Abstract

A pesticide formulation characterized by the condensed phosphate and the water-soluble pesticide active ingredient being carried on the surface of the granulated product, which uses a wide range of water-soluble pesticide active ingredients and is easy to spray. Even if the amount used is small, the pesticide active ingredient can be quickly diffused into seedling boxes, fields and paddy fields, and quickly delivered to protected cultivated plants and pests to be controlled. can.

Description

The present invention relates to a technique for improving the elution of a poorly water-soluble pesticide active ingredient used in a pesticide preparation having a granulated product as a core.

It is desired that the amount of pesticide active ingredients used for fields and paddy fields is small due to the burden on the environment, but if the amount used is small, the pesticide active ingredients will be quickly diffused to nursery boxes, fields and paddy fields, and will be protected promptly. It is difficult to deliver to the target cultivated plants and the target pests.

In particular, when the pesticide active ingredient is sparingly soluble in water, the pesticide active ingredient may not be eluted well and the original effect of the pesticide active ingredient may not be exhibited.

To solve such problems, for example, S- (4-chlorobenzyl) N, N-diethylthiolcarbamate and 2-[(4,6-dimethoxypyrimidine-2-yl) aminocarbonylaminosulfonylmethyl] benzoic acid. An improved herbicidal composition comprising the addition of calcium carbonate to a granular composition containing a methyl ester as an active ingredient (Patent Document 1), (A) Weeding having a pyrimidinyl or triazinylcarbamoyl sulfamoyl group. An active compound, (B) a compound having a water solubility of 100 ppm or less at 20 ° C., which is effective against weeds of the family Hydrangea, (C) calcium carbonate and (D) sodium tripolyphosphate, sodium pyrophosphate or potassium pyrophosphate, or 2 An improved herbicide composition for paddy fields (Patent Document 2) characterized by containing seeds or more, (a) a pesticide active ingredient having a water solubility of 5 ppm or less at 20 ° C., and (b) an apparent specific gravity of 0. A water-floating carrier having a particle size of 100 to 2000 μm and a floating rate of 70% or more after 2 hours at 02 to 0.20, (c) tripolyphosphate, (d) alkylbenzene sulfonate and (e) et al. Agricultural chemical granules with improved dissolution into water (Patent Document 3), which is characterized by containing the carrier of the above, and a powder carrier containing water and bentonite is coated on the surface of the granule nucleus with an oily substance as a binder. Techniques such as pesticide granules (Patent Document 4), which are characterized by the above-mentioned effect, have been proposed.

Most of these technologies are related to specific poorly water-soluble pesticide active ingredients, and are related to pesticide preparations that use a wide range of poorly water-soluble pesticide active ingredients and are centered on granulated products that are easy to spray. is not it.

In particular, among the compositions described in Patent Document 2, there is a composition in which silica sand whose particle size is adjusted by sieving is used as a granule core (not a granulated product) and the above compound or the like is attached thereto. In a configuration in which the grain nuclei are not granulated, the poorly water-soluble pesticide active ingredient may not be eluted well (for example, the compound (6) used in Example 2 of Patent Document 2, that is, pyrazosulfuron ethyl. Case etc.).

As another technique, at least one alkaline or alkaline earth metal is contained in a solid-form preparation containing synthetic pyrethroid and an organic phosphate ester compound as active ingredients and supporting them on a mineral carrier. A solid pesticide-based preparation characterized by containing a weak acid salt of the above is known (Patent Document 5). However, the pharmaceutical product described in Patent Document 5 is obtained by simply mixing and pulverizing each component together with a carrier, and the stability of the above active ingredient when it is used as a wettable powder is improved, and it is as it is. It is not a technique for improving the elution rate of the water-soluble pesticide active ingredient from a formulation that is sprayed, especially a granular formulation.

Therefore, the present invention is a pesticide preparation that uses a wide range of poorly water-soluble pesticide active ingredients and is mainly composed of granulated products that can be easily sprayed. It provides a technology that can be spread to fields and paddy fields and quickly delivered to cultivated plants to be protected and pests to be controlled.

As a result of diligent research to solve the above-mentioned problems, the present inventors have found that the above-mentioned problems can be solved by supporting the condensed phosphate and the poorly water-soluble pesticide active ingredient on the surface of the granulated product, and the present invention has been made. Was completed.

That is, the present invention is a pesticide preparation characterized in that a condensed phosphate and a poorly water-soluble pesticide active ingredient are supported on the surface of a granulated product.

Further, the present invention is a method for producing the above-mentioned pesticide preparation, which comprises treating a granulated product with a condensed phosphate, a poorly water-soluble pesticide active ingredient and a binder.

Since the pesticide preparation of the present invention is a pesticide preparation having a granulated product as a core, it is easy to spray, and even if the amount used is small, the pesticide active ingredient is uniformly diffused into a nursery box, a field or a paddy field. be able to.

In the pesticide preparation of the present invention, condensed phosphate and a poorly water-soluble pesticide active ingredient are supported on the surface of the granulated product. In the present specification, the poorly soluble in water means a substance having a solubility of 500 ppm or less, preferably 100 ppm or less, particularly preferably 20 ppm or less in water at 20 ° C. Further, the pesticide active ingredient slightly soluble in water is better than the completely water-insoluble pesticide active ingredient, specifically, 0.01 ppm or more, preferably 0.05 ppm or more, and particularly preferably 0.1 ppm or more of water. Pesticide active ingredients with solubility are suitable. The solubility can be measured according to a conventional method using HPLC or the like. For example, particles of the pesticide active ingredient are dispersed in water and shaken to prepare a saturated aqueous solution of the pesticide active ingredient, and high performance liquid chromatography or the like is performed. The concentration in water can be obtained by quantitative analysis of the above, but any means can be used without limitation as long as it is a scientifically reasonable means. Further, the fact that the condensed phosphate and the water-insoluble pesticide active ingredient are supported on the surface of the granulated product means that the condensed phosphate and the water-insoluble pesticide active ingredient are supported in the form of granules (powder) on the surface of the granulated product. It may be supported or may be supported in a film form. Further, the condensed phosphate and the poorly water-soluble pesticide active ingredient may be supported by physically adhering to the surface of the granulated product, or may be supported by chemically binding to the granulated product. It may be supported on a part of the surface of the surface instead of the entire surface of the surface.

The condensed phosphate used in the pesticide preparation of the present invention is not particularly limited, and is, for example, lithium pyrophosphate, sodium pyrophosphate, potassium pyrophosphate, ammonium pyrophosphate, lithium tripolyphosphate, sodium tripolyphosphate, potassium tripolyphosphate, tripolyline. Examples thereof include ammonium acid, a salt of metaphosphoric acid having a degree of polymerization of 4 or more, and the like. Among these condensed phosphates, sodium tripolyphosphate and potassium tripolyphosphate are preferable, and sodium tripolyphosphate is particularly preferable. The blending amount of this condensed phosphate is 0.01 to 10% by mass (hereinafter, simply referred to as "%") of the pesticide preparation of the present invention, preferably 0.05 to 1%.

The poorly water-soluble pesticide active ingredient used in the pesticide preparation of the present invention is not particularly limited, and is, for example, cyantraniliprole (14.2 ppm), chloranthraniliprole (1.023 ppm), imidacloprid (480 ppm), tetranili. Prolu (1.2 ppm), (RS) -2-chloro-4-fluoro-5- [5- (trifluoromethylthio) pentyloxy] phenyl 2,2,2-trifluoroethyl sulfoxide (0.81 ppm), fluben Insecticides such as diamide (0.03 ppm) and oxazosulfyl (10.8 ppm), weeding such as fenquinotrione (17.3 ppm), fenoxasulfone (0.17 ppm) and pyroxasulfone (3.49 ppm). Examples thereof include bactericides, bactericides such as Benchavaricarb isopropyl (13.1 ppm), Penflufen (11.67 ppm), Pyribencarb (6.76 ppm) and Diclobenazox (0.36 ppm). The values in parentheses after these poorly water-soluble pesticide active ingredients indicate the solubility in water at 20 ° C. Further, these poorly water-soluble pesticide active ingredients may be used alone or in combination of two or more, and among these, insecticides and / or fungicides are preferable. The blending amount of these poorly water-soluble pesticide active ingredients is 0.1 to 10%, preferably 0.3 to 5%, of the pesticide preparation of the present invention. The size of these poorly water-soluble pesticide active ingredients is not particularly limited as long as they can be supported on the surface of the granulated product, but may be appropriately pulverized if necessary.

In the pesticide preparation of the present invention, the mass ratio of the condensed phosphate to the poorly water-soluble pesticide active ingredient is not particularly limited, but is, for example, 1: 0.1 to 10, preferably 1: 1 to 5.

In addition to the condensed phosphate and the poorly water-soluble pesticide active ingredient, the pesticide preparation of the present invention may further carry a surfactant. Such surfactants are not particularly limited, but are, for example, alkyl sulfate esters, aryl sulfonates, polyoxyethylene glycol ethers, polyhydric alcohol esters, dialkyl sulfosuccinates, polycarboxylic acids, and polyoxyethylene. Examples thereof include nonylphenyl ether and sodium lignin sulfonate. The blending amount of this surfactant is 20 to 0.01%, preferably 10 to 0.05% of the pesticide preparation of the present invention.

In addition to the above-mentioned surfactant, the pesticide preparation of the present invention may further carry other components such as a bulking agent such as clay, calcium carbonate and bentonite, and a pulverizing aid such as silica sand.

The granulated product used in the pesticide formulation of the present invention is not particularly limited as long as it is a granulated carrier. As a matter of course, the granulated product in the present specification does not include a non-granulated product such as a carrier bulk material whose particle size has been adjusted by sieving or the like. Further, the pesticide preparation of the present invention does not contain the condensed phosphate, which is generally used as a disintegrant of the granulated product, in the granulated product and supports it on the surface of the granulated product to exert its effect. be. Therefore, the granulated product used in the pesticide formulation of the present invention is either a disintegrating one containing a disintegrant (dispersed and disintegrated in water) or a non-disintegrating one containing no disintegrant (not dispersed and disintegrated in water). It does not matter which one. However, for example, when the pesticide preparation of the present invention is applied and the granulated product is disintegrated on the spot due to irrigation or the like, the concentration of the pesticide active ingredient becomes high and there is a great concern about phytotoxicity. The granulated product used for the pesticide preparation is preferably a non-disintegrating product containing no disintegrant. It is a technique known to those skilled in the art to make the granulated product non-disintegrating.

The carrier is not particularly limited as long as it can be used in pesticide preparations, and for example, minerals such as quartz, clay, silica sand, kaolinite, pyrophyllite, cericite, talc, bentonite, acidic white clay, attapulsite, zeolite, and diatomaceous clay. Kind; Inorganic salts such as calcium carbonate, barium carbonate, organic solids such as synthetic silicic acid, synthetic silicate, starch, cellulose, plant powder; plastic carriers such as polyethylene, polypropylene, polyvinylidene chloride; citric acid, succinic acid Organic solid acids such as; sugars such as sucrose, lactose; sodium sulfate, magnesium sulfate, sodium citrate, sodium carbonate, sodium hydrogencarbonate, sodium acetate, ammonium sulfate, ammonium bicarbonate, ammonium nitrate, ammonium chloride, potassium chloride, potassium heavy tartrate Such as water-soluble salts; urea, alumina, fumed silica (white carbon) and the like can be mentioned. Among the carriers, clay, kaolinite, bentonite, acidic clay, calcium carbonate, starch, ammonium sulfate, potassium chloride, and fumed silica are preferable. One of these carriers may be used alone, or two or more of these carriers may be used in combination as appropriate. When two or more kinds are used in combination, it is preferable to contain at least one or both of clay and calcium carbonate.

The method for granulating the carrier is not particularly limited as long as it is a granulation method used for agrochemical preparations, and examples thereof include extrusion granulation, rolling granulation, fluidized bed granulation, and spray drying granulation. The granulation conditions are also not particularly limited. Among these granulation methods, extrusion granulation is preferable. Extruded granulation can be performed by an extruded granulator equipped with a screen or the like. Further, after granulation, drying may be performed as appropriate.

In granulating the carrier, if desired, alkyl sulfate esters, aryl sulfonates, polyoxyethylene glycol ethers, polyhydric alcohol esters, dialkyl sulfosuccinates, polycarboxylic acids, polyoxyethylene nonylphenyl ethers, lignins. Surfactants such as sodium sulfonate; binders such as starch, alginic acid, glycerin, polyvinylpyrrolidone, polyurethane, polyethylene glycol, polypropylene glycol, polybutene, polyvinyl alcohol, arabic gum, liquid paraffin, ethylcellulose, polyvinylacetate; calcium stearate, talc , Lubricants such as silica; colorants such as dyes and pigments; auxiliary agents such as may be used.
