Description

[0001] This invention relates to compositions, preferably for agricultural use, in the form of an emulsion concentrate (EW) comprising a combination of at least one water-soluble herbicide, at least one water-insoluble herbicide, and a specific surfactant.

[0002] The present invention also relates to a method for preventing or controlling unwanted plants or affecting plant growth, the method comprising applying a composition to soil or plants.

[0003] The present invention also relates to a method for preparing the composition.

[0004] Pesticides are widely used in agricultural pest control. Given their widespread use, there has always been a need to develop methods to enhance pesticide efficacy. A common method to improve the potency of active ingredients is to combine them with one or more other active ingredients having the desired activity spectrum. This combination can produce highly effective synergistic products with broad coverage, potentially reducing the application rate of the active ingredient. Therefore, modern agrochemical practice often favors combination products containing active ingredients with specific activity spectra. Furthermore, appropriate adjuvants can be used to enhance the performance of active ingredients and / or strengthen the physical properties of formulations. Typically, active ingredients are formulated with various formulation adjuvants to enhance their activity. Agrochemical formulations can be developed in various ways, primarily based on the physical and chemical properties of the active ingredient. Examples of such formulations include aqueous solutions, emulsifiable concentrates, encapsulated suspensions, wetting powders, oil-in-water or water-in-oil emulsions, suspension emulsions, suspension solutions, microemulsions, emulsions, ZC formulations, and granules.

[0005] Herbicide formulations based on water-soluble herbicides are well known. For example, glufosinate is a water-soluble, non-selective foliar contact herbicide that kills or controls a wide variety of weeds. Typically, glufosinate is used in non-selective treatments and for controlling broadleaf weeds, grasses, and sedges in cereals, cotton, corn and soybeans, orchards, vineyards, rubber and oil palm plantations, ornamental trees and shrubs, non-cultivated land, and a broad range of pre-emergence vegetable crops. Water-soluble herbicides are preferably formulated as aqueous solutions with the addition of other water-soluble ingredients / adjuvants.

[0006] To ensure optimal bioavailability of water-soluble herbicides, one or more specific adjuvants are known to be used in glufosinate-based formulations. However, some of these adjuvants have drawbacks in off-the-shelf formulations containing water-soluble herbicides, particularly glufosinate.

[0007] Another common practice to enhance the activity of water-soluble herbicides (especially glufosinate) is to combine them with one or more other active ingredients that have the desired activity spectrum. This combination can produce highly effective synergistic products with broad-spectrum coverage and may also reduce the application rate of the active ingredient. However, when water-insoluble active ingredients are combined with water-soluble herbicides, for example in the form of emulsions or dispersions, attention must be paid to the physical and chemical stability of the formulation.

[0008] Furthermore, pesticide formulations in emulsion form, as described in applications such as WO2002 / 43488, WO2007 / 057028, or DE69012487, are not entirely satisfactory in terms of stability and viscosity.

[0009] More specifically, aqueous continuous phases do not exhibit high ionic strength characteristics and do not contain large amounts of salts or ionic components, such as glufosinate. Stabilizing emulsions in continuous phases that exhibit high ionic strength and are rich in electrolytes is particularly challenging.

[0010] It is particularly difficult to confirm the appropriate relationship between adjuvants and co-formulated formulations, so that concentrated high-ionic-strength oil-in-water emulsions can have good stability during storage (low temperature, high temperature) and maintain suitable emulsion properties after being diluted in the final carrier (usually water, which has lower ionic strength properties) before field application.

[0011] For these reasons, pesticide emulsions may cause physical instability issues. In particular, pesticide emulsions may experience emulsion / oil layer separation, dehydration shrinkage, and / or sedimentation during storage, especially under various temperature conditions. In addition to such physical compatibility issues, decomposition or antagonism of the active ingredient under consideration and / or biocompatibility issues are also frequently encountered.

[0012] Therefore, there is a constant need to provide improved water-soluble herbicide-based compositions for agricultural needs, particularly glufosinate-based compositions, which possess favorable inherent properties, especially good physicochemical properties such as good storage stability and suitable viscosity characteristics (good pourability). Such compositions should produce good performance upon dilution, including good homogeneity of emulsions and / or dispersions of potentially water-insoluble agricultural materials, even for high-loading formulations.

[0013] This invention achieves these objectives, and its subject matter is a composition, preferably for agricultural use, in the form of an oil-in-water emulsion (EW), comprising: (i) at least one water-soluble herbicide, (ii) at least one water-insoluble herbicide, and not dimethyl phenoxychloride or dimethyl phenoxychloride-P. (iii) A surfactant mixture (M) comprising: a. At least one nonionic surfactant selected from oxyalkylenated fatty alcohols; b. At least one nonionic surfactant selected from ethylene oxide and propylene oxide condensates; and c. At least one phosphate ester surfactant.

[0014] The composition is free of dimethyl phenoxychloride and dimethyl phenoxychloride-P.

[0015] The compositions according to the present invention have good inherent physicochemical properties.

[0016] Furthermore, it is noted that the compositions according to the invention advantageously ensure good performance upon dilution, including good homogeneity of emulsions and / or dispersions of water-insoluble agricultural materials, even in high-load formulations.

[0017] Furthermore, it is noted that the compositions according to the invention have suitable viscosity characteristics and good pourability, thus making them easier to apply. Surprisingly, no other rheology modifiers are required to stabilize the compositions other than the surfactant mixture (M).

[0018] More specifically, the compositions according to the invention advantageously demonstrate that: - Good storage stability, especially at room temperature (20°C), or even at high temperatures, such as 54°C for 2 weeks; - Suitable properties after dilution with water at the target utilization rate; - Suitable viscosity characteristics and good pourability; - Satisfactory can-mix compatibility; and / or - Excellent biological efficacy.

[0019] As used herein, a stable composition can be defined as a composition that does not exhibit signs of instability such as phase separation, dehydration shrinkage, flocculation, sedimentation, emulsification, or the presence of macroscopic oil droplets on the sample surface. Advantageously, a stable composition is a formulation that does not exhibit any of the signs of instability described above after being stored at the considered temperature for the considered time.

[0020] Obtaining concentrated pesticide formulations in the form of oil-in-water emulsions with suitable rheological properties has always been challenging. To achieve good storage stability in such concentrated oil-in-water emulsions, rheology modifiers that produce suspension properties, such as xanthan gum, precipitated silica, or fumed silica, are often used. However, in the presence of xanthan gum or other polysaccharide gums, compatibility issues often arise when mixing with other agrochemicals or fertilizers. The dilution characteristics of concentrated formulations are often unsatisfactory, which is related to the presence of certain rheology modifiers and the presence of sediments or flocculents, which can lead to operational problems such as nozzle clogging. Furthermore, using such rheology modifiers to achieve good stabilization of concentrated oil-in-water emulsions results in increased viscosity response, thus causing operational problems. According to the compositions of the present invention, suitable rheological properties are successfully obtained even in the form of oil-in-water emulsions.

[0021] Furthermore, it is noted that the compositions of the present invention preferably ensure good performance after dilution, even for high-load formulations, and avoid / delay the formation of crystals, even under stringent conditions.

[0022] According to a preferred embodiment of the invention, the composition is an agrochemical formulation containing a high concentration of agricultural materials. The use of a concentrated formulation is particularly advantageous for economic reasons (in fact, such a composition can reduce the total weight of the formulation, thereby lowering its transportation costs), and the concentrated formulation is then typically diluted to the desired concentration by the end user.

[0023] The subject of this invention is also a method for preventing unwanted plants or affecting plant growth, the method comprising applying a composition to soil and / or plants.

[0024] Another subject of the present invention is a method for preparing the compositions according to the present invention.

[0200] The compositions according to the invention may further comprise at least one other agricultural material besides herbicides.

[0201] A variety of agricultural materials are used in agriculture. They are also known as active plant protection products, active materials, or active substances.

[0202] As used herein, the term "agricultural material" refers specifically to active ingredients used in agricultural practices, including soil cultivation for crop growth. However, the use of agricultural materials is not limited to crop application. Agricultural materials can be applied to any surface, for example, for cleaning or to promote or inhibit the growth of organisms. Other non-crop applications include, but are not limited to, application to animals (such as livestock), to turf and ornamental plants, and to railway weeds.

[0203] Agricultural materials are typically products in pure or highly concentrated forms and are generally insoluble in water, as is known to those skilled in the art.

[0204] Determining a suitable solvent to obtain a chemically and physically stable formulation based on the water solubility of agricultural materials and their loading in the target formulation can be very challenging.

[0205] For agricultural materials with low or relatively low water solubility, the use of suitable solvents is therefore of concern for the preparation of concentrated liquid formulations. Concentrated formulations of such agricultural materials are typically diluted before agricultural use. Farmers usually dilute them by mixing agricultural chemicals with water.

[0206] Preferably, the other agricultural materials are those that are heated at 25°C and atmospheric pressure (i.e., 1.013 × 10⁻⁶). 5 Pa) Water-insoluble agricultural materials.

[0216] Preferably, the micronutrients may be selected from zinc, calcium, molybdenum, manganese, or magnesium. More preferably, the micronutrients used in the agrochemical formulation according to the present invention may be selected from zinc oxide, manganese carbonate, manganese oxide, or calcium carbonate.

[0217] Macronutrients generally refer to nutrients containing nitrogen, phosphorus, and potassium, including fertilizers (such as ammonium sulfate) and water conditioners. Suitable macronutrients include fertilizers and other compounds containing nitrogen, phosphorus, or sulfur, as well as water conditioners.

[0218] Suitable fertilizers include inorganic fertilizers that provide nutrients such as nitrogen, phosphorus, potassium, or sulfur. Examples of such fertilizers include: For nitrogen-based nutrients: nitrates and / or ammonium salts, such as ammonium nitrate, including in combination with urea, such as urea-type materials, calcium ammonium nitrate, ammonium thionitrate, ammonium phosphate (especially monoammonium phosphate, diammonium phosphate and polyammonium phosphate), ammonium sulfate, and less commonly used calcium nitrate, sodium nitrate, potassium nitrate and ammonium chloride. For phosphorus as a nutrient: phosphorus in acidic forms (such as phosphoric acid, pyrophosphate, or polyphosphoric acid), but more often in salt forms such as ammonium phosphate (especially monoammonium phosphate, diammonium phosphate, and polyammonium phosphate) and potassium phosphate (especially potassium dihydrogen phosphate and polyphosphate). For sulfur-based nutrients: ammonium sulfate and potassium sulfate, such as mixed sulfates with magnesium.

[0248] The compositions according to the invention can exhibit non-Newtonian "shear-thinning" viscosity, meaning that the viscosity decreases with increasing shear stress within a specific range of shear stress. Two recognized categories of flow behavior are plastic flow and pseudoplastic flow, both of which include shear-thinning flow behavior.

[0249] In one embodiment, the compositions of the present invention exhibit plastic flow behavior. As used herein, the term "plastic" in relation to the flow behavior of a composition refers to a composition exhibiting a characteristic "yield stress" (i.e., the minimum shear stress required to initiate flow) and shear-thinning behavior in certain shear stress ranges above the yield stress. A plastic composition exhibits no flow when subjected to shear stress below its yield stress and flows when subjected to shear stress above its yield stress. In the intermediate shear stress range above its yield stress, the composition typically exhibits non-Newtonian viscosity (decreasing with increasing shear stress, i.e., shear-thinning behavior), while at shear stresses above the intermediate shear stress range, the composition may exhibit viscosity that does not change with shear stress (i.e., Newtonian flow behavior).

[0250] In another embodiment, the compositions of the present invention exhibit pseudoplastic flow behavior. As used herein, the term "pseudoplastic" in relation to the flow behavior of a composition refers to a composition exhibiting a decrease in viscosity with increasing shear stress (i.e., shear thinning behavior).

[0251] Under various conditions, compositions exhibiting plastic or pseudoplastic rheological properties resist flow under low shear stress, but when subjected to increased shear stress (e.g., when shaken in a bottle or squeezed through a perforation), the composition flows and can be easily pumped, poured, or otherwise dispensed from the container. Typically, settling or storage conditions are low-shear processes with shear rates around 10⁻⁶. -6 per second (1 / s or equivalent to s) -1 - Approximately 0.01 s -1 Within this range, pumping or dumping is a relatively high shear process, with a shear rate greater than or equal to approximately 1 s. -1 More typically 100 s -1 -1000 s -1 Within the range.

[0252] The viscosity of the composition can be measured, for example, at 20°C using a Brookfield RV viscometer (Ametek) equipped with rotors No. 2, 3, or 4, at 20 revolutions per minute (“rpm”) for 1 minute.

[0253] Preferably, the composition according to the invention in the form of an aqueous emulsion concentrate (EW) has a viscosity in the range of 300 mPa·s to 4500 mPa·s, more preferably 450 to 3500 mPa·s, even more preferably 600 to 3000 mPa·s, particularly in the range of 800 to 2500 mPa·s, for example 1000 to 2000 mPa·s, at 20°C and atmospheric pressure (1.013 × 10⁻⁶). 5 The viscosity was measured at 20 rpm using a Brookfield RV viscometer at a pressure of Pa, and it exhibited good pourability.

Ten measurements can be performed at 20°C. -3 s -1 -200 s -1 The shear rate scan, with 10 points per decibel, allows for a 1-minute stabilization time. The static yield stress value is determined as the applied shear stress value at which the viscosity begins to decrease.

[0256] Preferably, using a standard controlled stress rheometer, the composition of the present invention is measured in 100 s. -1 The viscosity shown below is 400-2000 mPa·s, preferably 450-1800 mPa·s, more preferably 500-1600 mPa·s, even more preferably 550-1400 mPa·s, and especially in the range of 600-1200 mPa·s, which advantageously provides good pourability and / or pumpability at high shear rates.

[0257] Preferably, the composition of the present invention exhibits a yield stress value of 0.5-5 Pa, more preferably 0.6-4 Pa, even more preferably 0.7-3 Pa, better preferably 0.8-2.5 Pa, and even better preferably 0.9-2 Pa.

Specifically, it refers to a composition with a suitable viscosity after dilution to the target utilization rate, preferably less than 300 cP (i.e., 300 mPa·s), at 20°C and atmospheric pressure (1.013 × 10⁻⁶). 5 The viscosity was measured at 20 rpm using a Brookfield RV viscometer at 20 rpm, preferably less than 200 cP, and even better less than 100 cP.

[0270] Known conventional methods for preparing agricultural chemical agents can be used. This can be achieved by simply mixing the components.

[0271] The present invention also relates to a method for preparing a composition according to the invention, wherein, in order to form an oil-in-water emulsion, the aqueous phase of the composition as described above is added to the oil phase of the composition as described above, preferably in multiple portions.

[0272] More preferably, the aqueous phase is added to the oil phase in four separate additions, with mixing steps interspersed between each addition.

[0273] According to a preferred embodiment of the invention, an aqueous phase containing (i) at least one water-soluble herbicide and optionally at least one anionic surfactant is added (preferably in multiple additions, more preferably in quarters) to an oil phase containing at least one water-insoluble herbicide and surfactant mixture (M) that is not dimethyl phenoxylate or dimethyl phenoxylate-P, said surfactant mixture (M) comprising: a. At least one nonionic surfactant selected from oxyalkylene fatty alcohols. b. At least one nonionic surfactant selected from ethylene oxide and propylene oxide condensates; and c. At least one phosphate ester surfactant; A mixing step is performed between each addition of the aqueous phase.

[0274] The compositions according to the invention can be used to kill or inhibit harmful organisms and / or clean and / or inhibit the growth of unwanted plants.

[0275] The compositions according to the invention can be diluted and applied in a conventional manner to at least one plant, the area adjacent to the plant, soil suitable for supporting plant growth, plant roots and / or plant leaves; for example by watering (root irrigation), drip irrigation, spraying and / or atomization.

[0276] The compositions according to the invention can be applied before, during, and / or after the emergence of undesirable plants, preferably during and / or after emergence. In one embodiment, application is made before crop emergence, and the crop is planted in a location where the undesirable plant is present or intended to be present. In another embodiment, application is made before crop planting.

[0277] The terms “undesirable plant,” “undesirable species,” “unwanted plant,” “harmful plant,” “unwanted weed,” or “harmful weed” as used in this article are synonymous; and the term “site” as used in this article refers to an area where vegetation or plants grow or will grow, usually a field.

[0278] The herbicidal composition according to the invention can be applied before or after crop sowing (planting), but before crop emergence, especially before sowing. The herbicidal composition is typically applied up to 9 months, often up to 6 months, and preferably up to 4 months before crop planting.

[0279] A significant advantage of the herbicidal composition is its excellent post-emergence herbicidal activity, i.e., its effective control of emerging unwanted plants. Therefore, in a preferred embodiment, the herbicidal composition is applied during or after the emergence of unwanted plants. Post-emergence application of the herbicide composition is particularly advantageous when the unwanted plants are in the leaf development stage up to flowering. These compositions are especially useful for controlling well-grown unwanted vegetation that is difficult to control with conventional mixtures, such as when weeds are more than 10 cm tall, or even more than 15 cm, and / or when dealing with heavily infested weed populations.

[0280] Herbicide compositions can be applied using conventional techniques familiar to skilled personnel. Suitable methods include spraying, atomization, dusting, dispersing, or watering. The choice of application method depends on the intended purpose, but should ensure the best possible distribution of the active ingredient.

[0281] In one embodiment, the herbicide composition according to the invention is applied to the site primarily by spraying, especially after dilution with water. Application can be performed using conventional spraying techniques, with a spray rate of approximately 10 to 2000 L / ha or 50 to 1000 L / ha (e.g., 100 to 500 L / ha). The desired application rate of the herbicide composition depends on the density of the unwanted vegetation, the growth stage of the plants, the climatic conditions of the site where the mixture is applied, and the method of application.

[0282] In the above description, all preferred embodiments of the components can be used alone or in combination.

[0283] The following examples are used to illustrate the present invention. Example

[0284] Example 1: Emulsion preparation and composition: The following aqueous emulsion concentrates (EW) A1 and A2 (of the present invention) and A3 to A9 (comparative examples) were prepared according to method 1 or method 2 described below.

[0285] Method 1: An organic phase is prepared by adding a water-insoluble herbicide from a solvent to a beaker, followed by the addition of surfactants a), b) and / or c), and gently stirring.

[0286] In another beaker, an aqueous phase is prepared by adding an antifoaming agent (if present), glycerol or a water-soluble solvent, deionized water, a water-soluble herbicide (e.g., glufosinate-ammonium (racemic or L-enantiomer)), and then sodium lauryl ether sulfate. The aqueous phase is homogenized using high-shear mixing (IKA Ultraturrax T25, 7000 rpm, for 2 minutes). For emulsion preparation, one-quarter of the aqueous phase is added to the organic phase under high-shear mixing (IKA Ultraturrax T25, 3000 rpm, for 30 seconds). The same method is used for the second, third, and fourth quarters. After the aqueous phase is completely incorporated into the oil phase, high-shear mixing (IKA Ultraturrax T25, 3000 rpm, for 2 minutes) is applied.

[0287] Method 2: The organic phase was prepared in a standard container with reverse blades and equipped with a high-shear impeller (e.g., a Rushton impeller or a dissolving blade): a water-insoluble herbicide was added to a solvent, followed by the addition of surfactants a), b) and / or c), heated at 60°C for 1 hour as needed, then cooled to room temperature (25°C) and gently stirred.

[0288] In a beaker, an aqueous phase is prepared by adding an antifoaming agent (if present), glycerol or a water-soluble solvent, deionized water, a water-soluble herbicide (e.g., glufosinate-ammonium (racemic or L-enantiomer)), and an anionic surfactant such as sodium lauryl ether sulfate.

[0289] The aqueous phase was homogenized using high-shear mixing (IKA Ultraturrax T25, 7000 rpm, for 2 minutes). When preparing the emulsion, one-quarter of the aqueous phase was added to the organic phase under high-shear mixing (600 rpm). The same method was used for the second, third, and fourth quarters. After the aqueous phase was completely incorporated into the oil phase, high-shear mixing (Heidolph overhead stirrer, 2000 rpm) was applied until the target particle size distribution was achieved.

[0290] Tables 1 and 2 detail the formulations studied. In the tables below, the amounts of the ingredients are expressed in grams of raw material.

[0291] Table 1: Table 2: Table 3: *Solvesso 200 ND is a complex mixture of aromatic hydrocarbons, primarily in the form of alkylnaphthalenes produced by petroleum distillation. It is composed of C11–C15 aromatic compounds. More specifically, it contains a large amount of methylnaphthalene, which is naphthalene-depleted. (depleted) solvent.

Visual inspection is performed to detect any signs of instability, such as phase separation, dehydration shrinkage, flocculation, sedimentation, emulsification, or the presence of macroscopic oil droplets on the sample surface. A stable formulation is one that does not exhibit any of these signs of instability after being stored at the considered temperature for the considered time.

[0293] • Viscosity measurement: The viscosity of each emulsion was measured using the following two methods.

[0294] (1) At 20°C, the viscosity of each emulsion A1 to A9 was measured after 1 minute at 20 rpm using a Brookfield RV viscometer (Ametek) equipped with rotors No. 2, 3 or 4.

[0295] (2) A controlled stress rheometer ARG2 (TA Instruments, Surrey, Great Britain) was used, equipped with a rotor-cylinder (diameter: 14 mm; cylinder immersion height: 42 mm) / stator type (diameter: 15 mm, gap: 4 mm) geometry. Ten stress tests were conducted at 20°C. -3 s -1 -200 s -1 The shear rate was scanned at 10 points every decimal harmonics, with a 1-minute stabilization period. The static yield stress value was determined as the shear stress value applied when the viscosity began to decrease.

[0296] • Measurement of droplet size distribution: The droplet size distribution was determined by measuring the particle size using laser diffraction.

[0297] Dilute the EW emulsion with deionized water to a concentration of 1 wt% and stir with a magnetic stirrer for 1 minute. Then transfer the preparation to the measuring cell of a Malvern Mastersizer 2000 or 3000. Adjust the amount of preparation to achieve 10% obscuration (permissible range 8% to 15%).

[0298] The analysis can be performed using the following parameters: Measurement parameters: Sample measurement duration: 10 seconds; Blank measurement duration: 10 seconds; 3 cycles per measurement.

[0299] The calculations were performed using Fraunhofer theory: optical model: [Fraunhofer]; standard analysis, normal sensitivity.

[0300] dv(50) is the median droplet size (micrometers) of the volumetric particle size distribution, which is the droplet size (micrometers) that divides the volumetric distribution into two halves. Similarly, 90% of the volumetric particle distribution is below dv(90), and 10% of the volumetric particle size distribution is below dv(10). The span index represents the distribution width and is defined as: span index = (dv(90) - dv(10)) / dv(50).

[0301] The results are summarized in Tables 4, 5, and 6 below.
