Description

TECHNICAL FIELD [0001] The present invention relates to a granular agricultural chemical composition,

More particularly, the present invention relates to a pesticidal composition for floating on a water surface, and more particularly, to a pesticidal composition for pesticidal active ingredients which can be uniformly dispersed by partially spraying a small amount of water on a water surface, The present invention relates to a water-borne large-scale granular pesticide composition and a method for producing the same.

Conventionally, pesticidal compositions used in non-ionic liquids generally include granules, powders, emulsions, wettable powders, and flowable compositions. In these pesticidal compositions, the granules and the powders are usually sprayed directly without diluting 1 to 4 kg per 10a of water. However, in recent years, it has been strongly required to reduce the labor of spraying pesticides. To cope with this, There is a demand for a pesticide composition capable of spraying a pesticide composition which can be sprayed only by throwing it from a row without reducing the amount of the pesticide composition or increasing the content of the pesticide composition.

For example, Patent Document 1 discloses a pesticidal composition containing a pesticidal active ingredient and having a particle size distribution of not less than 80% of not less than 3 mm in particle diameter and not more than 80% , And has a property of floating on the water surface, and disintegrates at the water surface within 30 minutes. The pesticidal composition has a high self-diffusing property. Since the active ingredient of the pesticide spreads uniformly over the whole munon by spraying a small amount of the pesticidal composition in an amount of about 250 to 500 g per 10 g of mucilage, It can be said that it is an ideal pesticide composition corresponding to a spreading force.

The granular pesticide composition disclosed in Patent Document 1 is designed to be self-dispersing by collapsing while floating on the water surface when treated with non-nanoparticles. As a premise for exhibiting such performance, the composition is required to be suspended in water. As a method for imparting buoyancy to a granular pesticide composition, there has been proposed a method of imparting buoyancy to a granular pesticide composition, including pearlite composed of perlite and obsidian, foamed silis composed of silis, fillite sintered in aluminosilicate, micro ballon foamed with sodium silicate or borax ), Pneumatic microballoons made of phenol resin, eco spares made of epoxy resin, polyurethane foam made of polyurethane, microspheres made of polyacrylonitrile , Fly ash produced as a batch at the time of thermal power generation, a method of containing a floating carrier having one or more independent air chambers, a method of containing water-repellent substances such as stearic acid and its salts and hydrophobic white carbon Is disclosed.

Further, a hollow microballoons having a wall film of a thermoplastic polymer (hereinafter referred to as "plastic microballoons" in the present specification) are potent floating carriers capable of imparting sufficient buoyancy to the granular pesticide composition in a small amount, Patent Document 2 discloses that when the granular pesticide composition is produced by extrusion granulation, the granulation weight per unit time, that is, the effect of improving the granulation property is also exhibited. Therefore, when the granular pesticide composition described in Patent Document 1 is to be prepared by the extrusion granulation method, the plastic microballoons are floating carriers which are actively to be employed.

However, the plastic microballoons are extremely light powders having a true specific gravity of about 0.02 to 0.04. On the other hand, the true specific gravity of the solid carrier generally used in solid pesticide compositions such as clay, calcium carbonate, diatomaceous earth, white carbon and the like is about 2 to 3, and the true specific gravity of the agrochemical active ingredient and the surfactant is not usually lower than 1. In order to produce the granular pesticide composition described in Patent Document 1 by the extrusion granulation method, a step of obtaining a homogeneous raw material mixture by mixing a pesticidal active ingredient, a surfactant, and a raw material including a plastic microballoon and a solid carrier before a granulation process is required , The plastic microballoons are difficult to mix with other raw materials in accordance with the difference in true specific gravity.

If the mixing of the raw materials is inadequate, the granular pesticide composition in which the density of the plastic microballoons of the raw material mixture is low and the plastic microballoons are small, is poor in buoyancy and precipitates when added to water, It becomes a defective particle which can not exert its own self-dispersibility. Since the poor particles are difficult to distinguish from the normal particles floating in the water until they are put into water, the lot after which the defective particles are found in the specimen sampled by the quality inspection after the assembling step The entire amount is forced to be discarded and the economic loss becomes enormous. Therefore, in order to obtain a homogeneous raw material mixture containing plastic microballoons, it was necessary to carefully mix with sufficient time.

Further, in the granular pesticide composition of the present invention, a surfactant may be blended to disintegrate the particles at the water surface and diffuse the agricultural chemical active ingredient into water. As the surfactant that can be used, those generally used in an agricultural chemical composition can be used.

Examples of specific surfactants include polyethylene glycol higher fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene alkyl aryl ethers, polyoxyethylene aryl phenyl ethers, sorbitan monoalkylates, acetylenic alcohols and acetylenic diols and alkylene oxides thereof Non-ionic surfactants such as adducts; Alkyl sulfonic acid salts, alkyl sulfonic acid salts, alkyl sulfonic acid salts, lignin sulfonic acid salts, naphthalene sulfonic acid salts and condensates thereof, alkyl sulfuric acid ester salts, alkyl phosphoric acid ester salts, alkylaryl sulfuric acid ester salts, alkylaryl phosphoric acid ester salts and polyoxyethylene alkyl sulfuric acid ester salts , Polyoxyethylene alkyl aryl ether sulfuric acid ester salt, polyoxyethylene aryl phenyl ether sulfuric acid ester salt, polycarboxylic acid type polymer active agent, and other anionic surfactants; Cationic surfactants such as tetraalkylammonium salts, alkylamines, and alkylpyridinium salts; Amphoteric surfactants such as alkyl betaines, alkyl amine oxides, alkyl imidarium betaines, and amino acids; Furthermore, a silicone surfactant and a fluorinated surfactant can be given.

The granular pesticide composition of the present invention is required to float on the surface of water. Examples of the method for imparting a water surface oil repellency to the granular pesticide composition include pearlite composed of perlite and obsidian, foamed silas with silis, pilite sintered with aluminosilicate, microballoons foamed with sodium silicate or borax, Phenol microballoons made of phenol resin, eco spares made of epoxy resin, polyurethane foam composed of polyurethane resin, and microcapsules made of polyacrylonitrile resin A method of including a hollow body having one or more independent chambers, such as a balloon, a fly ash produced as a raw material for thermal power generation, and a method of containing a water repellent material such as stearic acid and its salt and hydrophobic white carbon , A hollow body having one electron chamber or a plurality of hollow chambers As the hollow body, the plastic microballoons containing the thermoplastic polymer as a wall material can ensure the water surface lubricity of the granular pesticide composition in a small amount of less than 5 mass% based on the total amount of the granular composition, And also exhibits a side effect of improving the assembling property when extruding and assembling water.

Examples of the thermoplastic polymer as the wall material of the plastic microballoons include vinyl-based polymers such as hard or soft polyvinyl chloride, polyvinylidene chloride or polyvinyl alcohol; Polystyrene, high-density, medium-density or low-density polyethylene, and ethylene / vinyl acetate copolymer; Unmodified polypropylene; Polymer or copolymer polyacetal-based polymer; Acrylic polymers such as polymethyl methacrylate and methacryl / styrene copolymer; Cellulose acetate; Polycarbonate; Polyester-based polymers such as polyethylene terephthalate; Polyamide-based polymers such as nylon 6 and nylon 66; Thermoplastic polyurethane; Tetrafluoroethylene / hexafluoropropylene copolymer, tetrafluoroethylene / perfluoroalkoxyethylene copolymer, tetrafluoroethylene / ethylene copolymer, vinylidene fluoride and the like may be used. A fluorine-based polymer, and the like, but a polyacrylonitrile or polyacrylonitrile-based copolymer containing acrylonitrile as a monomer unit is preferable. Examples of the acrylonitrile copolymerizable monomer in the polyacrylonitrile copolymer include (meth) acrylic acid, (meth) acrylic acid ester, styrene, vinyl acetate and vinylidene chloride. Specific examples thereof include styrene / acryl Acrylonitrile copolymers, styrene / butadiene / acrylonitrile copolymers, vinylidene chloride / methyl methacrylate / acrylonitrile copolymers, methyl methacrylate / acrylonitrile / methacrylonitrile copolymers, methyl methacrylate / Acrylonitrile copolymer, acrylonitrile / methacrylonitrile / itaconic acid copolymer, and the like. Of these, methyl methacrylate / acrylonitrile copolymers are preferred because they are less likely to penetrate into organic matter such as agricultural chemical active ingredients.

However, the plastic microballoons contain a gas source such as a low boiling point hydrocarbon in a thermoplastic polymer membrane material, soften the membrane material by a heat treatment, and expand the gas source to form a hollow structure inside the membrane material . Accordingly, unexpanded plastic microballoons which are supposed to be expanded by heat treatment during the manufacturing process of the final product are also available as plastic-microballoon raw materials. However, the plastic microballoon raw materials used in the production method of the present invention are not limited to minerals Since it is used by coating a fine powder, a base expanded plastic micro-balloon subjected to heat treatment is applied. The average microparticle diameter of the plastic microballoons used in the production method of the present invention is preferably 1 to 100 占 퐉, more preferably 10 to 70 占 퐉, and particularly preferably 20 to 60 占 퐉. If the average particle diameter of the plastic micro-balloons is too small, it is difficult to coat the surface of the plastic micro-balloons with an appropriate amount of the mineral fine powder to be described later. On the other hand, The pesticide composition can not withstand the work load at the time of kneading or assembly in the process of manufacturing the pesticidal composition, and the hollow structure may be broken.

The production method of the present invention is characterized by using, as a hollow body, a mineral microparticle expanded plastic microballoons having a mineral fine powder coated on the surface of the above-mentioned expanded plastic microballoons. Preferable mineral fine powders that can be used for covering the surface of the plastic microballoons include, for example, calcium carbonate, titanium oxide, talc and the like. In addition, a mineral fine powder having an average particle diameter of 0.1 to 15 mu m and a half or less of an average particle diameter of the plastic microballoons is preferable, and particularly, an average particle diameter of 1 to 12 mu m, / 5 or less is preferable.

Surprisingly, the pre-expanded plastic microballoons coated with the mineral fine powder as described above are rapidly miscible with powders such as active ingredients for pesticides, surfactants, solid carriers and the like even though they have a very small true specific gravity. Therefore, according to the production method of the present invention, since a uniform raw material mixture can be obtained in a short time mixing step, the production efficiency of the granular pesticide composition is remarkably improved, and the granular pesticide composition, And can be stably produced. In other words, the granular pesticide composition produced by the production method of the present invention is surely floated on the surface of water and becomes good in quality. Even when plastic microballoons not coated with mineral fine powder are used, homogenization of the raw material mixture can be achieved by mixing them for a long period of time at the expense of production efficiency. However, the obtained granular pesticide compositions are not suitable for application Application), it becomes long time from the water surface to collapse. The granular pesticide composition of the present invention is improved in collapsibility compared to the case of using plastic microballoons not coated with mineral fine powder, for example, the collapse time at the water surface is shortened by 10% or more, more preferably by 20% or more , It is not influenced by the wind blowing around the wrapping pavement, and there is almost no occurrence of the weakening by the ubiquitous component in the package.

The expanded plastic microballoons may be used as they are, such as those commercially available from Matsumoto Microsphere MFL series (manufactured by Matsumoto Oil Co., Ltd.), or may be blended with mineral-based fine particles, which are not coated with mineral fine powder, , And may be used as a base expansion plastic microballoons coated with a mineral fine powder. Alternatively, after expanding the plastic microballoons by heating the unexpanded plastic microballoons, the expanded plastic microballoons coated with the mineral fine particles can be obtained, and the inflated plastic microballoons and the mineral fine powders And the resulting mixture is subjected to heat treatment to swell the unexpanded plastic microballoons raw material and to attach the mineral fine powder to the outer surface of the obtained expanded plastic microballoons. In any case, when this coating step is carried out directly, it is preferable to perform coating treatment in a system in which only unexpanded plastic microballoons raw material or base expansion plastic microballoons and mineral fine powder exist. On the other hand, for example, in the process of producing the granular pesticide composition, even if all of the components constituting the pre-expanded plastic microballoons, the mineral fine powders and other granular pesticide compositions which are not coated with the mineral fine powder are mixed, The effect of the present invention can not be obtained because it is not selectively deposited on the surface but dispersed in the raw material mixture.

In the present invention, the term "coating" means a state in which mineral fine powder is attached to all or a part of the surface of the base expansion plastic microballoons.

The amount of coating on the mineral fine powder plastic microballoons is not particularly limited, but the amount of the plastic microballoons excluding the mineral fine powder on the surface of the plastic microballoons based on the total amount of the mineral fine powder expander plastic microballoons is 5 to 20% by mass . As a method for removing the mineral fine powder from the surface of the mineral fine particle expander expandable plastic microballoons, for example, a mineral fine particle expander expandable plastic microballoons are dispersed in water, and only the mineral fine particles are precipitated by removing the specific gravity difference , Followed by drying to remove moisture.

The mineral fine powder expander plastic microballoons used in the production method of the present invention may contain a very small amount of water, but the excessive water functions as a binder for coagulating the mineral plastic microballoons with the expander microballoons, It is possible to prevent rapid mixing of the mineral microparticle expanded plastic microballoons in the mixing process of the mineral microparticles. The water content of the mineral fine powder expander expandable plastic microballoons is preferably 5 mass% or less, particularly preferably 3 mass% or less.

The manufacturing method of the present invention is a method of manufacturing a hollow body (hereinafter collectively referred to as " other hollow body ") other than a plastic micro balloon or a plastic micro balloon which is not coated with a mineral fine powder in combination with a mineral fine- But the production method and the granular pesticide composition thus obtained are also included in the present invention. However, even when other hollow bodies are used in combination, it is preferable that most of the hollow bodies are made of mineral microparticle expanded plastic microballoons. Concretely, it is preferable that the amount of the mineral microparticle-expanded plastic microballoons is 50% by mass or more, preferably 70% by mass or more, more preferably 90% by mass or more, based on the whole amount of the hollow body excluding the mineral fine powder and other additives good.

The blend amount of such a hollow body is not particularly limited as long as the granular pesticide composition is the amount of the granular pesticide composition as the total amount of the hollow body, but if blended more than necessary, it becomes a loose particle and is broken during storage, transportation or use, It is preferable to contain the minimum necessary amount because there is a case that the amount of generated dust is increased and the like is not preferable. Therefore, the upper limit of the amount of the hollow bodies to be blended is generally about 30% by mass, preferably 15% by mass or less, more preferably 5% by mass or less based on the total amount of the granular pesticide composition. When the hollow body is a plastic micro-balloon, the composition can be obtained as a plastic micro-balloon body at a blending amount of 5 mass% or less. The lower limit is 0.3% by mass, and preferably 0.5% by mass or more. A blend ratio of less than 0.3% by mass may not exhibit the water surface oil repellency of the composition.

In addition, in the granular pesticide composition of the present invention, it is preferable that a small amount of water is contained in the composition in order to enhance the effect of the hollow body. The content of the water is not particularly limited, but is generally about 0.3 to 3 mass%, preferably about 0.3 to 1.5 mass%, based on the total amount of the granular pesticide composition. When the amount of water is less than 0.3% by mass, the structure tends to allow water to intrude into the composition. Therefore, once the composition is put into water, it floats on the water surface once, The above-mentioned suspension carrier must be contained, which is not preferable in some cases. If the amount of water is 3% by mass or more, the granular materials may adhere to each other and become sticky and difficult to spray, or the composition may become unfavorable, causing problems such as generation of fine powder at the time of spraying.

In the granular pesticide composition of the present invention, a method of containing a predetermined amount of water may be a method in which the composition is completely dried and then sprayed. However, in general, when the water content is measured, the composition is dried and a predetermined amount of water content The drying may be terminated. The content of water in the granular pesticide composition of the present invention can be measured using, for example, a Karl Fischer-type moisture measuring device and an infrared moisture measuring device.

In the granular pesticide composition of the present invention, a solid carrier is blended. As the solid carrier, a water-soluble carrier or a water-insoluble carrier may be used, or a combination thereof may be used. Soluble organic carrier such as organic or inorganic acid salts such as ammonium sulfate, ammonium bicarbonate, ammonium nitrate, ammonium chloride, potassium chloride, sodium sulfate, magnesium sulfate, sodium citrate, sodium carbonate and sodium hydrogencarbonate, organic acids such as citric acid and tartaric acid , Sugars such as sucrose and lactose, and urea. In addition, the water-insoluble carrier is generally a mineral fine powder, and examples thereof include clay, calcium carbonate, bentonite, talc, diatomaceous earth, calcium stearate, and white carbon.

These solid carriers may be used alone or in combination of two or more. The sum of the mixing ratios of such solid carriers is not particularly limited, but is usually 0.1 to 99.2 mass%, preferably 10 to 70 mass%, based on the total amount of the granular pesticide composition.

In the granular pesticide composition of the present invention, auxiliaries are added as other components as necessary. Examples of the auxiliary agent which is all of these components include a binder, a disintegrant, and an anticorrosive agent for active ingredients of agricultural chemicals.

Specific examples of the binder include carboxymethylcellulose sodium salt, dextrin, water-soluble starch, xanthan gum, guar gum, sucrose, polyvinylpyrrolidone, polyvinyl alcohol, polyacrylic acid sodium salt, polyoxyethylene having an average molecular weight of 6,000 to 5,000 And the like.

Specific examples of the disintegrating agent include sodium triphosphate, sodium hexametaphosphate, metal stearate, cellulose powder, dextrin, methacrylic acid ester copolymer, polyvinylpyrrolidone, polyaminocarboxylic acid chelate compound, styrene isobutylsulfonate Maleic anhydride copolymer, starch polyacrylonitrile graft copolymer, and the like.

Specific examples of the decomposition inhibitor include a drying agent such as zeolite, quicklime and magnesium oxide, an antioxidant such as a phenol compound, an amine compound, a sulfur compound or a phosphoric acid compound, an ultraviolet absorber such as a salicylic acid compound or a benzophenone compound.

These adjuvants may be used alone or in combination of two or more. When these adjuvants are incorporated, the total amount of the adjuvants is generally 0.01 to 10% by mass, preferably 0.1 to 6% by mass, based on the total amount of the granular pesticide composition.

In the granular pesticide composition of the present invention, in the case of dissolving or dispersing the agricultural chemical active ingredient, an organic solvent may be used. Examples of the organic solvent include organic solvents such as dioctyl phthalate, methyl naphthalene alkyl pyrrolidone, phenyl xylyl ethane, glycerin, alkylene glycol, machine oil, methane series hydrocarbon, fatty acid ester, polybasic acid, palm oil, soybean oil, Oils and the like can be used, but a high boiling solvent is preferable.

The organic solvent may be used alone or in combination of two or more. The total of the blending ratios of the organic solvents containing these organic solvents is generally 10 to 200 parts by weight based on 100 parts by weight of the agricultural chemical active ingredient.

The granular pesticide composition of the present invention is usually a particulate composition suspended on the water surface containing the above-mentioned components. However, each of the above-mentioned components and blending amount is preferably such that when the composition has a particle diameter of 3 mm or more, the collapse time is 30 minutes or less, It is adjusted to be within 20 minutes. If the disintegration time exceeds 30 minutes, it is undesirable because the composition is pushed to the wind. In order to reduce the influence of wind, it is preferable to control the blending amount of each component so that the portion exposed above the water surface when the composition floats on the water surface is 40% or less, preferably 20% or less of the entire composition Do.

The granular pesticide composition of the present invention itself is in accordance with a known method, except that the mineral microparticle-expanding machine expanded plastic microballoons are employed as a hollow body. In other words,

(a) mixing all the raw materials constituting the granular pesticide composition to obtain a mixture;

(b) adding a predetermined amount of water to the mixture obtained in the step (a) to knead the mixture;

(c) discharging and kneading the kneaded product obtained in the step (b) on a screen having a pore size of 3 mm or more using an extrusion granulator;

(d) drying the granules obtained in the step (c);

, The granular pesticide composition of the present invention can be obtained.

In step (a), all the raw materials constituting the granular pesticide composition including the agricultural chemical active ingredient, the surfactant, the mineral fine powder coating expandable plastic microballoons and the solid carrier are mixed. For mixing, known mixers such as a Nauta mixer and a vertical mixer can be used. The time required for this mixing depends on the performance of the mixer and the batch scale, but is usually about 30 seconds to 3 minutes.

Next, water is added to the mixture thus obtained and kneaded (step (b)). For kneading, a known kneader such as a kneader, a ribbon mixer, and a vertical mixer may be used. The amount of water to be added is not particularly limited, but it may be added in an amount of usually about 10 to 15 mass% in the mixture. This mixture is kneaded in the kneader for a predetermined time to obtain a kneaded product.

This kneaded product is discharged and assembled on a screen having a pore size of 3 mm or more, preferably 3 to 10 mm by using an extrusion granulator (step (c)), and then the obtained granulated product is dried (step (d)). The drying temperature at the time of drying the granulated product is not particularly limited, but it is about 40 to 95 캜.

As a preferable composition example of the granular pesticide composition of the present invention, for example, a composition containing an effective ingredient having a sleeping effect as a component and having a particle size of 3 to 8 mm, a specific gravity of 0.3 to 1, Collapse.

It is essential that the granular pesticide composition of the present invention has a particle size of 3 mm or more, that is, a particle size distribution of particles having a particle size of 3 mm or more of 80% or more, and particles having a particle size of 3 to 10 mm are 80% , More preferably 80% or more of the particles of 3 to 8 mm. It is possible to easily obtain a spraying area of 5 to 50% of the total silane area at a distance of 1 m or more from the rice cracker even when the preparation is sprayed from the rice cracker by making the particle size distribution. A secondary effect of setting the particle size to 3 mm or more is that the misuse can be prevented because it can be easily discriminated from the granules for seedling boxes containing a lot of particles having a grain diameter of about 0.8 mm. Even if the rice is carefully handled in a nursery box, it is possible to minimize the possibility of misuse in order to float into the water only by the preparation of the present invention.

There is no particular limitation on the method of spraying the granular pesticide composition of the present invention described above on the water surface such as a non-ionic liquid, but for example, a method of throwing a composition with a hand wearing a vinyl glove, a power sprayer, A method in which the shutter lever is instantaneously opened and closed, the method in which the shutter lever is intermittently discharged and sprayed, the method in which the shutter lever is sprayed using a scoop, the method in which the cylindrical container is shaken, Granulator), and further, a method of spraying with a radio-controlled helicopter in a muscle shape or as a spot. Alternatively, a predetermined amount of the obtained granular pesticide composition may be packed in a water-soluble film such as polyvinyl alcohol, and the so-called jumbo form may be added to the packed body by lightning or the like.

Conventionally, in the case of so-called early cultivation in which the transplanting time is early in rice planting, there is almost no occurrence of algae in the paddy field even when the granular pesticide composition is sprayed within 1 to 2 weeks after transplantation, The diffusibility is good, and a desired effect can be obtained. However, in the so-called ordinary cultivation, in which the transplanting period is from May, the water temperature rises and algae are generated at the time of spraying the pesticide. Since the algae inhibits the spread of the active ingredient of the pesticide, There are many cases that can not be obtained. Particularly, when the pesticide composition of the suspended pesticide is sprayed locally on the windless pest by the pest, the pesticide effect can not be obtained in the part where the pest is piled up. Further, even when the growth of rice grows after the order of grafting, and the rice paddy grows and the pesticide composition floating on the surface is sprayed locally, the spread of the active ingredient of the pesticide is hindered. Thus, the aerial spraying composition, which is a prerequisite for local spraying, was a composition to be sprayed when the rice seedlings were small.

On the other hand, the granular pesticide composition of the present invention can be said to be a surface-suspended granular pesticide composition having good pesticidal active ingredient diffusion and obtaining the effect of a desired pesticide even in paddy fields where algae are generated or in rice paddies grown to some extent , It is possible to uniformly disperse the active ingredients of the agricultural chemical without substantially interfering with the bioactivity at the time of spraying the pesticide, by spraying the pesticide at a specific site and in a specific area of the plant. That is, when the particle diameter of 3 mm or more of the present invention is 80% or more, it floats on the water surface and disintegrates on the water within 30 minutes. The granular pesticide composition is desorbed at a distance of 1 m or more, preferably 2 m At an area of 5 to 50%, preferably 10 to 50% of the total area of the silane, the active ingredient of the pesticide can be uniformly sprayed onto the silk screen.

Although the granular pesticide composition of the present invention can be sprayed at 50% or more of the total area of the innonneous matter, it is no problem for spraying the pesticide with abundant power, and it is preferable to spray it at an area of 50% or less. In addition, the pesticide active ingredient of the present invention can be spread well by the pesticide composition of the present invention even when the non-nong produced no algae, the non-nong produced before the transplantation, and the small non-nong produced by the rice plant.
