object of the present invention to provide herbicide compositions as alternatives to the prior art, or as improvements thereof.

[0007] SUMMARY OF THE INVENTION

[0008] A first aspect of the present invention provides a synergistically effective herbicide composition according to claim 1. In the herbicide composition according to the first aspect of the present invention, fenquinotrione and pyridate are present according to a weight ratio of between 1:50 and 5:3. Fenquinotrione has shown an unexpected increase in herbicidal activity when combined with pyridate. This increase in herbicidal activity is caused by a synergistic effect when combining pyridate with fenquinotrione according to the herein described weight ratio.

[0009] Preferred embodiments of the composition are shown in dependent claims 2 to 6.

[0010] A second aspect of the present invention provides a method according to claim 7.

[0011] Preferred embodiments of the method are shown in dependent claims 8 to 15.

The terms or definitions used herein are provided solely to aid in the understanding of the invention.

[0021] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to a person skilled in the art from this disclosure, in one or more embodiments. Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those in the art.

[0022] A first aspect of the present invention relates to a synergistically effective herbicide composition comprising fenquinotrione and pyridate, wherein said fenquinotrione and said pyridate are present in the composition according to a weight ratio of between 1 :50 and 5:3. The term "unwanted vegetation", as used herein, refers to all plants, such as, for example, broad-leaved weeds, weed grasses or Cyperaceae, which grow at sites where they are unwanted.

[0023] In light of the present invention, "fenquinotrione" is to be interpreted as a herbicide with a chemical structure defined as 2-[8-chloro-4-(4-methoxyphenyl)-3-oxo-3,4- dihydro(quinoxaline-2-carbonyl)]cyclohexane-l, 3-dione, otherwise represented by the chemical formula C22H17CIN2O5. Fenquinotrione effectively controls a wide range of broadleaf and sedge weeds, demonstrating superior rice selectivity and efficacy against acetolactate synthase inhibitor-resistant weeds. Its mechanism of action involves the potent inhibition of 4-hydroxyphenylpyruvate dioxygenase (4-HPPD).

[0024] In a broader sense, as used herein, the term "4-HPPD inhibitors" thus refers to a group of herbicides that indirectly inhibit phytoene desaturase by inhibiting synthesis of plastoquinone (PQ), an essential cofactor for the desaturase. 4- Hydroxyphenylpyruvate dioxygenase (4-HPPD; EC 1.13.11.27) is an enzyme that is involved in the metabolic pathway for the synthesis of plastoquinone from tyrosine. This takes place in the chloroplast and is the same pathway that leads to biosynthesis of a-tocopherol, a powerful antioxidant. PQ is not only an essential cofactor for phytoene desaturase but is also an essential carrier of protons and electrons in the thylakoid membrane. Hence, 4-HPPD inhibitors not only indirectly inhibit phytoene desaturase, but may also disrupt thylakoid membrane function and reduce protection from damage by AOS. The group of 4-HPPD inhibitors includes selective herbicides for controlling unwanted vegetation belonging to the F2 classification according to the Herbicide Resistance Action Committee (HRAC) (http: / / www.hracglobal.com). 4- HPPD inhibitors belong to the class of herbicides inhibiting pigment synthesis, also called bleaching herbicides. The group of 4-HPPD inhibitors includes triketones, isoxazoles and pyrazoles. Examples of chemical substances of the group of 4-HPPD inhibitors include triketones, pyrazolones, isoxazoles and other 4-HPPD inhibitors. The group of triketones includes, yet is not limited to, fenquinotrione, mesotrione, sulcotrione, tembotrione, tefuryltrione, pyraquinate, quinotrione, benquinotrione, tripyrasulfone and fenpyrazone. The group of pyrazolones includes, yet is not limited to, pyrazoxyfen, pyrazolynate, benzofenap, pyrasulfotole, topramezone and tolpyralate. The group of isoxazoles includes, yet is not limited to, isoxaflutole and isoxachlortole. The so-called group of "other 4-HPPD inhibitors" includes, yet is not limited to, benzobycyclon, bicyclopyrone and metproxybicyclone. The term "pyridate" refers a selective contact herbicide with the molecular formula C19H23CIN2O2S, and is a potent post-emergent agent used to control a variety of monocotyledonous and dicotyledonous weeds. It functions by inhibiting photosynthetic electron transport at the photosystem II receptor site, primarily absorbing through leaf surfaces.

[0025] In a broader sense, the terms "phenyl-pyridazines" and "phenyl-pyridazine herbicides", as used herein, are synonyms, and include selective herbicides for controlling unwanted vegetation belonging to the C3 classification according to the Herbicide Resistance Action Committee (HRAC) (http: / / www.hracglobal.com). Phenyl-pyridazines belong to the class of the photo system II inhibitors. The class of phenyl-pyridazines includes pyridate and pyridafol, and derivatives or salts thereof.

[0026] The term "photosystem II inhibitors" refers to chemical compounds which have a herbicidal activity by inhibiting the photosynthesis process at the level of the photo system II in plants. In particular, photosystem II inhibitors bind to the DI protein of photo system II and thereby inhibit the binding of quinone to the DI protein of photo system II whereby electrons accumulate in chlorophyll molecules and an excess of oxidation occurs, causing the plant to die. The class of substances of the photosystem II inhibitors include triazinone herbicides, urea herbicides, phenylcarbamate herbicides, triazolinone herbicides, nitrile herbicides, amide herbicides, benzothiadiazinone herbicides, phenyl-pyridazine herbicides, and derivatives or salts thereof.

[0027] It is noted that, salts and / or derivatives of pyridate and / or fenquinotrione are also falling within the above definitions of pyridate and fenquinotrione. Any salt is possible as long as it is agriculturally acceptable. Examples thereof include alkali metal salts such as a sodium salt and a potassium salt, alkaline earth metal salts such as a magnesium salt and a calcium salt, ammonium salts such as a monomethylammonium salt, a dimethylammonium salt and a triethylammonium salt, inorganic acid salts such as a hydrochloride, a perchlorate, a sulfate and a nitrate salt, and organic acid salts such as an acetate and a methanesulfonate salt.

[0028] It is furthermore also noted that, although pyridate has proven most efficiently in the herbicide composition according to the first aspect of the present invention, alternative embodiments provide other herbicide compositions that are formulated by applying at least one other phenyl-pyridazine herbicide in addition to or instead of pyridate. Relative amounts of such phenyl-pyridazine herbicide with regard to fenquinotrione and / or alternative 4-HPPD inhibitors, may be included within the ranges disclosed above, or may be situated within other or broader ranges. Said at least one other phenyl-pyridazine herbicide is preferably pyridafol or a derivative or salt thereof.

[0029] The wording "synergistically effective", in light of the present invention refers to a combination of two or more substances, in this case, pyridate and fenquinotrione, which when used together produce a greater effect than the sum of their individual effects. This synergism implies that the combined action of these herbicides is more effective at controlling weeds than when they are used separately. The Colby calculation is often used to quantify this synergy. It is a mathematical formula that predicts the expected effectiveness of a combination of substances based on their individual efficacies.

[0030] A synergistic effect in herbicides is always present when the herbicidal action of the active compound combination exceeds the action of the active compounds when applied individually.

[0031] The expected activity of a given combination of herbicides A and B can be calculated as follows according to a calculation method by Colby (cf. COLBY, S. R.: "Calculating synergistic and antagonistic responses of herbicide combinations", Weeds 15, pages 20-22, 1967), the equation reading:

[0032] E = X + Y - (X x Y) / 100 wherein:

[0033] X is the amount of damage (expressed in %) done by herbicide A at an application rate of m g / ha,

[0034] Y is the amount of damage (expressed in %) done by herbicide B at an application rate of n g / ha, and

[0035] E is the expected amount of damage (expressed in %) done by the combination of herbicides A and B at their respective application rates of m and n g / ha.

[0036] If the actual damage exceeds the calculated value (E), the activity of the combination is superadditive, i.e. it shows a synergistic effect. In this case, the damage actually observed must exceed the values calculated using the above formulae for the expected damage E.

[0037] The herbicidal activity of herbicides comprising pyridate or pyridate herbicides against unwanted vegetation (among which broad-leaved weeds, weed grasses, cyperaceae) is already on a high level, but generally depends on the application rate, the respective preparation form, the respective unwanted vegetation to be controlled or the spectrum of unwanted vegetation, the climatic and soil conditions, etc. Further criteria in this context are duration of action, or the breakdown rate, of the herbicide, the general crop plant compatibility and speed of action (more rapid onset of action), the activity spectrum and behavior toward follower crops (replanting problems) or the general flexibility of application (control of unwanted vegetation in their various growth stages). If appropriate, changes in the susceptibility of unwanted vegetation, which may occur on prolonged use of the herbicides or in limited geographical regions (control of tolerant or resistant species of unwanted vegetation), may also have to be taken into account. The compensation of losses in action in the case of individual plants of unwanted vegetation by increasing the application rates of the herbicides is only possible to a certain degree, for example because such a procedure reduces the selectivity of the herbicides or because the action is not improved, even when applying higher rates.

[0038] Thus, there is frequently a need for targeted synergistic activity against specific species of unwanted vegetation, control of unwanted vegetation with better overall selectivity, generally lower amounts of active compounds used for equally good control results and for a reduced active compound input into the environment to avoid, for example, leaching and carry-over effects. There is also a need for control of species which were as yet uncontrolled (gaps) and for control of species which are tolerant or resistant to individual herbicides or to a number of herbicides. There is also a need for developing one-shot applications to avoid labor-intensive multiple applications, and also to develop systems for controlling the rate of action, where, in addition to an initial rapid control of unwanted vegetation, there is also a slow, residual control.

[0039] A possible solution to the problems mentioned above may be to provide combined herbicide compositions, that is combinations of a plurality of herbicides and / or other components from the group of the agrochemically active compounds of a different type and of formulation auxiliaries and additives customary in crop protection which contribute the desired additional properties. However, in the combined use of a plurality of active compounds, there are frequently phenomena of chemical, physical or biological incompatibility, for example decomposition of an active compound or antagonism in the biological activity of the active compounds. For these reasons, potentially suitable combinations of active compounds have to be selected in a targeted manner and tested experimentally for their suitability, it not being possible to safely discount a priori negative or positive results.

[0040] Fenquinotrione has shown an unexpected increase in herbicidal activity when combined with pyridate. This increase in herbicidal activity is caused by a synergistic effect when combining pyridate with fenquinotrione according to the herein described weight ratio.

[0041] By preference, said fenquinotrione and said pyridate are present in the composition according to a weight ratio of between 1 :20 and 1 :2. More by preference, said fenquinotrione and said pyridate are present in the composition according to a weight ratio of between 1 : 19 and 1:2, of between 1: 18 and 1:2, of between 1: 17 and 1 :2, of between 1 : 16 and 1 :2, of between 1 : 15 and 1 :2, of between 1 : 14 and 1 :2, of between 1 : 13 and 1 :2, of between 1 : 12 and 1 :2, of between 1: 11 and 1 :2, or of between 1 : 10 and 1 :2. Even more by preference, said fenquinotrione and said pyridate are present in the composition according to a weight ratio of between 1 : 10 and 1 :3, or of between 1: 10 and 1:4. Most by preference, said fenquinotrione and said pyridate are present in the composition according to a weight ratio of between 1 : 10 and 1 :5. With increasing preference, within the herein specified ratio, the synergistical effect was further improved.

[0042] According to a further or another embodiment, said composition comprises from 0,2 to 45 wt.% of fenquinotrione. According to a further or another embodiment, said composition comprises from 4 to 70 wt.% of pyridate.

[0043] In some embodiments, the composition is formulated as an oil dispersion (OD), as a water dispersible granules (WG), as an emulsifiable concentrate (EC), as a wettable powder (WP), as a micro-emulsion (ME), or as a capsule suspension (CS).

[0044] In light of the present invention, the wording "oil dispersion (OD)" must be interpreted as a stable suspension of active ingredients in a water immiscible fluid, which may optionally contain other dissolved active ingredients, intended for dilution with water before use. The term "water dispersible granules (WG)" refers to a formulation consisting of granules to be applied after disintegration and dispersion in water. An "emulsifiable concentrate (EC)" is to be read as a liquid, homogeneous formulation to be applied as an emulsion after dilution in water, more in particular, a liquid formulation consisting of a solvent, emulsifier, and the active ingredient. The wording "wettable powder (WP)" reads onto a powder formulation to be applied as a suspension after dispersion in water. It forms a suspension rather than a true solution, requiring agitation to stay mixed. A "micro-emulsion (ME)" is a clear, stable, and fine emulsion with droplet sizes significantly smaller than those in a standard emulsion, or more in particular, a clear to opalescent, oil and water containing liquid, to be applied directly or after dilution in water, when it may form a diluted micro-emulsion or a conventional emulsion. The term "capsule suspension (CS)" in light of the present invention is to be read as a formulation wherein the active ingredient is encapsulated in tiny, polymeric capsules suspended in a liquid, normally intended for dilution with water before use. This type provides controlled release of the active ingredient, reduced exposure risk, and can enhance stability and effectiveness.

[0045] According to a preferred embodiment, the composition is formulated as an oil dispersion (OD). Formulating the composition as such is beneficial in that the formulation may be easily mixed with water and has improved stability during storage. Said composition preferably comprises between 1 and 10 wt.% of fenquinotrione, and between 10 and 45 wt.% of pyridate. More by preference, said composition comprises between 1,25 and 7,5 wt.% of fenquinotrione, and between 12,5 and 42,4 wt.% of pyridate.

[0046] According to another preferred embodiment, the composition is formulated as a water dispersible granules (WG). This is especially advantageous in that this formulation type minimizes dust, improves safety, and ensures even distribution of the active ingredient in e.g. a spray tank. Said composition preferably comprises between 0,5 and 15 wt.% of fenquinotrione, and between 5 and 65 wt.% of pyridate. More by preference, said composition comprises between 0,75 and 12,5 wt.% of fenquinotrione, and between 7,5 and 60 wt.% of pyridate.

[0047] According to still another preferred embodiment, the composition is formulated as an emulsifiable concentrate (EC). Formulating the composition as an EC has the advantage that, when mixed with water, it forms an emulsion, allowing for easy and effective application. Said composition preferably comprises between 1 and 15 wt.% of fenquinotrione, and between 10 and 70 wt.% of pyridate. More by preference, said composition comprises between 1,25 and 12 wt.% of fenquinotrione, and between 12,5 and 65 wt.% of pyridate.

[0048] According to still another preferred embodiment, the composition is formulated as a wettable powder (WP). Said composition preferably comprises between 0,5 and 15 wt.% of fenquinotrione, and between 5 and 65 wt.% of pyridate. More by preference, said composition comprises between 0,75 and 12,5 wt.% of fenquinotrione, and between 7,5 and 60 wt.% of pyridate.

[0049] According to still another preferred embodiment, the composition is formulated as a micro-emulsion (ME). Said composition preferably comprises between 0,5 and 10 wt.% of fenquinotrione, and between 7,5 and 50 wt.% of pyridate. More by preference, said composition comprises between 1,75 and 8,5 wt.% of fenquinotrione, and between 8 and 46 wt.% of pyridate.

[0050] According to still another preferred embodiment, the composition is formulated a capsule suspension (CS). Said composition preferably comprises between 1 and 10 wt.% of fenquinotrione, and between 10 and 45 wt.% of pyridate. More by preference, said composition comprises between 1 and 7,5 wt.% of fenquinotrione, and between 12,5 and 42,4 wt.% of pyridate.

[0051] Formulating the composition as a wettable powder (WP), as a micro-emulsion (ME), or as a capsule suspension (CS) may be beneficial in that they may offer reduced solvent use compared to e.g. EC formulations, or may lead to improved stability and often enhanced bioavailability of the active ingredient.

[0052] According to a further or another embodiment, said composition comprises less than 2 wt.% of residual water, based on the total weight of the composition. A low amount of residual water as described herein is beneficial towards stability during storage, as well as during application. By preference, the composition is formulated as an oil dispersion (OD), as a water dispersible granules (WG), as an emulsifiable concentrate (EC), as a wettable powder (WP), as a micro-emulsion (ME), or as a capsule suspension (CS), wherein the composition comprises less than 2 wt.% of residual water, based on the total weight of the composition. More by preference, said composition comprises less than 1,9 wt.%, less than 1,8 wt.%, less than 1,7 wt.%, less than 1,6 wt.%, less than 1,5 wt.%, less than 1,4 wt.%, less than 1,3 wt.%, less than 1,2 wt%, or less than 1,1 wt.% of residual water, based on the total weight of the composition. With increasing preference, stability, efficacy, shelf-life and / or handling of the composition may be further improved.

[0053] Even more by preference, said composition comprises less than 1 wt.% of residual water, based on the total weight of the composition. Even more by preference, the composition is formulated as an oil dispersion (OD), as a water dispersible granules (WG), or as an emulsifiable concentrate (EC), wherein the composition comprises less than 1 wt.% of residual water, based on the total weight of the composition. Low amounts of residual water as described herein are beneficial towards stability during storage, as well as during application, and may further improve efficacy and / or handling of the composition.

[0054] According to a further or another embodiment, said composition comprises less than

[0055] 1 wt.% of residual water, based on the total weight of the composition. According to some more preferred embodiments, said composition comprises less than 0,9 wt.% of residual water, less than 0,8 wt.%, less than 0,7 wt.%, less than 0,6 wt.%, less than 0,5 wt.%, less than 0,4 wt.%, less than 0,3 wt.%, less than 0,2 wt.%, or even less than 0,1 wt.% of residual water, based on the total weight of the composition.

[0056] According to a further or another embodiment, the composition comprises at least

[0057] 2 wt.% of additional components, selected from the group of auxiliaries and other agrochemically active compounds, said auxiliaries preferably including the residual water, based on the total weight of the composition. For example, the composition may comprise 5 wt.% of auxiliaries, of which less than 2 wt.% is residual water, based on the total weight of the composition.

[0058] By preference, the composition comprises at least 3 wt.% of additional components, based on the total weight of the composition. More by preference, the composition comprises at least 4 wt.% of additional components, at least 5 wt.%, or at least 6 wt.% of additional components, based on the total weight of the composition. Even more by preference, the composition comprises at least 10 wt.%, at least 20 wt.%, at least 30 wt.%, at least 40 wt.%, or at least 50 wt.% of additional components, based on the total weight of the composition. Even more by preference, the composition comprises at least 60 wt.%, at least 70 wt.%, at least 80 wt.%, or even at least 90 wt.% of additional components, based on the total weight of the composition.

[0059] According to some embodiments, said additional components are selected from the group comprising other pesticides such as herbicides, insecticides, fungicides, secondary 4-HHPD inhibitors, or other active pesticide ingredients, safeners, antioxidants, chemical stabilizers, adhesives, fertilizers, perfumes, colorants, liquid carriers, solid carriers, surface-active agents, crystallization inhibitors, viscosity modifiers, suspending agents, spray droplet modifiers, pigments, foaming agents, light-blocking agents, compatibility agents, antifoam agents, sequestering agents, neutralizing agents and buffers, wetting and dispersing agents, preservatives, thickening agents, corrosion inhibitors, freezing point depressants, odorants, spreading agents, penetration aids, micronutrients, emollients, lubricants, sticking agents and humectants, such as, for example, propylene glycol. According to preferred embodiments, the herbicide composition can also comprise various agrochemically active compounds, for example from the group of the acaricides, nematicides, bird repellants, and soil structure improvers.

[0060] The term 'safener', as used in this text, is to be understood as a compound or a mixture of compounds which compensates for, or reduces, the phytotoxic properties of a herbicide towards useful plants without substantially reducing the herbicidal action against unwanted vegetation.

[0061] Non-limiting examples of colorants include inorganic pigments such as iron oxide, titanium oxide and Prussian blue and / or organic dyes such as alizarin dyes, azo dyes and metal phthalocyanine, and trace elements such as iron, manganese, boron, copper, cobalt, molybdenum and zinc.

[0088] The term "crop plant" is to be interpreted as a plant grown in significant quantities in agricultural or horticultural practices for the purpose of harvesting a product of value, such as food, feed, fiber, oil, biomass, medicinal substances, or ornamentals. Taking the aspect of "value" into account, the term "crop plant" may also be interpreted in a broader sense as a "desired plant", which may ultimately also relate to non-crops, e.g. railway tracks. In light of the present invention, when referring to the wording "habitat", indication is made to the specific environment or area in which a crop plant is cultivated. This includes the physical and biological conditions that affect the growth and development of the crop, such as soil type, climate, water availability, and the presence of other organisms.

[0089] Fenquinotrione has shown an unexpected increase in herbicidal activity when combined with pyridate.

Table 1 delineates exemplary embodiments of herbicidal compositions encompassing fenquinotrione and pyridate as the active constituents. These embodiments are illustrative of the synergistic weight ratios that fall within the scope of the present invention, as detailed in the appended claims. The compositions are presented in various formulation types including oil dispersion (OD), water dispersible granules (WG), emulsifiable concentrate (EC), and others, each tailored to optimize application efficacy and handling characteristics. The specified weight percentages of fenquinotrione and pyridate are judiciously chosen to maintain the physical stability of the formulations and to conform to the efficacious range for target weed species control. Additionally, the residual water content is chosen as such to ensure product integrity and prolong shelf life. These examples are provided to exemplify the breadth of the inventive compositions and are not intended to limit the scope of the invention as defined by the claims.

[0116] Table 1. Exemplary compositions according to the invention.

[0117] In the following examples, herbicidal activity of herbicide compositions according to the first aspect of the present invention with regard to different types of unwanted vegetation was determined during trials performed on test fields (field trials). Individual compositions comprising pyridate and individual compositions fenquinotrione are compared with a herbicide composition according to the invention comprising both pyridate and fenquinotrione. The expected activity of the combination of the active compounds pyridate and fenquinotrione is calculated according to the calculation method by Colby, in order to evaluate a synergistic effect between pyridate and fenquinotrione. If the actual herbicidal activity exceeds the calculated value, the activity of the combination is superadditive, i.e. it shows a synergistic effect.

[0118] Herbicidal activity was determined by applying herbicide compositions on emerged unwanted vegetation on fields where maize, rice or cereal was cultivated. Pyridate and fenquinotrione were applied as a tank mixture by mixing these active compounds prior to use in a spray tank. The corresponding mixture was in the form of a spray liquor. Besides, spray liquors of individual compositions comprising pyridate and of individual compositions comprising fenquinotrione were used. Test plants of unwanted vegetation with a growth stage corresponding to BBCH 10-18 (according to the extended BBCH-scale) were sprayed with the active compound preparations such that particular desired amounts of active compounds are applied per unit area. Spray liquor was diluted with water to arrive at an application volume of 50 to 450 L / ha. At a specified number of days after application (DAA), the degree of damage to the unwanted vegetation is rated in percentage (%) of plants of unwanted vegetation that were killed, which was assessed by visually controlling the plants.
