Description

[Technical Field]

[0001] 1. Field of Invention The present invention relates to pesticide compositions. More specifically, the present invention relates to aqueous pesticide compositions comprising an electrolyte pesticide dissolved in an aqueous phase, and to pesticides suspended in an aqueous phase. [Background technology]

[0002] 2. Background of the Invention Pesticides can be formulated as concentrates in various forms, including solid compositions such as wettable powders and granules, as well as liquid compositions such as emulsions. Liquid compositions offer advantages over solid compositions because they are easier to measure and pour, and when diluted with water, they typically leave little to no residue on any equipment used to prepare and apply the pesticide.

[0003] For pesticides that are insoluble or not sufficiently soluble in water, liquid compositions are typically prepared by dissolving the pesticide in an organic, water-immiscible solvent, such as an aromatic hydrocarbon or a more polar ester solvent. However, the use of organic solvents in the preparation of liquid compositions is often undesirable both ecologically and from a human safety standpoint. Therefore, it is preferable to minimize the amount of organic solvent in liquid pesticide compositions whenever possible. In addition, many pesticides are electrolytes, which are water-soluble but whose solubility in organic solvents is insufficient to allow for the formulation of organic solutions.

[0004] Aqueous liquid compositions of pesticides can be prepared. In the case of water-soluble pesticides, the pesticide can be dissolved in the aqueous phase. If the pesticide is not soluble in water, it can be suspended as solid particles or liquid droplets (e.g., oil-in-water emulsions). To suspend particles or droplets, it is necessary to incorporate some anti-settling system, typically a water-swellable clay (e.g., attapulgite) or a water-soluble polymer (e.g., xanthan gum). The inventors have found that structured surfactants (i.e., a surfactant phase that imparts anti-settling properties to the aqueous phase) can be used to suspend particles and droplets. An advantage of using structured surfactants to suspend pesticides is that the surfactant can also act as an adjuvant. Surfactants as adjuvants are often employed in pesticides either by being incorporated into the pesticide formulation or as components that are “tank-mixed” with the pesticide before application to improve the biological efficacy of the pesticide when applied. “Built-in” adjuvants in formulations can also reduce storage and transport costs. If it is desirable for the liquid composition to contain more than one type of pesticide, one or more pesticides can be dissolved in the aqueous phase, or one or more pesticides can be suspended in the aqueous phase. [Overview of the project] [Problems that the invention aims to solve]

[0005] In the case of aqueous liquid compositions, problems arise when it is required to contain both suspended pesticides and electrolyte pesticides. The inventors have found that electrolyte pesticides tend to cause significantly reduced effectiveness as anti-settling aids when suspended in conventional clay or polymers, and that the increase in suspension capacity decreases as the concentration of dissolved electrolyte increases. The inventors have found that some surfactant combinations can produce a suspension structure at low electrolyte concentrations (e.g., 10% by weight of electrolyte), but this does not work well when high concentrations of electrolyte pesticides are used. Therefore, the object of the present invention is to solve this problem and further enable the application of relatively high concentrations of electrolyte pesticides while simultaneously suspending other pesticides therein. The objective is to provide an aqueous pesticide composition that enables excellent suspension and pourability of the liquid formulation over the temperature range required for storage (typically -10°C to 40°C). By selecting a suitable surfactant, it is expected that the ability to combine high concentrations of dissolved electrolyte pesticides with suspended solid or liquid pesticides in the presence of the surfactant will be advantageous. The combination of pesticides can impart additional properties to each individual pesticide, and the high concentrations can reduce packaging and transportation costs. Incorporating surfactants to suspend solid or liquid pesticide particles eliminates the need for other anti-settling agents, which offer little benefit to the biological efficacy of the product when applied. [Means for solving the problem]

[0006] 3. Summary of the Invention The inventors have discovered a surfactant system that can suspend pesticides in water and impart excellent ease of injection over the temperature range required for storage (-10°C to 40°C), even in the presence of 20% by weight or more of the dissolved electrolyte pesticide based on the total weight of water in the composition.

[0007] In one embodiment, the present invention is (i) Water in an amount of 30% by weight or more based on the total weight of the liquid pesticide composition: (ii) One or more electrolyte pesticides dissolved in water, wherein the total amount of electrolyte pesticides dissolved in water is 20% by weight or more based on the total weight of water in the liquid pesticide composition; (iii) A surfactant system, (a) alkyl polyglucoside surfactants, alkyl glucamide ester surfactants and / or ethoxylated aliphatic alcohol phosphate surfactants; and (b) an auxiliary surfactant comprising an anionic head group and a tail group, wherein the tail group comprises at least two alkyl, alkenyl, or alkynyl groups.

[0008] In another embodiment, the present invention relates to the use of the surfactant system of the present invention for suspending an electrolyte pesticide in an aqueous composition containing an electrolyte pesticide, wherein the total amount of the electrolyte pesticide dissolved in water is 20% by weight or more based on the total weight of water in the liquid pesticide composition, and the surfactant system comprises (a) an alkyl polyglucoside surfactant, an alkyl glucamide ester surfactant and / or an ethoxylated aliphatic alcohol phosphate ester surfactant; and (b) an auxiliary surfactant comprising an anionic head group and a tail group, wherein the tail group comprises at least two alkyl, alkenyl or alkynyl groups. [Modes for carrying out the invention]

Description of the Invention 4.1 Overview As used herein, the terms “contains,” “contains,” “examples,” “cited,” “has,” “has,” or any other variations thereof are intended to encompass non-exclusive inclusion. For example, a composition containing the listed components is not necessarily limited to those components alone, and may also contain other components not expressly listed or specific to such a composition. Nevertheless, the terms “contains,” “contains,” “examples,” “cited,” “has,” “has,” or any other variations thereof also encompass disclosed embodiments that do not have any other additional components (i.e., consist of those components).

[0010] Furthermore, the indefinite articles "a" and "an" precede the elements or components of the present invention. The term "a" is intended to be non-restrictive with respect to the number of examples (i.e., occurrences) of an element or component. Therefore, "a" or "an" means one or at least It should be read as including one, and unless the number clearly means singular, the singular form of an element or component also includes the plural form.

[0011] Furthermore, wherever an embodiment of the present invention is described as "preferred," it should be understood that such preferred embodiment may be combined with other preferred embodiments of the present invention described herein, in accordance with the appended claims.

[0012] 4.2 Liquid composition The pesticide compositions of the present invention are liquids. The term “liquid” is used throughout this disclosure to mean that the composition or component in question is in liquid form at standard temperature and standard pressure. Liquid pesticide compositions are well known in the art. For examples of such, see “Catalogue of pesticide formulation types and international coding system,” Technical Monograph No. 2, 7th edition, revised March 2017, CropLife International. Any of the liquid compositions disclosed therein, in which at least one pesticide is dissolved in an aqueous phase and at least one pesticide is suspended in an aqueous phase, can be used in the present invention. As an example, the liquid composition can take the form of a capsule suspension (CS), an oil-in-water emulsion (EW), a suspension concentrate (SC), a suspension concentrate for direct application (SD), a suspo-emulsion (SE), a mixed formulation of CS and SE (ZE), or a mixed formulation of CS and EW (ZW).

[0013] The liquid composition of the present invention is aqueous. "Aqueous" means that water is present as a continuous phase of the composition. Other water-miscible liquid solvents may be present, provided that their combined weight is less than the total weight of water in the composition. Preferably, the mixture of water and such water-miscible liquid solvent contains 60% by weight or more of water, more preferably 70% by weight or more of water, even more preferably 80% by weight or more of water, and even more preferably 90% by weight or more of water, based on the combined weight of water and water-miscible liquid solvent. In another embodiment, the composition contains 20% by weight or less of a water-miscible solvent other than water in the continuous phase, more preferably 10% by weight or less, and even more preferably 5% by weight or less of such water-miscible solvent, based on the combined weight of water and water-miscible liquid solvent. In a preferred embodiment, water is the only solvent used in the continuous phase of the composition.

[0014] The total amount of water present in the composition is 30% by weight or more, preferably 35% by weight or more, and most preferably 40% by weight or more, based on the total weight of the liquid pesticide composition. Water is present in the composition in an amount of preferably 75% by weight or less, more preferably 70% by weight or less, even more preferably 65% ​​by weight or less, more preferably 60% by weight or less, and most preferably 50% by weight or less, based on the total weight of the liquid pesticide composition. Any of the lower weight percentage values ​​can be combined with any of the upper weight percentage values ​​to provide a preferred range for the amount of water in the composition. Preferred ranges include 30-75% by weight, 35-70% by weight, 35-65% by weight, 40-60% by weight, and 40-50% by weight.

[0015] (ii) Electrolyte pesticides dissolved in water The term “electrolyte pesticide” means a pesticide that is expected to form ions when dissolved in water at 20°C. The term “pesticide” as used herein (including in the case of suspended pesticides as described below) means any chemical substance that can kill, repel, or prevent the growth or reproduction of unwanted organisms (“harmful organisms”), or any chemical substance that can protect or promote the healthy growth or reproduction of desired organisms such as crops, ornamental plants, livestock and domestic animals, as well as any chemical substance that is useful in agriculture, horticulture, forestry, animal husbandry, water treatment and land management, such as land management with respect to application to the ground, crops, orchards, livestock, gardens, woodlands, rows of shrubs, parks, industrial sites, construction sites, airports, roads, railways, rivers, lakes, ponds, canals, irrigation and drainage work.

[0016] The electrolyte pesticide may be an insecticide, such as a herbicide, fungicide, or insecticide. The electrolyte pesticide may also be a plant growth regulator or a fertilizer, such as a water-soluble inorganic fertilizer or a water-soluble organic fertilizer. With respect to the object of the present invention, the electrolyte pesticide is preferably a herbicide.

[0017] In the present invention, one or more electrolyte pesticides are dissolved in water contained in the liquid pesticide composition. The total amount of electrolyte pesticides dissolved in water is 20% by weight or more, based on the total weight of water in the liquid pesticide composition. One advantage of the present invention is that the liquid composition can accommodate a larger amount of electrolyte pesticides while still providing a stable, structured surfactant system for suspending other pesticides. For economic reasons (e.g., reduced packaging; reduced storage and transport costs), the total amount of electrolyte pesticides can be close to saturation, so that the electrolyte pesticides are the highest concentration material in the formulation. If the composition is to be stored and / or used at low temperatures, appropriate consideration of a lower limit of saturation at such temperatures should be taken into account to avoid undesirable precipitation. The total amount of electrolyte pesticides dissolved in water is preferably 30% by weight or more (based on the total weight of water in the liquid pesticide composition), and may be present in amounts of 40% by weight or more, 50% by weight or more, or 60% by weight or more. The upper limit of the total amount of electrolyte pesticide dissolved in water is limited only by the amount of pesticide that the water can dissolve in the system in question. The total amount of electrolyte pesticide dissolved in water is preferably 100% by weight or less (based on the total weight of water in the liquid pesticide composition) and may be 90% by weight or less, 80% by weight or less, or 70% by weight or less. Any of the lower weight percentage values ​​can be combined with any of the upper weight percentage values ​​to provide a preferred range of total amounts of electrolyte pesticide based on the total weight of water in the liquid pesticide composition. Exemplary ranges include 30-100% by weight, 40-90% by weight, 40-80% by weight, 30-60% by weight, and 40-60% by weight. The above weight percentage amounts refer to the electrolyte pesticide itself and not to any other entities that may be associated with it (e.g., bases). For example, if glyphosate is added as glyphosate potassium, the above weight percentage amounts refer to glyphosate and not to the glyphosate potassium salt.

[0018] Examples of water-soluble herbicides that constitute the electrolyte solution in water include those listed in the Pesticide Manual (British Crop Protection Council; 16th edition). Examples of herbicides include asifluorphen sodium, aminopyralide-triisopropanolammonium, amitorol, ammonium sulfamate, asharam sodium, bentazon sodium, bilanifos sodium, bispyrabac sodium, sodium metaborate, bromacyl lithium, and bromoxynil.

Preferred water-soluble electrolyte herbicides are selected from the following enumeration: 2,4-D-dimethylammonium; 2,4-D-triethanolammonium; 2,4-D-triisopropylammonium; 2,4-DB-dimethylammonium; 2,4-DB-sodium and potassium; dicambadiglycolamine salts; dicambadimethylammonium; dicambadiethanolammonium; dicambaisopropylammonium; dicambapotassium; dicambasodium; dicambatriethanolammonium; glufosinateammonium; glyphosateisopropylammonium; glyphosatepotassium; glyphosatesesquisodium; glyphosatediammonium; glyphosatedimethylammonium; glyphosateammonium; MCPA sodium; MCPA potassium; MCPA dimethylammonium; MCPB sodium; MCPB potassium; dichlorprop-potassium; dichlorprop-P-dimethylammonium; dichlorprop-P-potassium; and dichlorprop-P-sodium.

[0019] The most preferred water-soluble electrolyte herbicides are glyphosate (N-(phosphonomethyl)glycine), glufosinate ((RS)-2-amino-4-(hydroxy(methyl)phosphonoyl)-butanoic acid), 2,4-D((2,4-dichlorophenoxy)acetic acid), and dicamba (3,6-dichloro-2-methoxybenzoic acid), as well as their phytochemically acceptable salts. Glyphosate-type herbicides, which are well known and widely used and have a broad antimicrobial spectrum, are N-phosphonomethyl-N-carboxyalkyl compounds, particularly N-phosphonomethylglycine, which are usually available as water-soluble phytochemically acceptable salts, and are generally available as alkali metal salts, such as sodium or potassium or trimethylsulfonium, isopropylamine, ammonium, diammonium, dimethylamine, or triethanolamine salts. Glufosinate-type herbicides are phosphinylic amino acids, such as glufosinate [2-amino-4-(hydroxymethylphosphinyl)butanoic acid], and are particularly useful as ammonium salts. For both glyphosate and glufosinate-type herbicides, the main active ingredient is present in aqueous solution as an anion (or an amphoteric ion having a negative charge as a whole). 2,4-D can be used as its dimethylamine or choline salt, and dicamba can be used as its diglycolamine, dimethlyammonium, isopropylamine, potassium, or sodium salt. When the electrolyte pesticide is glyphosate or a salt thereof, it is preferably present in the composition in an amount of 20-40% by weight of glyphosate based on the total weight of the composition.

[0023] Compounds containing other water-soluble nutrients (generally identified as "micronutrients") may also be included in the composition, for example, to provide small or trace amounts of nutrients to the formulation. Similarly, some or all of the electrolyte components of the formulation may include water-soluble buffers and chelating agents, such as ammonium citrate and alkali metal citrates, glucons, lactates, and polyacrylates.

[0024] In the present invention, combinations of water-soluble electrolyte pesticides with other water-soluble electrolyte pesticides are possible, and combinations of herbicides with other herbicides, fungicides with other fungicides, and plant growth regulators with other plant growth regulators are preferred. Suitable herbicide combinations include asifluorphen-sodium and bentazone-sodium; clopyralido potassium and MCPA potassium; 2,4-D-dimethylammonium and MCPA dimethylammonium; 2,4-D-triethanolammonium and MCPA sodium; and 2,4-D-triisopropyl Ammonium and MCPA potassium; 2,4-DB sodium and MCPA sodium and / or MCPA potassium; 2,4-DB potassium and MCPA sodium and / or MCPA potassium; dicamba potassium and glyphosate potassium; diflufenzopyr sodium and dicamba sodium; glufosinate ammonium and MCPA salt, e.g., MCPA sodium or MCPA potassium; glufosinate ammonium and dicamba isopropylammonium; dicamba digesticlycolamine salt and glyphosate diammonium; dicamba triethanolammonium and glyphosate isopropylammonium; dicamba dimethylammonium and glyphosate dimethylammonium; dicamba diethanolammonium and glyphosate diammonium; dicamba sodium and glyphosate sodium; dichlorprop-P-dimethylammonium and MCPA dimethylammonium; glyphosate isopropyl Examples include propylammonium or glyphosate-isopropylamine and glufosinate-ammonium; imazaquin-ammonium and chlormecote chloride; ioxinyl-sodium and mecoprop-sodium and / or MCPA dimethylammonium; MCPA sodium and other MCPA salts (e.g., MCPA potassium or MCPA dimethylammonium), 2,4-DB potassium, and / or 2,4-DB sodium; MCPA potassium and other MCPA salts (e.g., MCPA sodium), 2,4-DB potassium, and / or 2,4-DB sodium; MCPA dimethylammonium and other MCPA salts (e.g., MCPA sodium or MCPA potassium); MCPB-sodium and MCPB-potassium; 2,4-DB dimethylammonium, and / or ioxinyl-sodium; mecoprop-P dimethylammonium and dichloroprop-P-dimethylammonium and / or MCPA dimethylammonium.

[0026] (iii) Surfactant-based The composition comprises a surfactant system that forms vesicles, preferably multilayer vesicles (spherulites), in the aqueous phase. These vesicles enable the suspension of pesticides in the composition by forming a dense structure that yields a liquid having the rheological properties necessary for suspending solid particles or liquid droplets. The surfactant system comprises (a) alkyl polyglucoside surfactants, alkyl glucamide ester surfactants and / or ethoxylated aliphatic alcohol phosphate ester surfactants. The surfactant system further comprises (b) auxiliary surfactants having an anionic head group and tail group, wherein the tail group has at least two alkyl, alkenyl, or alkynyl groups. The present invention is based on the surprising discovery that surfactant systems based on a combination of (a) alkyl polyglucoside surfactants, alkyl glucamide ester surfactants and / or ethoxylated aliphatic alcohol phosphate ester surfactants, and (b) auxiliary surfactants having an anionic head group and a tail group having at least two alkyl, alkenyl or alkynyl groups, are expected to enable vesicle formation in the presence of large amounts of electrolyte pesticides, and furthermore, that these vesicles can suspend solid particles and liquid droplets over a wide temperature range, typically from -10°C to 40°C when stored.

[0027] In prior art surfactant systems, typically, when dissolving a large amount of electrolytic pesticide in an aqueous system, surfactants are combined in a way that allows other components, such as a second pesticide, to be suspended. This becomes difficult, if not impossible. In the presence of a large amount of electrolyte, in most surfactant combinations, the surfactant combination is either entirely or partially insoluble and separates from the aqueous solution during storage, or the surfactant combination becomes completely soluble and forms a micelle solution, but the micelle solution cannot suspend particles.

[0028] For example, US2010 / 0160168A1 describes homogeneous liquid pesticide concentrates. The surfactant system used therein forms microemulsions (and thus homogeneity), which are not structured surfactant systems and cannot suspend solids, for example, in the composition. US10,091,994B2 describes a surfactant, and its salt is reported to retain surfactant activity while avoiding gelation problems in formulations. This document does not indicate whether the surfactant system can be used to suspend solids, for example, in aqueous formulations containing relatively large amounts of electrolyte pesticides.

[0029] Furthermore, the problems discussed above, and the problems in the prior art mentioned immediately prior to this, are overcome by using a surfactant system according to the present invention based on a combination of auxiliary surfactants, which is (a) alkyl polyglucoside surfactants, alkyl glucamide ester surfactants and / or ethoxylated aliphatic alcohol phosphate ester surfactants, and (b) auxiliary surfactants comprising an anionic head group and tail group, wherein the tail group comprises at least two alkyl, alkenyl, or alkynyl groups. The present invention is also advantageous in that the surfactants used are environmentally friendly, unlike surfactants used in the prior art, such as cationic hexadecylammonium chloride.

[0030] (a-1) Alkyl polyglucoside surfactant Alkyl polyglucosides are the basis of substances consisting of a chain of sugar rings linked together by glucosidic bonds, where the last ring of the glucosidic chain is acetalized with an alcohol.

[0101] 4.3 Preparation method The liquid pesticide compositions of the present invention can be prepared by known processes, for example, by first preparing a mill base and a solution base of a particular component, and then combining both by blending, as will be described in more detail later. Insofar as the final composition contains the aforementioned alkyl polyglucoside surfactant, alkyl glucamide ester surfactant and / or ethoxylated aliphatic alcohol phosphate ester surfactant (a) and an auxiliary surfactant (b) comprising an anionic head group and a tail group, wherein the tail group comprises at least two alkyl, alkenyl or alkynyl groups, vesicles are formed, and thus suspensions of two or more pesticide solutions are formed.

[0117] 6. Examples ■Experimental Example 1: Testing of various surfactants as auxiliary surfactants (b) with alkyl polyglucoside surfactants (a) Agricultural chemical compositions containing various test surfactants as auxiliary surfactants (b) to alkyl polyglucoside surfactants (a) were prepared and tested for stability.

[0118] Preparation of mill base Because they are substantially water-insoluble, algicides and the herbicide diuron((3-(3,4-dichlorophenyl)-1,1-dimethylurea) were selected as representative of a general class of pesticides that can be suspended according to the present invention.

[0119] Water (48.98 wt%), Silcolapse® 426R (0.82 wt%), Agnicke® PG-8107G (6.27 wt%), and Diuron (43.93 wt%) were added together and blended using a Silverson high-shear mixer with a small-hole head set to 3000 rpm. Agnicke (Registered Trademark) PG-8107G (BASF AG) is one of the surfactants required for this invention. This is a representative alkyl polyglucoside. Silcolaps® 426R (Bluestar Silicones) is an antifoaming agent and is added during preparation to further reduce foaming throughout the experiment. The resulting slurry was bead-milled in an Eiger mill at 3000 rpm for approximately 40 minutes using 1-1.3 mm beads. The final particle size of diuron (D50: 1.9 μm; D90: 4.7 μm) was typical for use in suspensions of pesticide particles in aqueous formulations. Microscopic observation confirmed that the particles were well dispersed in the mill base.

[0120] Solution-based preparation Because it is a water-soluble electrolyte, glyphosate, a herbicide, was selected as a representative example of a general class of electrolyte pesticides that can be dissolved in the aqueous phase according to the present invention.

[0121] Water (36.47 wt%), Silcolaps® 426R (0.10 wt%), Agnike® PG-8107G (5.66 wt%), and 83.7% KOH (16.39 wt%) were added together and stirred in an overhead mixer equipped with a propeller stirrer. Glyphosate (41.38 wt%) was slowly added to the KOH solution and stirred for at least 1 hour until neutralization and dissolution were completely achieved.

[0122] Preparation of pesticide compositions for testing The pesticide composition was prepared by blending the above-mentioned mill base (21.48% by weight), water (2.57% by weight), the surfactant to be tested (14.53% by weight, a 30% aqueous solution of the surfactant), and the above-mentioned solution base (61.42% by weight). After blending, an electrolyte pesticide (glyphosate) was dissolved in the aqueous phase, and another pesticide (diuron) was suspended in the aqueous phase to obtain a pesticide composition. The relative amounts of the different components in the composition were as follows:

[0123] [Table 1-1]

[0124] The compositions were stored at 20°C for one week, and then visually inspected for stability. The table below shows the results for each different composition containing different test surfactants. The degree of separation is an estimate based on the amount of clear solution separated from compositions that were opaque under other conditions.

[0125] [Table 1-2]

[0126] Regarding the experiment of the present invention, the excellent ease of injection was achieved in 20 seconds. -1 It was defined as <500 mPa·seconds. Poor injectability was 20 seconds - 1 It is defined as >1000 mPa·seconds in that context.

[0127] As is evident from the data in the table above, not all surfactants necessarily function synergistically with alkyl polyglucosides to provide an injectable composition that is stable in the presence of a substantial amount of electrolyte pesticide. For example, nonionic surfactants typically used in pesticide compositions, such as alkoxylated aliphatic alcohols (Symperonic® A2; Symperonic® 13 / 6.5) and alkoxylated aliphatic amines (Adcy® AB615), as well as cationic surfactants, such as those based on quaternary ammonium (Alquad® 16-29), resulted in compositions exhibiting significant separation. Amphoteric (Ammonics® LO) or amphoteric (Empigen® BB) surfactants were also unsatisfactory. Although somewhat more stable than nonionic and cationic surfactants, they nevertheless exhibited significant separation and poor injectability.

[0128] From the data above, it can be seen that surfactants that yield injectable compositions with little separation during storage share common characteristics. Firstly, these are all anionic surfactants having at least two hydrocarbon chains. Anionic surfactants with only one hydrocarbon chain resulted in compositions that were either injectable (Empicol® LZ) or exhibited poor injectability and significant separation (Steol® CS270). Simply having two hydrocarbon chains is not sufficient for a surfactant. Surfactants with two hydrocarbon chains but that are not anionic resulted in compositions that were either injectable (Polyald® 6-2-6) or exhibited poor injectability and / or significant separation (Polyald® 10-2-P; Polyald® 10-10-O).

[0129] ■Experiment Example 2: Increasing the amount of electrolyte pesticide Pesticide compositions were prepared using significantly larger amounts of electrolyte pesticides and tested for stability under different conditions. The following table provides a summary of the compositions and test results.

[0130] [Table 2]

[0131] As can be seen from the data above, the surfactant combination according to the present invention provides a stable pesticide composition under various test conditions. After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. 1 It is defined as <500 mPa·seconds in that region.

[0132] ■Experimental Example 3: Use of a mixture of auxiliary surfactants A pesticide composition was prepared using a mixture of surfactants according to the auxiliary invention. The following table provides a summary of the composition and test results.

[0133] [Table 3]

[0134] As can be seen from the data above, the surfactant combination according to the present invention provides a stable pesticide composition under various test conditions. After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. -1 It is defined as <500 mPa·seconds in that region.

[0135] ■Experimental Example 4: Reducing the amount of auxiliary surfactant (b) A pesticide composition with reduced amounts of auxiliary surfactants was prepared. The following table provides a summary of the composition and test results.

[0136] [Table 4]

[0137] As the data above shows, reducing the amount of auxiliary surfactants still provides a stable pesticide composition under various test conditions. After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. -1 It is defined as <500 mPa·seconds in that region.

[0138] ■Experimental Example 5: Using a mixture of the surfactant according to the auxiliary invention and another surfactant A pesticide composition was prepared using a mixture of the surfactant according to the auxiliary invention and another surfactant. The following table provides a summary of the composition and test results.

[0139] [Table 5]

[0140] As can be seen from the data above, surfactants such as alkylethoxy2EO sulfate sodium (from Steol® CS270) were not sufficient on their own to provide a stable composition with alkyl polyglucosides (see Experimental Example 1), but they can still be added to the composition when an auxiliary surfactant according to the present invention is present.

[0141] ■Experimental Example 6 (Reference Example): Use of the auxiliary surfactant of the present invention together with a betaine surfactant This example tests whether stability can be maintained when an alkyl polyglucoside surfactant is replaced with a surfactant that is tolerant to a different electrolyte. In this example, the alkyl polyglucoside surfactant from the previous example was replaced with a betaine surfactant (Empigen® BS). Betaine is a class of surfactants that is considered to have greater electrolyte tolerance than ethoxylated surfactants, anionic surfactants, and cationic surfactants, considering that betaine is relatively less likely to precipitate from high-electrolyte compositions compared to these other surfactants.

[0142] Preparation of mill base Water (21.75% by weight), Silcolaps® 426R (0.82% by weight), E Npigen® BS (33.50 wt% 30% aqueous solution) and Diuron (43.93 wt%) were added together and blended using a Silverson high-shear mixer with a small-hole head set to 3000 rpm. The resulting slurry was bead-milled in an Eiger mill using 1-1.3 mm beads at 3000 rpm for approximately 13 minutes. The final particle size of Diuron (D50: 2.2 μm; D90: 5.1 μm) is typical for suspension of pesticide particles in aqueous formulations, and these particles were well dispersed in the mill base (as observed by microscopy).

[0143] Solution-based preparation Water (35.53 wt%), Silcolaps® 426R (0.10 wt%), a 30% aqueous solution of Empigen® BS (6.60 wt%), and 83.7% KOH (16.39 wt%) were added together and stirred in an overhead mixer equipped with a propeller stirrer. Glyphosate (41.38 wt%) was slowly added to the KOH solution and stirred for at least 1 hour until neutralization and dissolution were completely achieved.

[0144] Preparation of pesticide compositions for testing The pesticide composition was prepared by blending the above-mentioned mill base (21.48% by weight), water (2.57% by weight), Nansa® HS80S (14.53% by weight, a 30% aqueous solution of surfactant), and the above-mentioned solution base (61.42% by weight). After blending, the following pesticide composition was obtained:

[0145] [Table 6]

[0146] The composition was stored at 20°C for one week, and then visually inspected for stability, which estimated that 40% separation had occurred. This data was compared to the corresponding composition in Experiment Example 1 using sodium dodecylbenzenesulfonate (from Nansa® HS80S) at 20°C. Compared to stability over one week (<1% separation), it is clear that the auxiliary surfactant of the present invention functions synergistically with the alkyl polyglucoside surfactant to provide a stable composition even in the presence of electrolyte pesticides.

[0147] ■Experimental Example 7: Changing the ratio of alkyl polyglucoside to auxiliary surfactant Agricultural chemical compositions were prepared by varying the relative amounts of alkyl polyglucoside surfactants and auxiliary surfactants. The following table provides a summary of the compositions and test results.

[0148] [Table 7]

[0149] In this experiment, the total amount of alkyl polyglucoside surfactants and auxiliary surfactants was kept constant (7.50 wt%), but their relative amounts were varied. All samples were stable and had at least acceptable or excellent injectability. Excellent injectability was measured in 20 seconds. -1 Defined as <500 mPa·seconds, the acceptable ease of injection is 20 seconds. -1 It is defined as 500-1000 mPa·s in that region.

[0150] ■Experimental Example 8: Test of the present invention compared with a typical prior art system that relies on xanthan gum for pesticide suspension. The pesticide compositions were mostly prepared according to Experimental Example 1. The following table shows the compositions and test results. This provides a summary of the findings. A composition containing xanthan gum (Kelzan AP-AS) was designed to have a viscosity as close as possible to that of the composition of the present invention before being sent to storage.

[0151] [Table 8]

[0152] The composition of the present invention exhibited excellent stability and ease of injection under all storage conditions. Excellent ease of injection was achieved in 20 seconds. -1It is defined as <500 mPa·seconds. Compositions containing xanthan gum showed significant separation at 20°C and 40°C, and poor injectability at -10°C.

[0153] ■Experiment Example 9: Changing the electrolyte pesticide A pesticide composition was prepared using glufosinate ammonium instead of glyphosate. The following table provides a summary of the composition and test results.

[0154] [Table 9]

[0155] As can be seen from the data above, the surfactant combination according to the present invention provides a stable pesticide composition under various test conditions for different electrolyte pesticides (in this case, glufosinate ammonium). After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. -1 It is defined as <500 mPa·seconds in that region.

[0156] ■Experimental Example 10: Composition using alkylglucamide ester as auxiliary surfactant (a) A pesticide composition was prepared, using an alkylglucamide ester instead of an alkyl polyglucoside as the auxiliary surfactant (a). The following table provides a summary of the composition and test results.

[0157] [Table 10]

[0158] Alkyl glucamides are a class of surfactants that have been found to have greater tolerance to electrolytes than nonionic ethoxylated surfactants, ethoxylated anionic surfactants, nonethoxylated anionic surfactants, and cationic surfactants, considering that they are relatively less likely to precipitate from high-electrolyte compositions compared to these other surfactants.

[0159] The same mill base prepared in Experimental Example 1, and therefore trace amounts of alkyl polyglucoside, were used. A concentrated glyphosate solution containing C8,C10-alkyl sugar amide (i.e., glucamide in Synagen GA) was prepared. In the presence of dissolved glyphosate, the glucamide and isopropylamine LABS formed a structure capable of suspending the milled diuron particles.

[0160] As can be seen from the data above, the pesticide composition is stable under various test conditions. After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. -1 It is defined as <500 mPa·seconds in that region.

[0161] ■Experimental Example 11: Composition using an ethoxylated aliphatic alcohol phosphate surfactant as auxiliary surfactant (a) A pesticide composition was prepared, but instead of alkyl polyglucoside as auxiliary surfactant (a) Ethoxylated aliphatic alcohol phosphate surfactants were used. The following table provides a summary of the compositions and test results.

[0162] [Table 11]

[0163] Ethoxylated aliphatic alcohol phosphate esters are a class of surfactants that have been found to have greater tolerance to electrolytes than nonionic ethoxylated surfactants, nonethoxylated anionic surfactants, and cationic surfactants, considering that they are relatively less likely to precipitate from high-electrolyte compositions compared to these other surfactants.

[0164] The same mill base prepared in Experimental Example 1, and therefore trace amounts of alkyl polyglucoside, were used. A concentrated glyphosate solution containing C10 EO4 phosphate (i.e., the phosphate ester in multitrope 1214) was prepared. In the presence of dissolved glyphosate, the ethoxylated aliphatic alcohol phosphate ester and isopropylamine LABS formed structures capable of suspending the milled diuron particles.

[0165] As can be seen from the data above, the pesticide composition is stable under various test conditions. After storage, all samples were stable and showed excellent ease of injection. Excellent ease of injection was observed in 20 seconds. -1 It is defined as <500 mPa·seconds in that region.

[0166] ■Example 12 (Reference Example): Composition using an amine oxide surfactant as an auxiliary surfactant (a) This experimental example tests whether auxiliary surfactant (a) of the present invention can be replaced with another surfactant (alkyldimethylamine oxide) that is considered in the industry to have the same electrolyte tolerance as alkyl polyglucoside. A pesticide composition was prepared, but alkyldimethylamine oxide was used instead of alkyl polyglucoside as auxiliary surfactant (a). The following table provides a summary of the composition and test results.
