Abstract
Description
Technical Field
[0001] The present invention relates to a component for use in an agrochemical active formulation, which component is for maintaining and improving the wettability, re-wettability and water retention in the soil to which it is applied. The present invention also includes a method of treating crops using such a formulation.
Background Art
[0002] Soil can be inherently hydrophobic, which is often amplified when the soil remains dry for a long time or has a high organic matter content. Soil hydrophobicity can cause the formation of water puddles and surface runoff, and in the case of turf and field crops, can directly affect plant growth due to limited infiltration and supply of water to the plant rhizosphere. The quality and physicochemical properties of the soil can directly affect the penetration and percolation of water across the soil cross-section.
[0003] To overcome this, the application of surfactants and polymers to the soil for the wetting of hydrophobic soils has become a common commercial practice. The application of anionic wetting agents has been known for decades to be advantageous for increasing the infiltration of water into hydrophobic soils. Typically, these materials have struggled to balance the application rate with crop damage and phytotoxicity prevention.
[0004] The use of non-ionic wetting agents has increased over the past decade and is now common for application to turf and amenity uses.
[0005] Although soil wettability is provided, it is still beneficial to provide a multifunctional wetting agent composition that allows for any combination with agrochemical materials for various agrochemical crop uses.
[0006] Pesticide components, especially pre-emergence herbicides, are often applied directly to the soil, but soil is inherently a hydrophobic substrate and does not readily interact with water. The hydrophobic nature of soil can limit the penetration and infiltration of irrigation-based applications. Such undesirable interactions can result in surface runoff and reduced percolation and distribution of water in the soil. Since pesticide products and their dilutions are usually applied as aqueous formulations, the need for soil treatment is highlighted. [Overview of the project] [Problems that the invention aims to solve]
[0007] The present invention aims to provide the use of a soil treatment formulation that can be used on its own or as part of an agrochemical composition, in combination with an agrochemical active substance as needed, wherein the compound can provide desired soil wetting and soil water retention. The present invention also aims to provide the use of agrochemical concentrates and diluted formulations containing the compound.
[0008] The present invention relates to enhancing water penetration into hydrophobic soils, and includes soil wetting, soil rewetting, moisture retention, and improved water percolation / filtration through the soil zone. Sufficiently wet soil is necessary for water to flow. [Means for solving the problem]
[0009] According to a first aspect of the present invention, a soil treatment formulation comprising the following is provided: (i) Sorbitan ethoxylated / propoxylated fatty acid monoesters having a fatty acid carbon chain length of 8-16 and an average total ethoxylation degree of 5-25, (ii) Ethylene oxide-propylene oxide copolymer, and (iii) A compatible surfactant selected from alkoxylated fatty alcohols, alkoxylated fatty alcohol phosphates, and / or alkoxylated glycerides.
[0010] A second aspect of the present invention provides a method for producing a soil treatment preparation according to the first aspect, comprising mixing the following: (i) Sorbitan ethoxylated / propoxylated fatty acid monoesters having a fatty acid carbon chain length of 8-16 and an average total ethoxylation degree of 5-25, (ii) Ethylene oxide-propylene oxide copolymer, and (iii) Compatibilizing surfactants selected from alkoxylated fatty alcohols, alkoxylated fatty alcohol phosphate esters, and / or alkoxylated glycerides.
[0011] According to a third aspect of the present invention, a pesticide formulation suitable for application to vegetation and / or soil is provided, comprising a diluted soil treatment formulation of the first aspect and, optionally, at least one pesticide-active substance and / or nutrient.
[0012] A fourth aspect of the present invention provides a method for wetting and / or conditioning soil, comprising applying the soil treatment formulation of the first aspect.
[0013] According to a fifth aspect of the present invention, the use of a soil treatment formulation comprising the following is provided for improving the water retention of soil and / or for soil conditioning: (i) Sorbitan ethoxylated / propoxylated fatty acid monoesters having a fatty acid carbon chain length of 8-16 and an average total ethoxylation degree of 5-25, (ii) Ethylene oxide-propylene oxide copolymer, and (iii) Compatibilizing surfactants selected from alkoxylated fatty alcohols, alkoxylated fatty alcohol phosphate esters, and / or alkoxylated glycerides.
[0014] A sixth aspect of the present invention provides a method for treating and moistening soil and / or conditioning said soil, comprising applying a diluted formulation of the first aspect to said soil.
[0015] According to a seventh aspect of the present invention, a soil treatment formulation is provided comprising a sorbitan ethoxylated / propoxylated fatty acid monoester and an ethylene oxide-propylene oxide copolymer, wherein the fatty acid carbon chain length is 8 to 16 and the total degree of ethoxylation is an average of 5 to 25. [Modes for carrying out the invention]
[0016] The soil treatment formulation of the present invention can be used to improve the physical properties of soil, particularly its wetting performance and water retention. This soil treatment formulation can be used to improve barren soil that is damaged and has insufficient wetting capacity. This soil treatment formulation can be used to make inadequate soil surfaces more usable, to maintain soil in peak condition, and to improve soil percolation. This soil treatment formulation may also be used to improve the water wetting capacity, water retention, and / or uptake capacity of the soil surface. The use of this soil treatment formulation has been found to significantly increase the water uptake / wetting rate in hydrophobic soils. Surprisingly, this combination is a stable concentrate that, compared to what has been previously achieved in the art, shows improved wetting rate (water infiltration) and improved uniformity of percolation in hydrophobic soils and plant growth media, as well as providing compatibility with various pesticide materials.
[0017] The soil treatment formulation of the present invention can be used for crops, turfgrass, and seeds, and for the production of plant growth media. This soil treatment formulation can be used, for example, for soil or sand.
[0018] Where used in this disclosure, the terms “for example,” “for instance,” “such as,” or “including” are intended to provide examples that further clarify the more general subject matter. Unless otherwise specified, these examples are provided solely to aid in understanding the uses described in this disclosure and are not intended to limit anything.
[0019] When describing the number of carbon atoms in a substituent (e.g., "C1-C6 alkyl"), this number refers to the total number of carbon atoms present in the substituent, including those in any branched group. Furthermore, when describing the number of carbon atoms in a fatty acid, for example, this refers to the total number of carbon atoms present, including those located in the carboxylic acid and those in any branched group.
[0020] Ethoxylated / propoxylated fatty acid monoesters of sorbitan have a fatty acid carbon chain length of 8 to 16, and an average total ethoxylation degree of 5 to 25.
[0021] The ethoxylated fatty acid monoester of sorbitan is preferably a compound of formula (I): [ka] In the above formula, i) Sorb represents a residue obtained by removing four hydroxyl H atoms from sorbitan. i) EO represents an ethylene oxy or propylene oxy residue, ii) n1, n2, n3, and n4 each independently represent an average value between 0 and 10, preferably between 0.5 and 5. iii) The sum n1+n2+n3+n4 has a mean of 5-25, especially 8-12. iv)R 1 , R 2 , R 3 and R 4 Each of these independently comprises H or the acyl group -C(O)-R 5 This represents, where R5 is a C7 - C 13 hydrocarbyl group, more usually a C9 - C 13 hydrocarbyl group, especially an approximately C 11 hydrocarbyl group, especially an alkyl or alkenyl group, especially a straight-chain alkyl or alkenyl group.
[0022] The sorbitan residue is obtained by removing four hydroxyl H atoms, and each of the removed H atoms is replaced by a group (AO n1 R 1 ), (AO n2 R 2 ), (AO n3 R 3 ), and (AO n4 R 4 ) to form an ethoxylated / propooxylated fatty acid monoester and should be understood as such.
[0023] Preferably, an average of 2.8 - 3.2 of the R 1 , R 2 , R 3 , and R 4 groups are H, and an average of 0.8 - 1.2 of the R 1 , R 2 , R 3 , and R 4 groups are acyl groups -C(O)-R 5 .
[0024] In the compounds of the present invention, the sorbitan residue in the core of the molecule corresponding to the residue "Sorb" in formula (I) is typically mainly a mixture of residues of 1,4-anhydrosorbitol, 1,5-anhydrosorbitol, and 3,6-anhydrosorbitol.
[0025] This mixture may typically contain some amount of 1,4,3,6-dianhydrosorbitol (iso-sorbide), but the ethoxylated products from iso-sorbide esters may not be very useful, so when iso-sorbide is present, the proportion of iso-sorbide is usually relatively low.
[0026] In contrast, 20-ethoxylated sorbitan esters are typically hydrophilic surfactants with HLB values of approximately 15 or higher. These more highly ethoxylated polysorbates are widely used in pesticide formulations as adjuvants and emulsifiers, such as Tween® 20 (sorbitan monolaurate 20-ethoxylate).
[0027] The carbon chain length of the fatty acid in the ethoxylated fatty acid monoester of sorbitan is preferably 10 to 14. More preferably, this carbon chain length is about 12.
[0028] The total ethoxylation / propoxylation degree can preferably be 5 to 25 on average. More preferably, the total ethoxylation degree can be about 10 on average.
[0029] The esters of the present invention and the esters used in the present invention are preferably monoesters. In this common type of ethoxylated sorbitan ester compound, a nominal monoester is so named because the molar ratio of sorbitol to fatty acid used to produce the sorbitan ester precursor of the ethoxylated ester is approximately 1:1, although it is common to use a slight excess of fatty acid, for example, 5-10 mol% excess.
[0030] The cyclization reaction (as described in this disclosure) yields products containing sorbitol and iso-sorbide residues, as well as those containing sorbitan residues. Furthermore, the “monoesters” (and corresponding ethoxylated derivatives) include compounds containing small proportions of unesterified polyol (sorbitol / sorbitan / iso-sorbide) residues, and a considerable proportion of mono- and dilipid acyl esters of sorbitan, but including moderate proportions based on iso-sorbide and small proportions based on sorbitol, and some tri- and higher-order esters mainly based on sorbitan. This is in contrast to nominal “trysters” of sorbitan, which mostly consist of tri- and higher-order esters. Of course, the range of individual compounds after ethoxylation is even wider.
[0031] In the initial esterification, most of the acyl residues react with primary hydroxyls in sorbitol or sorbitan (corresponding to the 1- or 6-position of sorbitol), but subsequent transesterification can be understood as causing the position of the acyl group to become largely random. Ethoxylation / propoxylation causes further transesterification, making the acyl position even more random.
[0032] In the context of the compounds of formula (I), a compound being a monoester generally means that the relative (molar) amounts of fatty acids and (usually) sorbitol used to produce the intermediate sorbitan ester (see below for further details on its synthesis) roughly correspond to the amount of monoester produced.
[0033] Therefore, preferably, for each mole of sorbitan in the compound of the present invention represented by formula (I), there are generally 0.8 to 1.2 acyl residue substituents on the sorbitan. That is, referring to formula (I), there are 0.8 to 1.2 R groups. 1 , R 2 , R 3 and R 4 The formula is -C(O)-R 5The acyl group is one of several groups, and correspondingly, 2.8 to 3.2 groups are hydrogen atoms. However, as mentioned above, esters with more than one acyl group are also commonly found in synthesized products.
[0034] The acyl group -C(O)-R in formula (I) 5 The fatty acid residues in the compound of the present invention corresponding to C8-C 14 , especially C 10 ~C 14 More specifically, approximately C 12 These are fatty acid residues. When applied to technical-grade fatty acids that are actually available, these ranges represent the average carbon chain length (and may therefore be non-integers for any individual material). Generally, the chain length of individual fatty acids in such a mixture will preferably be within 2 carbon atoms of the average value. A particularly useful source of such acyl residues is technical-grade lauric acid, which is typically mainly C8-C8. 14 It is derived from coconut oil, which is a mixture of fatty acids having the following chain lengths.
[0035] The compounds of the present invention and the compounds used in the present invention can be produced by methods generally known in the art for the corresponding known compounds—polysorbates. In particular, they can be produced from a group of commonly known sorbitan esters, usually by reaction with ethylene oxide under a basic catalyst. The basic catalyst can be sodium or potassium hydroxide or sodium or potassium methoxide. The ethoxylation reaction can typically be carried out at a temperature of 150–180°C and a pressure of 400–650 kPa (gauge).
[0036] The sorbitan esters used as starting materials for the ethoxylation reaction to produce the compounds of the present invention are generally known and can be produced by dehydrating and cyclizing sorbitol to sorbitan, and then reacting sorbitol with a suitable fatty acid to form a sorbitan ester. The suitable fatty acid has a carbon chain length of 8 to 14, preferably 10 to 14, and more preferably about 12.
[0037] The molecular weight (mass average) of the ethoxylated / propoxylated fatty acid monoester of sorbitan is preferably in the range of 400 to 2,700, more preferably 500 to 2,000, particularly 550 to 1,800, and even more preferably 550 to 1,600.
[0038] The HLB of the ethoxylated / propoxylated fatty acid monoester of sorbitan is preferably in the range of 4 to 25, more preferably 5 to 20, and particularly preferably 5 to 18.

In this embodiment, the oxyalkylene chain may be a block or random copolymer of different oxyalkylene groups.
[0047] When it is necessary to reduce the viscosity of the formulation, blocking or random copolymerization of different oxyalkylene groups of alkoxylated fatty alcohols is particularly preferred.
[0048] The number of oxyalkylene groups in each oxyalkylene chain (i.e., the value of each parameter x) is in the range of 1 to 30. Preferably, it is in the range of 2 to 25. More preferably, it is in the range of 3 to 10. Even more preferably, it is in the range of 4 to 7.

[0059] As used in this disclosure, the term “fatty alcohol residue” means the portion of a reaction scheme or subsequent formulation or chemical product that is a fatty alcohol product, regardless of whether that portion is actually obtained from a specific chemical species. A “fatty alcohol residue” refers to the portion that is produced when a fatty alcohol participates in a particular reaction (i.e., the residue is a fatty alkoxy group RO-). Thus, fatty alcohol residues are “derived” from each fatty alcohol. It has been found that this portion is essentially obtained by reaction with species other than the specific fatty alcohol, for example, by reaction with chlorides, esters, or anhydrides of unsaturated fatty alcohols.

[0088] The amount of compatibilizing surfactant contained in the preblend can be in the range of 1% to 20% by mass. More preferably, it is in the range of 4% to 15%. Even more preferably, it is in the range of 5% to 12%. Most preferably, it is in the range of 8% to 12% as a percentage of the total amount of the preblend.
[0089] The amount of ethylene oxide-propylene oxide copolymer contained in the preblend can be in the range of 30% to 70% by mass. More preferably, it is in the range of 40% to 60%. Even more preferably, it is in the range of 45% to 55%.
[0090] The concentrated formulation may be formulated to contain no other components or only small amounts of other components. Preferably, at least 90% by mass, more preferably 93% by mass, even more preferably 95% by mass, and most preferably 98% by mass of the concentrated formulation consists of polysorbate, a compatible surfactant, and ethylene oxide-propylene oxide copolymer.
[0091] In an alternative embodiment, a soil treatment formulation is provided comprising a sorbitan ethoxylated / propoxylated fatty acid monoester having a fatty acid carbon chain length of 8 to 16 and an average total ethoxylation degree of 5 to 25, and an ethylene oxide-propylene oxide copolymer. The concentrated formulation may be formulated to contain no other components or only small amounts of other components. Preferably, at least 95% by mass of the concentrated formulation consists of polysorbate and ethylene oxide-propylene oxide copolymer, and more preferably 98% by mass consists of polysorbate and ethylene oxide-propylene oxide copolymer.
[0092] In carrying out the present invention, the wet composition of the present invention can be applied by dispersing the concentrate according to the present invention in water for use as a concentrate or, more preferably, as a diluted aqueous final-use formulation.
[0093] In one embodiment, the wetting composition of the present invention can therefore be used as a spray solution for soil to promote water penetration, with or without pesticides / nutrients / soil conditioners.
[0094] Therefore, the concentrate may be diluted with water and optionally with other soil conditioners and fertilizers for application, added to a tank mixture, or formed into an internal adjuvant (containing activators or nutrients) for addition to a tank mixture.
[0095] Soil treatment formulations are designed to be diluted with water (or an aqueous liquid) to form the corresponding end-use pesticide formulation, typically a spray mixture.
[0096] Agrochemical active compounds require a formulation that allows the active compound to be taken up by plants / target organisms. When a concentrate (solid or liquid) is used as a source of agrochemical active substance and / or adjuvant, the concentrate is typically diluted to form the end-use formulation, typically a spray formulation. This dilution can be done with water at a ratio of 1 to 10,000 times, particularly 10 to 1,000 times, of the total mass of the concentrate to form a spray formulation.
[0097] The soil treatment formulation may be diluted for use to obtain a diluted composition that yields a concentration of pesticide active substance of about 0.1% to about 1% by mass. The diluted composition (for example, a spray formulation with an application rate of 10 to 500 l·ha) -1 In this case, the concentration of the pesticide active substance can be within the range of approximately 0.001% to approximately 1% by mass of the total formulation to be sprayed.
[0098] In an alternative embodiment, the soil treatment formulation can be applied using an irrigation system rather than as a spray mixture. In such a system, for example, a larger amount of water can be used to irrigate a lawn, with application rates of 50-1000 l·ha. -1 It can be within the range.
[0099] A spray formulation is an aqueous pesticide preparation containing all the components desired for application to plants or their environment. The spray formulation may be constructed by simple dilution of a soil treatment preparation containing the desired components (other than water), or by a combination of dilution of the soil treatment preparation and the addition of further individual components or mixtures of components. Typically, such end-use mixing is carried out in the tank from which the formulation is sprayed, or in a holding tank to fill the spray tank. Such mixing and mixtures are typically referred to as tank mixing and tank mixtures.
[0100] Spray formulations typically have a pH ranging from moderately acidic (e.g., around 3) to moderately alkaline (e.g., around 10), especially close to neutral (e.g., around 5-8). More concentrated formulations may have similar acidity / alkalinity, but pH is not always an appropriate measure of their pH, as they may be nearly non-aqueous.
[0101] The pesticide formulation may contain a solvent (other than water), such as monopropylene glycol, a vegetable oil, or a mineral oil, such as a spray oil. Such a solvent may be included as a solvent for the surfactant adjuvant and / or as a humectant, such as propylene glycol in particular. When used, such a solvent is typically included in an amount of 5% to 500% by mass, preferably 10% to 100% by mass, based on the mass of the surfactant adjuvant. Such combinations may also include salts, such as ammonium chloride and / or sodium benzoate, and / or urea, in particular, as a gel inhibitor.
[0102] The diluted soil treatment formulation tank mix may be sprayed onto the soil or used as a foliar spray.
[0103] This soil treatment formulation or a diluted soil treatment formulation may optionally contain other components. These other components may be selected from the following: • Binders, especially those that readily dissolve in water and provide low-viscosity solutions at high binder concentrations, such as polyvinylpyrrolidone; polyvinyl alcohol; carboxymethylcellulose; gum arabic; sugars, such as sucrose or sorbitol; starch; ethylene-vinyl acetate copolymer, sucrose, and alginate, etc. Diluents, absorbents, or carriers, e.g., carbon black; talc; diatomaceous earth; kaolin; aluminum stearate, calcium stearate, or magnesium stearate; sodium tripolyphosphate; sodium tetraborate; sodium sulfate; sodium silicate, aluminum silicate, and sodium silicate-aluminum silicate mixtures; sodium benzoate, etc. • Disintegrants, such as surfactants; materials that swell in water, such as carboxymethylcellulose, collodion, polyvinylpyrrolidone, and microcrystalline cellulose swelling agents; salts, such as sodium acetate or potassium acetate, sodium carbonate, sodium bicarbonate or sodium sesquicarbonate, ammonium sulfate, and dipotassium hydrogen phosphate; • Wetting agents, such as alcohol ethoxylates and alcohol ethoxylate / propoxylate wetting agents; • Dispersants, such as sulfonated naphthaleneformaldehyde condensates and acrylic acid copolymers, such as comb-type copolymers having capped polyethylene glycol side chains on a polyacrylic acid backbone; • Emulsifiers, such as alcohol ethoxylates, ABA block copolymers, castor oil ethoxylates, etc. • Antifoaming agents, such as polysiloxane antifoaming agents, typically in an amount of 0.005% to 10% by mass of the formulation; • Viscosity modifiers, e.g., commercially available water-soluble or miscible gums, e.g., xanthan gum, and / or cellulosic materials, e.g., carboxy-, methyl-, ethyl-, or propyl-cellulose; and / or • Preservatives and / or antimicrobial agents, such as organic acids or their esters or salts, such as ascorbic acid-based agents, such as ascorbyl palmitate; sorbic acid-based agents, such as potassium sorbate; benzoic acid-based agents, such as benzoic acid, methyl 4-hydroxybenzoate and propyl 4-hydroxybenzoate; propionic acid-based agents, such as sodium propionate; phenol-based agents, such as sodium 2-phenylphenate; 1,2-benzoisothiazolin-3-one; or formaldehyde itself or paraformaldehyde; or inorganic materials, such as sulfites and their salts, typically in an amount of 0.01% to 1% by mass of the formulation.
[0104] Furthermore, the soil wetting agent formulation or soil wetting agent of the present invention may optionally contain an active pesticide or a nutrient.
[0105] The pesticide active substance may preferably be a solid-phase pesticide active substance. In this invention, a solid pesticide active compound should be understood to mean any substance commonly used for plant treatment that has a melting point (at standard pressure) above 20°C. A solid pesticide active compound also includes insoluble active components, i.e., active components whose solubility in water is such that a considerable amount of solid content remains in the concentrate after addition.
[0106] A pesticide-active substance refers to a biocide, which in the context of this invention is a plant protection agent, more specifically, a chemical substance capable of killing various forms of organisms used in fields such as medicine, agriculture, forestry, and mosquito control. So-called plant growth regulators are also included in the group of biocides.
[0107] Biocides suitable for use in the pesticide formulations of the present invention can typically be divided into two subgroups: • Pesticides including fungicides, herbicides, insecticides, algaecides, mollusk killers, acaricides and rodenticides; and Antimicrobial agents include germicidal agents (germicides), antibiotics, antibacterial agents, antiviral agents, antifungal agents, antiprotozoal agents, and antiparasitic agents.
[0108] In particular, biocides selected from insecticides, fungicides, or herbicides can be preferably used.
[0109] The term “pesticide” will be understood to refer to any substance or mixture of substances intended to prevent, destroy, repel, or reduce harmful organisms. Pesticides can be chemical or biological preparations (e.g., viruses or bacteria) used against harmful organisms, including insects, plant pathogens, weeds, mollusks, birds, mammals, fish, nematodes (roundworms), and microorganisms that compete with humans for food, destroy property, spread disease, or cause nuisances. The following examples illustrate pesticides suitable for pesticide compositions according to the present invention.
[0110] Herbicides are pesticides used to kill unwanted plants. Selective herbicides kill specific targets, leaving desired crops relatively harmless. Some of these work by inhibiting weed growth and are often based on plant hormones. Herbicides used to clear barren land are non-selective and kill all plants they come into contact with. Herbicides are widely used in agriculture and in landscape turf management. They are applied in total vegetation control (TVC) programs for highway and railway maintenance. Smaller amounts are used for the management of forests, pasture systems, and areas reserved as wildlife habitats.
[0111] Suitable herbicides can be selected from the group including aryloxycarboxylic acids, e.g., MCPA; aryloxyphenoxypropionates, e.g., clodinafop; cyclohexanedione oximes, e.g., setoxydim; dinitroanilines, e.g., trifluralin; diphenyl ethers, e.g., oxyfluorfen; hydroxybenzonitriles, e.g., bromoxynil; sulfonylureas, e.g., nicosulphuron; triazolopyrimidines, e.g., penoxsulam; tricethions, e.g., mesotriones; or ureas, e.g., diuron.
[0112] Particularly preferred herbicides can be selected from pre-germination herbicides. As used in this disclosure, “pre-germination herbicide” means an herbicide that acts before newly germinated seedlings emerge.
[0113] Pre-germination herbicides include triazine herbicides (e.g., ametrine, atrazine, metribuzin, terbuthylazine, promethrine, propazine, simazine, trietazine, desmetryn, terbutryne, terbumeton, and cyanazine) The pre-germination herbicides for which the present invention can find specific applications can be selected from trifluralin, siduron, indaziflam, isoxaben, dithiopyr, benefin, pendimethalin, prodiamine, flufenacet, diflufenican, and aclonifen.
[0114] Fungicides are chemical agents used to control fungi. They are chemical compounds used to prevent the spread of fungi in gardens and on crops. They are also used to combat fungal infections. Fungicides can be either contact or systemic. Contact fungicides kill fungi when sprayed onto their surface. Systemic fungicides must be absorbed by the plant and the active substance redistributed before contact with the fungi.

[0126] This invention is particularly intended to be applied to formulations containing pre-emergence herbicides.
[0127] Nutrients may be present in addition to or as a substitute for pesticide active substances. In such formulations, nutrients are typically in a dried form.
[0128] Nutrients may be solid nutrients or may exist in solution form. In this invention, solid nutrients should be understood to mean substances with a melting point (at standard pressure) above 20°C. Solid nutrients may also include insoluble nutrient components, i.e., nutrient components whose solubility in water results in a significant solid content in the concentrate after addition.
[0129] Nutrients refer to chemical elements and compounds that are desirable or necessary to promote or improve plant growth. Suitable nutrients are generally described as macronutrients or micronutrients. Suitable nutrients for use in the concentrates according to the present invention are any nutritional compounds.
[0130] Micronutrients typically refer to trace metals or trace elements and are often administered in low doses. Suitable micronutrients include trace elements selected from zinc, boron, chlorine, copper, iron, molybdenum, and manganese. Micronutrients may be in soluble form or as insoluble solids, and may be in the form of salts or chelated forms.
[0131] Macronutrients typically refer to those containing nitrogen, phosphorus, and potassium, and include fertilizers such as ammonium sulfate and water conditioners. Suitable macronutrients include fertilizers, other nitrogen-containing compounds, phosphorus-containing compounds, potassium-containing compounds, calcium-containing compounds, magnesium-containing compounds, sulfur-containing compounds, and water conditioners.
[0132] Suitable fertilizers include inorganic fertilizers that provide nutrients such as nitrogen, phosphorus, potassium, or sulfur. The fertilizer may be included in a relatively low concentration in a diluted formulation, or as a more concentrated solution, and at very high levels, it may include both solid fertilizer and solution.
[0133] The nutrient content depends on the individual nutrient, and it is assumed that micronutrients are typically included at low concentrations, while macronutrients are typically included at high concentrations.
[0134] All features described herein can be combined in any combination with any of the embodiments described above. [Examples]
[0135] To make the present invention easier to understand, please refer to the following example.
[0136] It should be understood that all tests and physical properties described herein were determined at atmospheric pressure and room temperature (i.e., 25°C), unless otherwise specified in this specification or in the referenced test methods and procedures.
[0137] The following test methods were used to determine the performance of the adjuvant composition.
[0138] • Canvas Disk Test (CDT) A specified canvas disc (Cotton swatches ISO 8022) was dropped from a set distance (approximately 5 cm from the top surface of the beaker) onto the surface of 400 mL of surfactant solution (using different surfactant solutions, 0.2, 0.4, and 0.5% w / v) in a 600 mL glass beaker.
[0139] Next, the time it took for the disc to settle in the solution was recorded as the wetting time (in seconds or minutes). This method was performed to validate the capillary rise test.
[0140] Rewetting The re-wetting performance (or residual activity) of the blend was tested through a series of capillary elevation experiments. Soil plugs (pre-dried at 50°C) were placed in a 0.2% w / v aqueous solution (40 mL) of the surfactant blend, and the time it took for the solution to be absorbed by the soil plugs was recorded. After the experiment, the soil plugs were dried overnight in an oven (54°C).
[0141] After drying, the capillary elevation test was repeated up to 10 times under the same conditions as described above (referred to as rewetting 1, rewetting 2, etc. in this specification).
[0142] After the final wetting time, the soil plugs were washed by slowly pouring 400 ml of deionized water onto them (with the grass side facing up). The soil plugs were left to dry in an oven, and the next day, the capillary rise experiment was re-evaluated in the same way as the previous wetting experiment.
[0143] The following compounds were used in the test.

This method evaluates the physical compatibility of pesticides in aqueous tank mixes using a dynamic shaker system. Formulation T3, as shown in Table 1, was used for tank mix compatibility testing. The results of the compatibility test are shown in Table 4 below.
