Description

[Technical Field]

[0001] The present invention relates to a pesticide composition for application to water surfaces, a solid pesticide package thereof, and a method for producing the same. [Background technology]

[0002] Common pesticide formulations include powders, granules, wettable powders, soluble powders, flowable formulations, liquid formulations, and emulsions. Of these, spray formulations such as wettable powders, soluble powders, and emulsions are mainly used in fields and non-agricultural land. However, wettable powders and soluble powders pose health problems for workers due to dust and environmental impacts, while emulsions pose environmental pollution problems due to solvents and emulsifiers and fire hazards due to organic solvents. Furthermore, many active ingredients in pesticides are poorly soluble in water, making it difficult to formulate them into liquid formulations. For these reasons, there has been a recent trend towards increasing use of aqueous or oily suspension formulations (flowable formulations) or dry flowable formulations, which have fewer of these problems.

[0003] On the other hand, powders and granules are used as surface application agents for paddy fields, and traditionally, granules have been mainly used. Granules are generally applied at a rate of 3-4 kg per 10 ares, but in recent years, there has been a growing demand for labor-saving application of pesticides, and the development of low-volume application agents that reduce the amount of pesticide formulation applied is necessary. On the other hand, reducing the application rate of granules inevitably increases the content of the active pesticide in the granules, and the number of granules per unit area decreases. These are factors that directly affect the biological effects of the active pesticide and phytotoxicity to crops, and it is required to apply the pesticide formulation as uniformly as possible throughout the paddy field.

[0004] However, the 1kg granular formulations developed in recent years require a certain level of skill and experience to be uniformly applied to flooded paddy fields, making uniform application difficult. Furthermore, in some cases, a spraying device is required, so they are not necessarily satisfactory as a formulation intended to save labor.

[0005] Therefore, in the field of surface application agents for paddy fields, there has been a surge in the development of aqueous suspension formulations aimed at reducing labor and improving efficiency during application. Unlike aqueous suspension formulations used in fields and non-agricultural land, these formulations are dropped or poured directly into the paddy field from the container without dilution, thus eliminating the need for special spraying equipment. Furthermore, the application volume of these formulations is small, approximately 200 milliliters to 1 liter per 10 ares, making them lightweight and easy to handle. Depending on the field area, application can be done by pouring from the levees (so-called perimeter application) or by simply irrigating from the water inlet when water is introduced (so-called water inlet application). Consequently, these formulations allow for extremely labor-saving application and have rapidly expanded their market share since their release. However, aqueous suspension formulations have the drawback of being difficult to apply to pesticides with easily hydrolyzable active ingredients, as they are formulations in which the active ingredient of the pesticide is dispersed or emulsified in water.

[0006] In recent years, as a way to reduce the labor involved in pesticide application and to consider environmental factors, there has been a growing trend towards the widespread use of paddy field pesticide formulations (pack formulations or jumbo formulations) that are packaged in water-soluble paper such as water-soluble film, and are solid formulations such as tablets, bean-shaped formulations, and granules. While these formulations have the advantage of easily treating paddy fields with pesticides, they do not provide the same uniform treatment as conventional granular or powder formulations. Furthermore, when these solid formulations are thrown into water, they settle on the soil surface. Here, the settled material disperses the pesticide active ingredients in the paddy field water, either by foaming or not, so undissolved active particles settle around the point of application. In addition, the dissolved pesticide active ingredients form a highly concentrated solution near the soil surface at the application point, making them easily adsorbed by the soil. Therefore, even if the water solubility of the active pesticide in these solid formulations, which are packaged in water-soluble paper such as water-soluble film for use in paddy fields, is quite high, the active pesticide is adsorbed at a high concentration in the soil near the point of application. Depending on field conditions, weather conditions, etc., this can easily lead to phytotoxicity, uneven efficacy, and adverse effects on subsequent crops due to the uneven distribution of the active pesticide.

[0007] In the past, many effervescent tablets were developed as a type of granular formulation, but due to challenges in terms of manufacturability and storage stability, the use of non-effervescent granular formulations has become mainstream. For example, [1] a water-floating solid pesticide preparation containing (1) an active pesticide ingredient, (2) a water-floating granular core containing one or more selected from calcined vermiculite, foamed perlite, foamed shirasu, and cork, and (3) one or more water-expanding agents selected from acetylene alcohol, acetylenediol, and surfactants to which alkylene oxide has been added, packaged in a film or sheet made of polyvinyl alcohol, its derivatives, or polyvinyl alcohol and its derivatives, in which the active ingredient is dispersed or dissolved in water, for use in dumping into rice paddies (Patent No. 2815535; Patent Document 1), [2] a pesticide granule or tablet in which (1) an active pesticide ingredient, (2) a powder base with a specific gravity of 1 or less, and (3) a surfactant with a high ability to reduce interfacial tension are uniformly dispersed (Japanese Patent Publication No. 7-233002; Patent Document 2), [ [3] A water surface application pesticide formulation characterized by having good floating and moving properties, comprising (1) a granular core having an apparent specific gravity of less than 1 and a particle size in the range of about 300 μm to about 1,400 μm, on which (2) an active pesticide and (3) a substance capable of changing the air-water surface tension are supported and coated with (4) an oily substance (Japanese Patent Publication No. 9-183701; Patent Document 3), [4] A water surface application pesticide composition containing (1) one or more active pesticide ingredients, (2) one or more surfactants selected from the group consisting of α-olefin sulfonates, α-sulfo fatty acid salts and oleyl methyl tauride salts and (3) a molded granular core having an apparent specific gravity of less than 1 and containing a hollow mineral carrier, plant carrier, synthetic resin foam, or one or more of these to impart the property of floating on water (Japanese Patent No. 3535429; Patent Document 4), [5] C4~C 10A water-floating solid pesticide formulation containing one or more water-floating agents consisting of C2-C4 alkylene oxide adducts of alkyl alcohols and their derivatives, and an active pesticide ingredient (Japanese Patent Publication No. 2000-351701; Patent Document 5), and a solid pesticide formulation for paddy fields, wherein the water-floating agent is 2-phenoxyethanol, 1-phenoxyethanol, etc., having a specific gravity of 1.15 or less and a water solubility in the range of 0.01 to 10%. A solid formulation of pesticides for paddy fields (Patent No. 4280017; Patent Document 6) is characterized by being at least one organic solvent selected from noxy-2-propanol, 3-methoxy-3-methylbutyl acetate, and 3,5,5-trimethyl-1-hexanol, and being at least one surfactant selected from alkylallyl sulfonate inorganic phosphate, isobutylene-maleic acid copolymer, polycarboxylate, and polyacrylate, and is known as a technology for improving the spreadability of floating granular formulations on the water surface. [Prior art documents] [Patent Documents]

[0008] [Patent Document 1] Patent No. 2815535 [Patent Document 2] Japanese Patent Publication No. 7-233002 [Patent Document 3] Japanese Patent Publication No. 9-183701 [Patent Document 4] Patent No. 3535429 [Patent Document 5] Japanese Patent Publication No. 2000-351701 [Patent Document 6] Patent No. 4280017 [Overview of the project] [Problems that the invention aims to solve]

[0009] However, these existing methods have not always been able to achieve sufficient surface diffusion in practical situations. In other words, in practical situations, algae, rice husks, and other floating matter often cover the surface of paddy fields. In such cases, even if the existing surface application agents are applied, the floating matter inhibits the diffusion of the active pesticide components, making it impossible to uniformly diffuse the active pesticide components. Furthermore, even in paddy fields that appear to be free of floating matter, there may actually be floating matter that cannot be seen by the naked eye from the ridge. In such cases, even if existing surface application agents are applied, sufficient diffusion of the active pesticide components cannot be expected. In particular, during the period when so-called mid-season agents and blast agents are applied, the diffusion of active pesticide components is inhibited not only by the increase in floating matter on the water surface but also by the growth of rice and weeds. Therefore, to achieve practical effects, it is necessary to further strengthen the diffusion performance of the pesticide.

[0010] The problem of the present invention is to design an agricultural chemical formulation that will float and spread well on the water surface even when suspended matter that inhibits the floating and spreading of the active ingredient of the agricultural chemical is present in paddy fields, and even when rice and weeds are growing. However, until now, no technology has been known that is sufficient to solve this problem and several other problems simultaneously. In other words, there was a demand for an agricultural chemical formulation that: 1) does not require special equipment for spraying, 2) is labor-saving, 3) is safe for sprayers and the environment, 4) does not use standardized containers such as plastic containers, making container disposal easy, 5) does not pose a risk of insufficient efficacy due to segregation of the active ingredient or phytotoxicity due to uneven distribution, 6) has excellent floating and spreading properties on the water surface even when there are some obstacles and when rice and weeds are growing, and 7) is stable over time, as well as a method for disposing of it. [Means for solving the problem]

[0011] The inventors of the present invention conducted diligent studies aimed at developing a pesticide formulation and a method of processing the same that satisfies the above conditions. As a result, they found that a novel pesticide composition comprising a glycol ether-based solvent as a liquid spreading agent component, a specific granular core with an apparent specific gravity of less than 1, and a coating layer containing one or more solid surfactants is present. They also found that by filling the pesticide composition into a suitable container equipped with a spout and directly distributing it into a paddy field, or by dispersing the pesticide composition by breaking open a bag with water or by dividing it into small packets in a water-soluble film and throwing these into the paddy field, the settling of the active ingredient of the pesticide composition is suppressed at the point of application, allowing it to float and spread well on the water surface of the paddy field and distribute the pesticide active ingredient well throughout the paddy field water. Thus, the present invention was completed.

[0013] The water surface application pesticide composition of the present invention is compared with the prior art described above, as follows.

[0014] In other words, when comparing the water surface application pesticide composition of the present invention with the water surface floating solid pesticide formulation of Patent Document 1, both are common in terms of the active pesticide ingredient and the water surface floating granular core, but the water surface application pesticide composition of the present invention contains a glycol ether-based solvent and a solid surfactant in the coating layer, whereas the water surface floating solid pesticide formulation of Patent Document 1 contains one or more water surface spreading agents selected from acetylene alcohol, acetylenediol, and surfactants to which alkylene oxide has been added.

[0015] When comparing the surface-applied pesticide composition of the present invention with the pesticide granules or tablets of Patent Document 2, both share the same pesticide active ingredient and surface-floating granular nuclei (in Patent Document 2, this is described as a powder base with a specific gravity of 1 or less). However, the surface-applied pesticide composition of the present invention contains a glycol ether-based solvent and a solid surfactant in the coating layer, whereas the pesticide granules or tablets of Patent Document 2 have a uniformly dispersed surfactant with high interfacial tension-reducing ability.

[0016] The water surface application pesticide composition of the present invention and the water surface application pesticide formulation of Patent Document 3 share common features, including the active pesticide component, water surface floating granular nuclei (in Patent Document 3, these are defined as having an apparent specific gravity of less than 1 and a particle size in the range of approximately 300 μm to approximately 1,400 μm, while in the present invention, typically 90% or more of the granular nuclei fall in the 0,500 mm to 4,760 mm range), and the fact that the water surface application pesticide formulation is made by supporting and coating a substance capable of changing the air-water interfacial tension with an oily substance. However, the water surface application pesticide composition of the present invention contains a glycol ether-based solvent, while the water surface application pesticide formulation of Patent Document 3 does not contain a glycol ether-based solvent.

[0017] The water surface application pesticide composition of the present invention, when compared with the water surface application pesticide composition of Patent Document 4, both contain an active pesticide ingredient, a water surface floating granular nucleus, and a solid surfactant (in Patent Document 4, this is one or more surfactants selected from the group consisting of α-olefin sulfonate, α-sulfo fatty acid salt, and oleyl methyl tauride salt). However, the water surface application pesticide composition of the present invention contains a glycol ether-based solvent, while the water surface application pesticide formulation of Patent Document 4 does not contain a glycol ether-based solvent, and thus the two differ.

[0018] The water surface application pesticide composition of the present invention, when compared with the water surface application pesticide composition of Patent Document 5, differs in that both contain the same pesticide active ingredient, water surface floating granules, and glycol ether solvent (however, Patent Document 5 uses C4-C 10While both contain alkyl alcohol C2-C4 alkylene oxide adducts and their derivatives, the water surface application pesticide composition of the present invention contains a solid surfactant in its coating layer, whereas the water surface application pesticide formulation of Patent Document 5 contains the surfactant only inside the granular nucleus and not in its coating layer.

[0019] When comparing the surface-applied pesticide composition of the present invention with the surface-applied pesticide composition of Patent Document 6, both contain a polycarboxylate as an active pesticide ingredient, a surface-floating granular nucleus, and a surfactant. However, the surface-applied pesticide composition of the present invention is characterized by coating the granular nucleus with a solid surfactant, that is, by containing a solid surfactant in the coating layer. In contrast, referring to the description of the production of the paddy field pesticide solid formulation and Examples 1 to 12 in paragraph

[0034] of the specification, the formulations in each example of the surface-applied pesticide formulation of Patent Document 6 are characterized by being obtained by performing a granulation process using water and then subjecting the obtained granules to a drying process. Therefore, the surface-applied pesticide composition of the present invention has a coating layer containing a solid surfactant, while the surface-applied pesticide formulation of Patent Document 6 is obtained by kneading and granulating, and thus the two differ. In the water surface application pesticide composition of the present invention, the active ingredient can be rapidly dispersed together with the surfactant from the coating layer of the outer part, which is a structural feature, whereas in the water surface application pesticide composition of Patent Document 6, the surfactant is gradually eluted (or released) from the granules, so the active ingredient diffuses gradually. Furthermore, since the water surface application pesticide formulation of Patent Document 6 is made by kneading granulation, the particle size becomes large, and in its manufacturing process, it goes through a water mixing process, a granulation process, and a drying process, which is disadvantageous in terms of manufacturing handling and manufacturing efficiency compared to the water surface application pesticide composition of the present invention, which can directly treat the granule core with a solid surfactant and form a coating layer without going through a water mixing process, a granulation process, and a drying process. [Effects of the Invention]

[0020] According to the present invention, when the surface-applied pesticide composition is applied to a flooded paddy field, the spreading force of the glycol ether solvent and the solid surfactant contained in the coating layer suppresses the settling of the active ingredient at the point of application, and the surface-applied pesticide composition self-diffuses in various directions on the water surface, allowing the pesticide active ingredient to be quickly and uniformly dispersed and dissolved in the paddy field water. Furthermore, the surface-applied pesticide composition of the present invention has a desirable feature in practical applications: because the rate of release of the pesticide active ingredient into the water is fast, even if granular nuclei remain on the water surface and are blown away by the wind, the pesticide active ingredient has already been released from the granular nuclei before they are blown away, so it does not significantly affect the manifestation of its effect. [Brief explanation of the drawing]

[0029] Furthermore, "liquid pesticide active ingredients" can also be used as the "liquid pesticide active ingredients" of the present invention. "Liquid pesticide active ingredients" refers to a liquid substance obtained by heating and dissolving a pesticide active ingredient with a low melting point (e.g., 30°C to 70°C) or by dissolving the pesticide active ingredient in a predetermined solvent. Examples include etofenprox, cyhalofop-butyl, dimethametrin, and benfreesate.

[0030] Furthermore, any liquid pesticide active ingredient that remains liquid even after adding a new pesticide active ingredient to the above-mentioned liquid pesticide active ingredient is included in the liquid pesticide active ingredient of the present invention.

[0031] There are no particular restrictions on the solvent used to prepare the liquid active ingredient of a pesticide, as long as it is generally contained in pesticide formulations and can dissolve the desired active ingredient.

[0042] The aqueous-applied pesticide composition of the present invention contains a pesticide active ingredient, a specific granule core with an apparent specific gravity of less than 1, and a liquid spreading agent, and is characterized by including a coating layer containing a solid surfactant on the surface of the granule core. Note that the coating layer containing a solid surfactant on the surface of the granule core may be formed directly or through other layers.

[0045] The solid surfactant of the present invention is generally any surfactant that is solid at room temperature (20°C). However, it is not limited to this, and even liquid surfactants, or solidified surfactants obtained by mixing such liquid surfactants with a solid carrier such as amorphous silicon dioxide, can be used in the present invention.

[0046] The solid surfactant used in the present invention is not particularly limited as long as it is a surfactant commonly used in agricultural chemical formulations. However, polycarboxylates and alkylbenzene sulfonates are preferred because they not only have excellent spreading properties but also effectively suppress the settling of the active ingredient at the point of application, and polycarboxylates are particularly preferred.

[0047] There are no particular limitations on the polycarboxylate salts used in the present invention, but examples include acrylic acid polymers, methacrylic acid polymers, copolymers of acrylic acid and methacrylic acid, copolymers of acrylic acid and methyl methacrylate, copolymers of acrylic acid and vinyl acetate, copolymers of maleic acid and acrylic acid, copolymers of maleic acid and styrene, copolymers of isobutylene and maleic acid, and surfactants selected from the group consisting of alkali metal salts, ammonium salts, and organic salts of these polymers.

[0050] As the alkylbenzene sulfonate, dodecylbenzene sulfonate is preferred.

[0051] The granular core used in the present invention is not particularly limited as long as it is a granular material that functions as a buoyancy material and has the property of floating on water, but it means a granular core containing one or more types of hollow mineral carriers, plant carriers and / or synthetic resin foams (the apparent specific gravity of the granular core is less than 1). Examples include hollow mineral carriers such as calcined vermiculite, calcined vermiculite, expanded perlite, and expanded shirasu; plant carriers such as cork; and granular materials such as expanded polystyrene and other synthetic resin foams, as well as granular materials molded to contain one or more of these and to be given the property of floating on water. Preferably, calcined vermiculite, expanded perlite, expanded shirasu, or cork are used, and more preferably calcined vermiculite, expanded perlite, or cork. The blending ratio in the surface application pesticide composition of the present invention is preferably 1 to 50% by weight of the total amount of the composition, and more preferably 10 to 40% by weight.

[0052] The water surface application pesticide composition of the present invention can be manufactured, for example, by supporting an active pesticide ingredient on granular nuclei having an apparent specific gravity of less than 1 and coating them with a solid surfactant, or by coating the surface of granular nuclei having an apparent specific gravity of less than 1 with an active pesticide ingredient and a solid surfactant.

[0053] When loading pesticide active ingredients, etc., onto granular nuclei with an apparent specific gravity of less than 1, the amount of pesticide active ingredients, etc., onto the granular nuclei is sufficient as long as it is within the range of the amount that the surface-applied pesticide composition floats on the water surface. The amount varies depending on the type and grade of granular nuclei, the type of pesticide active ingredients, and the types and amounts of other auxiliary agents, etc., and can be appropriately selected and blended, but in order to impart buoyancy to the surface-applied pesticide composition of the present invention, the blending ratio in the surface-applied pesticide composition of the present invention is usually 10 to 90% by weight, preferably 20 to 70% by weight.

[0054] In step 1) of the method for producing the surface application pesticide composition of the present invention described above, in the "step of treating a glycol ether solvent with an oily substance and / or a liquid pesticide active ingredient as appropriate," "as appropriate" means that the oily substance and / or liquid pesticide active ingredient may or may not be treated.

[0055] As a treatment in step 1) of the method for producing the surface-applied pesticide composition of the present invention, for example, a glycol ether solvent and an appropriate oily substance and / or an appropriate liquid pesticide active ingredient may be impregnated simultaneously or separately into granular nuclei having an apparent specific gravity of less than 1.

[0056] As a treatment in step 2) of the method for producing the surface-applied pesticide composition of the present invention, for example, the granular nuclei obtained in step 1) may be treated simultaneously or separately with one or more pesticide active ingredients [however, if liquid pesticide active ingredients were treated in step 1), the number of pesticide active ingredients in this step will be zero or one or more] and one or more solid surfactants (however, the granular nuclei are coated with at least one solid surfactant). Here, the granular nuclei may be directly coated with at least one solid surfactant, or coated via another layer.

[0057] From the standpoint of reducing the number of steps, it is preferable that the method for producing the pesticide composition of the present invention does not include a drying step for the granular nuclei obtained in steps 1) and 2) above for the production of the pesticide composition.

[0058] In this invention, it is preferable that the pesticide active ingredient be coated on the granular nucleus, and more preferably that it be contained in the same coating layer as the solid surfactant, in order to increase the rate of release of the pesticide active ingredient into water.

[0059] When coating the surface of granular nuclei with an apparent specific gravity of less than 1 with an active pesticide ingredient and a solid surfactant, the water surface application pesticide composition of the present invention can be manufactured by the following coating method.

[0060] In other words, (1) a method of coating granular nuclei, which normally have an apparent specific gravity of less than 1, with a glycol ether-based solvent and an oily substance, and then coating the resulting granular nuclei with a solid active ingredient of pesticide and one or more solid surfactants, and further with other appropriate auxiliary agents;

[0061] (2) A method of moistening the surface of granular nuclei having an apparent specific gravity of less than 1 with a liquid active pesticide ingredient, a glycol ether solvent, and an oily substance, and then coating the resulting granular nuclei with one or more solid surfactants, and further with other auxiliary agents and the remaining solid active pesticide ingredient as appropriate; and

[0062] (3) A method of coating granular nuclei having an apparent specific gravity of less than 1 with one or more solid surfactants by moistening the surface of the granular nuclei with a liquid active ingredient of a pesticide, a glycol ether solvent, and an oily substance; That is the case.

[0063] Furthermore, when impregnating granular nuclei having an apparent specific gravity of less than 1 with a liquid composition containing an active ingredient in pesticides, a glycol ether-based solvent, and a liquid spreading agent, the granular nuclei of the present invention can be manufactured by the following impregnation method.

[0064] In other words, this method involves impregnating granular nuclei, which typically have an apparent specific gravity of less than 1, with a liquid composition containing an active pesticide ingredient, a glycol ether-based solvent, and one or more liquid surfactants, as well as other auxiliary agents as appropriate.

[0065] The oily substance used in the present invention can be any substance that does not adversely affect the active ingredient of the pesticide, such as causing particle growth or decomposition, and that can uniformly coat the surface of granular nuclei with the active ingredient of the pesticide, which has an apparent specific gravity of less than 1. Preferably, it is a solvent with a high boiling point, low toxicity, a high flash point, low viscosity, a specific gravity less than 1, and low dissolving power for the active ingredient of the pesticide. Examples include hydrocarbon solvents (mineral oils) such as low-viscosity liquid paraffin, chlorinated paraffin, isoparaffin, machine oil, polybutene, paraffinic, naphthenic, and aromatic high-boiling point solvents; and vegetable oils such as coconut oil, soybean oil, and rapeseed oil. Examples include animal oils such as whale oil and sardine oil; various esters of monomers or dicarboxylic acids such as silicone oil, oleic acid, coconut oil fatty acid, maleic acid, fumaric acid, phthalic acid, and adipic acid; plasticizers such as various esters of phosphoric acid such as tributyl phosphate and trichloroethyl phosphate; glycols such as ethylene glycol, diethylene glycol, and butanediol, and their various esters and ethers; lactones such as ε-caprolactone and γ-butyrolactone; N-methylpyrrolidone; and various liquid surfactants. Preferably, the solvent is a hydrocarbon solvent (mineral oil), and more preferably, liquid paraffin.

[0066] The amount of oily substance used in the present invention varies depending on the type of active pesticide ingredient and other auxiliary agents, and can be appropriately selected and blended. However, in order to impart good surface-floating and spreading properties to the surface-applied pesticide composition of the present invention, the blending ratio in the surface-applied pesticide composition is usually 1 to 60%, preferably 5 to 40%.

[0067] The pesticide composition for application to the water surface is not particularly limited as long as it is in a formulation commonly used for application to the water surface, but granular formulations are preferred.

[0068] The binder used in the present invention can be used to form a mixture of granular nuclei with an apparent specific gravity of less than 1, and other auxiliary agents as appropriate, as well as pesticide active ingredients, glycol ether solvents, solid surfactants, and other water surface expanding agents into granules. Examples include dextrin, polyvinyl alcohol, polyvinylpyrrolidone, carboxymethylcellulose salts, methylcellulose, gum arabic, polyethylene glycol and its derivatives, as well as tab powder and bentonite. Furthermore, polysorbates of the lignin sulfonate, carboxylic acid, and sulfonic acid types can also be used as dispersants. In addition, bentonite and lignin sulfonate are particularly useful because they are relatively inexpensive and can be used as bulking agents.

[0069] In the present invention, bentonite and sodium salts of carboxymethylcellulose are particularly advantageous as binders because they have strong binding power, can control the disintegration time of the granules in water, and, moreover, have swelling properties themselves, allowing the granules to completely disintegrate once disintegration begins.

[0070] The amount of binder used in the present invention varies depending on the type of binder, the type, composition and manufacturing method of the granular nuclei with an apparent specific gravity of less than 1; the formulation, manufacturing method and shape of the pesticide granules; the type and physical properties of the pesticide active ingredient; and the type and amount of other auxiliary agents, but can be appropriately selected and determined. For example, in the case of bentonite, the blending ratio is usually 3 to 70%, preferably 5 to 30%, in the surface application pesticide composition of the present invention, while in the case of other binders, the blending ratio is 0.1 to 30%, preferably about 0.5 to 20%.

[0071] The surface application pesticide composition of the present invention may contain other auxiliary agents for various purposes. Other auxiliary agents that can be added include, for example, surfactants, oil-absorbing carriers, defoamers, fungicides, solvents, stabilizers, colorants, fillers, preservatives, and pH adjusters. Surfactants are preferred.

[0072] The surfactant used in the present invention is not particularly limited as long as it is one that is commonly used in pesticides.

In addition, one or more pH adjusting agents may be used in combination.

[0087] Next, the water surface application pesticide composition and the method for producing the same of the present invention will be described. Note that the following description is illustrative and does not limit the present invention.

[0088] When using liquid pesticide active ingredients, impregnate granular nuclei or oil-absorbing carriers with an apparent specific gravity of less than 1 with the liquid pesticide active ingredient, glycol ether solvent, and an appropriate oily substance, and then form granules in the same manner as for solid pesticide active ingredients. Subsequently, in the same manner as for solid pesticide components, the granules are manufactured by coating them with a solid surfactant.

[0089] When the water surface application pesticide composition of the present invention is in granular form, if the particle size of the granules is such that a large portion is larger than 0.5 mm, they will not sink easily in water. Conversely, if the particle size is smaller than 5 mm, they will not be easily blown away by the wind and will pass more easily between growing rice plants, thus reducing the likelihood of segregation of the active ingredient. Therefore, it is preferable that 90% or more of the particle size of the granules falls within the range of 0.500 mm to 4.760 mm.

[0090] The water surface application pesticide composition of the present invention obtained in this manner can be directly poured into paddy fields from a box, bottle, bag, etc., equipped with a suitable pouring spout, or it can be thrown directly into paddy fields from the levees or other areas as a pesticide package in water-soluble film or sheet. Since the water surface application pesticide composition of the present invention is designed to release the active pesticide component while spreading on the water surface, sufficient biological effects can be obtained by appropriately applying it into paddy fields from the levees or other areas, without having to enter the paddy field and uniformly scatter it, as is the case with general granular pesticides. The water-soluble film or sheet used in the present invention is a film or sheet having properties that dissolve or disperse in water. Examples of its constituent materials include those made of polyvinyl alcohol or its derivatives, those made of polyvinyl alcohol-based fibers (e.g., nonwoven fabric), those made of pullulan film, those made of sodium salt of carboxymethylcellulose and cellulose, and those made of polyethylene oxide and its derivatives. In particular, a film made of polyvinyl alcohol or its derivatives (hereinafter abbreviated as PVA film) readily disperses or dissolves in water itself and has the property of spreading the surface application pesticide composition of the present invention on the water surface.

[0091] The PVA film used in this invention is, for example, a film made by forming polyvinyl alcohol with a degree of polymerization of 1000 to 2000 and a degree of saponification of 85 to 95% together with a small amount of plasticizer, stabilizer, etc., and also includes films that contain a small amount of copolymer such as carboxylic acid in the polymer. The thickness of the PVA film is usually 25 to 70 μm, preferably 30 to 50 μm, after considering the film strength and dissolution time. Furthermore, it is advantageous that the edges of the PVA film can be heat-sealed.

[0092] When packaging in the above-mentioned PVA film, the weight of one package is usually 10 to 200 g, preferably 20 to 60 g, taking into consideration ease of distribution. The number of packages is usually 2 to 40 per 10 ares to achieve sufficient biological effect, preferably 4 to 20.

[0097] In this specification, the "spreadability index" is a numerical representation of the spreadability of a water surface application pesticide composition on the water surface, ranging from 0 to 15 points (out of a maximum of 15 points). A higher score indicates better water surface spreadability, preferably 7 points or higher, more preferably 9 points or higher, and even more preferably 11 points or higher. The test method for water surface spreadability is as follows.

[0098] Fill a 4m long and 14cm wide gutter with 25L of tap water and, simulating obstacles (floating objects) on the water surface, add 2g of rice husk powder to the water surface until evenly distributed. After standing, add 300mg of a water surface pesticide composition to a point 10cm from one end of the gutter. Visually inspect the time it takes for each water surface pesticide composition to reach 1.5m from the point of application, the maximum distance it reaches from the point of application, and the state of spread 5 minutes after application. Determine the results according to the evaluation criteria listed in Table 1 below, and calculate the spread index for each item by summing the spread indices for each item.

[0099] [Table 1]

[0100] In this specification, "suspension" refers to the amount of a pesticide composition applied to the water surface that settles in the water. It is a simple method for measuring the amount of sedimentation at the point of application when the pesticide is applied to a paddy field. A smaller "suspension" indicates less sedimentation, which reduces the likelihood of phytotoxicity due to segregation of the main ingredient near the application point. Preferably, it is 1.0 ml or less, and more preferably 0.7 ml or less. The test method for suspension is as follows.

[0101] Place 500 ml of 3-degree hard water at 20°C into the suspension tester shown in Figure 1. Add 3 g of granules and gently stir with a glass rod 10 times (rotation speed 1 time / second). Allow to stand for 10 minutes, read the volume of the settled sample in ml, and determine the suspension. [Examples]
