Description

[Technical Field]

[0001] This disclosure relates to a liquid pesticide composition containing an electrolytic pesticide as an active ingredient, a process for preparing the liquid pesticide composition, and a method for controlling weeds using the liquid pesticide composition. [Background technology]

[0002] Water-soluble herbicides used as non-selective foliar herbicides are widely used and effective crop protectants. For example, U.S. Patent No. 4,168,963 discloses 2-amino-4-[hydroxy(methyl)phosphinoyl]butyric acid (glufosinate). Salts and isomers of glufosinate have good and broad activity against weeds of many plant species. Glufosinate is a non-selective contact herbicide with several systemic effects. When glufosinate is applied to weeds, glutamine levels in the weed tissue decrease, ammonia levels increase, photosynthesis stops, and the weed plants die.

[0003] The L-enantiomer of glufosinate is considered a biologically active isomer. The herbicidal activity of the L-isomer is twice that of the racemic mixture, and the use of the L-isomer offers clear advantages such as reduced application rates and fewer side effects.

[0004] Glufosinate is used to control persistent weeds such as morning glory, hemlock sesbania (Sesbania bispinosa), Pennsylvania smartweed (Polygonum pensylvanicum), and yellow nut edulis.

[0005] Glufosinate is most frequently used as a directional spray for weed control in crops, including genetically modified crops, and as a crop desiccant to facilitate harvesting.

[0006] In the case of water-soluble herbicides such as glufosinate, the properties and amount of adjuvants mixed with glufosinate can affect the activity of the mixture.

[0007] For example, there is still a need to find a suitable adjuvant that effectively enhances the performance of a pesticide composition containing glufosinate and / or L-glufosinate.

[0009] Yet another object of the present disclosure is to provide a highly effective liquid pesticide composition having a specific dynamic surface tension (DST).

[0010] Yet another object of the present disclosure is to provide the use of an effective liquid pesticide composition having a specific DST for weed control.

[0021] In any aspect or embodiment described below in this specification, the phrase "includes," "consists of," "essentially consists of," or "substantially consists of." In these aspects or embodiments, the compositions described contain or have, or consist of, essentially consist of, or substantially consist of, the specific components listed therein, excluding other components or excipients not specifically listed therein.

[0023] "Alkyl" refers to a linear or branched saturated aliphatic hydrocarbon having a specified number of carbon atoms, specifically 1 to 12 carbon atoms, and more specifically 1 to 6 carbon atoms. Alkyl groups include, for example, groups having 1 to 50 carbon atoms (C1 to C50 alkyl groups).

[0024] "Aryl" means a cyclic moiety in which all ring members are carbon and at least one ring is aromatic, having a specified number of carbon atoms, specifically 6 to 24 carbon atoms, more specifically 6 to 12 carbon atoms. There may be two or more rings, and any additional rings may independently be aromatic, saturated or partially unsaturated, and may be condensed, pendanted, spirocyclic, or a combination thereof.

[0025] "Alkylene" refers to a straight-chain or branched-chain saturated divalent aliphatic hydrocarbon group (e.g., methylene (-CH2-) or propylene (-(CH2)3-)).

[0026] When used throughout this disclosure, electrolytic pesticides or other active ingredients include their salts, esters, ethers, isomers, and polymorphs such as solvates and hydrates. Salts include salts that retain the biological efficacy and properties of the active ingredient and are not biologically or otherwise undesirable, and include derivatives of disclosed compounds in which the parent compound is modified to produce its inorganic and organic non-toxic acid or base addition salts. Salts can be synthesized from parent compounds by conventional chemical methods. "Solvate" means a herbicide or an agriculturally acceptable salt thereof in which molecules of a suitable solvent are incorporated into the crystal lattice. A suitable solvent is one that is physiologically acceptable at the dose administered. Examples of suitable solvents include ethanol and water. When water is the solvent, its molecules are referred to as a "hydrate." The formation of solvates varies depending on the compound and the solvate. Generally, solvates are formed by dissolving the compound in a suitable solvent and then cooling or isolating the solvate using a poor solvent. Solvates are typically dried or azeotropic under ambient conditions. In one embodiment, the solvate is a hydrate.

[0027] The term "plant" refers to all physical parts of a plant, including seeds, seedlings, young trees, roots, tubers, stems, stalks, branches, leaves, and fruits. The term "plant" includes both transgenic and non-transgenic plants.

[0028] As used herein, the term “habitat” means the place where a plant grows, where plant propagation material for a plant is planted (e.g., placed in the soil), and / or where plant propagation material for a plant is intended to be planted, its vicinity, or an area of ​​land.

[0029] The term "plant propagation material" refers to the reproductive parts of plants (e.g., seeds), plant materials (e.g., cuttings or tubers), roots, fruits, tubers, bulbs, rhizomes, and other parts of plants, germinating plants, and / or seedlings that are transplanted after germination or emergence from the soil. These seedlings may be protected before transplanting by a full immersion treatment / system or a partial immersion treatment / system.

[0030] As used herein, “effective amount” is the amount of an active ingredient (e.g., a disclosed combination) that has a harmful effect on weeds and / or controls weeds in plants. Harmful effects may include weed death (herbicide), prevention of weed growth, blockage of biosynthetic pathways, or a combination thereof.

[0031] As used herein, “agriculturally permissible salt” means salt that is permitted for use in agriculture or horticulture.

[0032] As used herein, the term “electrolytic pesticide” means a pesticide that forms ions when dissolved in water at 20°C. The term “pesticide” refers to an active ingredient that can kill, repel, or inhibit the growth or reproduction of undesirable organisms ("harmful organisms"), or that can protect or promote the healthy growth or reproduction of desirable organisms such as plants (e.g., crops, ornamental plants), and can be used for application to fields, crops, orchards, gardens, forestry, shrublands, parks, industrial parks, construction sites, airports, roads, railways, rivers, lakes, ponds, canals, irrigation and drainage projects. An electrolytic pesticide may be a pesticide, such as a herbicide, fungicide, or insecticide. In this disclosure, an electrolytic pesticide is a herbicide.

[0033] Glufosinate has the chemical name 2-amino-4-[hydroxy(methyl)phosphoryl]butanoic acid. L-glufosinate, also commercially known as glufosinate-P, is an isomer of glufosinate.

[0034] Surprisingly and unexpectedly, a liquid composition comprising an electrolytic pesticide, a non-hydrotropic phosphorus derivative, a surfactant, and a non-surfactant electrolyte was found to yield a composition with the best dynamic surface tension profile and a highly bioactive formulation. Furthermore, a liquid composition comprising an electrolytic pesticide, a non-hydrotropic phosphorus derivative, a surfactant, and a non-surfactant electrolyte was found to pin droplets of the formulation to the plant surface, preventing them from bouncing off and / or rolling off. As used herein, droplet "pinning" involves retaining at least a portion or substantially all of the liquid present in the droplet on the plant surface for a period sufficient to provide the effectiveness of the pesticide (herbicide) present in the formulation.

[0035] Aqueous formulations of water-soluble herbicides such as glufosinate tend to be washed away by rain or may not remain on the leaf surface for a long enough period to be absorbed by plants. For effectiveness, pinning the formulation droplets to the plant surface is crucial to ensure that contact occurs between the herbicide and the plant for a sufficient period to promote wetting and spreading of the droplets on the leaf surface, thereby facilitating the penetration and transfer of the herbicide into the leaves.

[0036] The action of surfactants is a result of their partially hydrophilic and partially hydrophobic nature, which allows them to adsorb to interfaces separating media of different polarities. For example, a liquid film is generally intended to spread across a solid surface or another liquid surface, and this action is generally called "wetting." This occurs spontaneously when the liquid film or droplet has a lower surface tension than the surface it covers. Therefore, by reducing surface tension, surfactants promote wetting.

[0037] Dynamic surface tension (DST) directly affects the quality of wetting, spreading, and adhesion of components to plant surfaces. Dynamic surface tension correlates considerably with the dynamic wetting conditions of plant surfaces in real-world spray environments. The concentration and activity of surfactants are determined not only by how much surface tension decreases, but also by the rate at which diffusion occurs and how quickly wetting occurs. Formulators can improve the movement, wetting, diffusion, and adhesion of formulations by determining the optimal surfactant concentration through the determination of the dynamic critical micelle concentration (CMC), and by selecting a combination of surfactants and additives that provides the best dynamic surface tension profile for their specific applications.

[0038] Surface wetting occurs on a timescale of milliseconds; therefore, the adsorption kinetics of surfactant molecules to plant surfaces are crucial when selecting a combination of surfactants and additives. Contact angle measurement or contact angle hysteresis is another important tool for understanding the effect of surfactants on the surface tension properties of the formulation, as well as on the diffusion and adhesion properties required for the active ingredients. It further predicts the optimal droplet deposition pattern of the formulation on the leaf surface necessary to produce a uniform distribution of the active ingredients, resulting in better performance.

[0039] It was advantageously discovered that highly effective formulations can be achieved when the combination of surfactants and additives, and the final formulation thereof, result in a spray solution having a specific range of DST.

[0040] The inventors have found that a combination of a specific surfactant that yields the formulation and a spray solution having the best dynamic surface tension profile improves wetting of the plant surface, ensuring that the active substance adheres to the plant surface for a longer period and / or is better taken up by the plant, resulting in a highly effective product.

[0041] In relation to this disclosure, the terms “composition” and “formulation” are used interchangeably.

[0048] In this disclosure, the terms dynamic surface tension (DST) or interfacial tension (IFT) refer to a specific surface lifetime or interfacial lifetime value. Surface lifetime is the period from the start of surface formation to the time of observation or measurement. Interfacial lifetime is the period from the start of interface formation to the time of observation or measurement. The time-dependent value is called dynamic surface tension (DST). In the case of liquids containing surfactants, DST differs from static measurements and measurements of equilibrium surface tension values, which are non-time-dependent.

[0145] Examples 1-6, 8-11, and 14-20 are compositions of the present invention according to this disclosure and are shown in Tables 1-5 below. Comparative examples (compositions not according to the present invention) (Comparative Examples 7, 12, 13, and 21) are also shown in Table 6. The processes used to prepare the compositions in Tables 1-6 are described in further detail below.

[0146] Example 1

[0147] [Table 1]

[0148] Preparation process of the composition of Example 1: Mix the required amount of L-glufosinate ammonium with water, propylene glycol, and ethylene glycol monobutyl ether, then add the calculated amount of C 8 / 10 Alkyl glucamide, polyethylene glycol monotridecyl ether phosphate, decylamine oxide, and potassium chloride were added. The resulting mixture was homogenized to obtain a liquid herbicide composition.

[0149] [Table 2]

[0150] The compositions of Examples 2 to 6 were prepared according to the process of Example 1.

[0151] [Table 3]

[0152] The compositions of Examples 8 to 11 were prepared according to the process of Example 1.

[0153] [Table 4]

[0154] Preparation process of compositions in Examples 14-18: The required amounts of L-glufosinate ammonium, propylene glycol, and ethylene glycol monobutyl ether were slowly mixed in a mixing container while stirring to obtain a dispersion. Then, C8~C 10 Alkyl polyglucosides and / or alkyl glucamides, alkyl ether phosphates, C 10 Alkylamine oxide, C 13 ~C 15 Alkylamine oxide and potassium chloride were added to the dispersion. Then, water was added to the resulting mixture, and the mixture was stirred at a temperature of 20-35°C for 90 minutes to obtain a liquid herbicide composition.

[0155] [Table 5]

[0156] The compositions of Examples 19-20 were prepared according to the process of Example 14.

[0157] [Table 6]

[0158] The compositions of Examples 7, 12, 13, and 21 were prepared according to the process of Example 1.

[0159] Measurement of Dynamic Surface Tension (DST) The dynamic surface tension (DST) of the samples in the examples and comparative examples was determined by the foam pressure method using a foam pressure tensile meter, Model BP100 (KRUSS), for a period of 20 to 50 milliseconds (surface lifetime or foam lifetime) corresponding to the spraying of pesticides in aqueous dilutions. Samples of the above formulations for analysis were prepared by diluting the formulations in water at concentrations of L-glufosinate ammonium at 150 to 400 grams of active ingredient per hectare (g ai / h) and glufosinate ammonium at 300 to 900 g of active ingredient per hectare. Dynamic surface tension was measured from the foam lifetime of 20 to 50 milliseconds at room temperature (25 ± 2°C) and relative humidity (rH) = 65 to 75%.

[0160] Tables 7 and 8 below summarize the DSTs of the example formulations. The spray compositions corresponding to the samples used in the tests are shown in parentheses in the table. Table 8 shows the DSTs of the comparative compositions (compositions not according to the present invention).

[0161] [Table 7]

[0162] [Table 8]

[0163] [Table 9]

[0164] From the above results, it is clear that spray dilutions of formulations of L-glufosinate ammonium containing a combination of a non-hydrotropic phosphorus derivative such as an alkyl ether phosphate, a surfactant (e.g., alkyldimethylamine oxide), and an alkali metal salt have a dynamic surface tension of less than 60 mN / m over a foam surface lifetime of 20 to 50 milliseconds when tested by spray dilution. Samples prepared for the compositions of Examples 7, 12, 13, and 21, which do not contain the compositions according to this disclosure, have a dynamic surface tension of more than 60 mN / m over a foam surface lifetime of 20 to 50 milliseconds when tested by spray dilution.

[0165] Biological efficacy of the formulations disclosed herein: Field tests were conducted using compositions prepared according to this disclosure as broad-area herbicides. The compositions were diluted with water and optionally with other tank mix additives and applied to cultivated and uncultivated land containing many broadleaf weeds, grasses, and sedges at application rates of 150-400 g of L-glufosinate ammonium as the active ingredient per hectare, and 300-900 g of glufosinate ammonium as the active ingredient per hectare, respectively. Various samples prepared according to the present invention were tested for their effectiveness in weed control. The corresponding compositions used to prepare the samples are shown in the table (in parentheses). Samples prepared for biological efficacy determination are unrelated to samples prepared for DST determination, and therefore the sample numbers may not match; for example, sample 5 for DST determination was prepared from a composition of one example, and sample 5 for biological efficacy determination was prepared from a composition of another example. The effectiveness of comparative examples is shown in Table 20 for comparison with the effectiveness of example compositions.

[0166] The test protocols for Sample 1 and Sample 2 are shown in Table 10, and the weed control results are shown in Table 11.

[0167] [Table 10]

[0168] [Table 11]

[0169] Table 12 shows the protocol for testing samples 3-5, and Table 13 shows the weed control results.

[0170] [Table 12]

[0171] [Table 13]

[0172] The test protocol for sample 6 is shown in Table 14, and the weed control results are shown in Table 15.

[0173] [Table 14]

[0174] [Table 15]

[0175] Table 16 shows the protocol for testing samples 7-10, and Tables 17 and 18 show the weed control results.

[0176] [Table 16]

[0177] [Table 17]

[0178] [Table 18]

[0179] Table 19 shows the protocol for testing sample 11, and Table 20 shows the weed control results.

[0180] [Table 19]

[0181] [Table 20]

[0182] Analysis of the data in the table above shows that the L-glufosinate ammonium formulations prepared according to the present invention demonstrated good weed control when tested at various treatment doses. Even more surprisingly, the effectiveness of the formulations could be controlled by adjusting the dynamic surface tension, and formulations with a dynamic surface tension of less than 60 mN / m during a surface lifetime of 20–50 milliseconds were found to yield remarkably high effectiveness. When tested at a treatment dose of 157.5 g ai / ha, the compositions according to this disclosure demonstrated acceptable weed control, while the comparative compositions were found to be insufficiently effective even when tested at a higher treatment dose of 250 g ai / ha.
