Problems solved by technology

On the other hand, for the agrochemical composition compounded with a large amount of surfactant, when the raw materials are kneaded, it becomes a sticky mass with very high viscosity, and it is difficult to manufacture by extrusion granulation. Since it becomes a pesticide composition that is easy to absorb moisture, it hinders spreading, etc., and there are physical restrictions on the amount of surfactants to be blended.
Therefore, the content of the pesticide active ingredient in the pesticide composition will naturally also be limited

Embodiment 1

[0081] Pesticide active ingredient mixture (particle size 20.2 μm) mixed with 2 parts of Pyrimisulfan, 12 parts of Fenquinotrione and 12 parts of Metrazen, 5 parts of arylsulfonate formaldehyde condensate, 3 parts of arylsulfonate, polyacrylate 3 parts, 5 parts of phosphoric acid cross-linked starch, 2 parts of polyoxyalkylene alkynyl glycol ether, 2 parts of plastic balls, 15 parts of diatomaceous earth, 5 parts of bentonite and 34 parts of clay, after adding a specified amount of water for kneading , while passing through a sieve with a mesh diameter of 3 mm to extrude and granulate, cut into a length of about 6 mm with a scraper. Put the obtained granules into a horizontally placed drum, rotate the drum to roll the granules until it becomes a shape made of a curved surface, then dry with hot air and sieve to obtain a pesticide containing 26% by mass of the active ingredient. A granular pesticide composition with a short diameter of 3mm. The granular pesticide composition h...

Embodiment 2

[0083] Mixture of 2 parts of Pyrimisulfan, 8 parts of Fenoxasulfone and 12 parts of bicyclic sulcotrione (particle size 14.1 μm), 2 parts of aryl sulfonate, 2 parts of polyacrylate, 1 part of carboxymethyl cellulose, Phosphoric acid cross-linked starch 5 parts, polyoxyalkylene alkynyl glycol ether 2 parts, polyalkylene glycol 3 parts, plastic ball 2 parts, diatomaceous earth 15 parts, bentonite 5 parts, clay 41 parts, adding regulations After kneading with a certain amount of water, it was cut into lengths of about 10 mm with a scraper while extruding and granulating through a sieve with a mesh diameter of 5 mm. The granulated matter obtained is put into a horizontally placed drum, and the drum is rotated to roll the granulated matter until it becomes an outer shape made of a curved surface, and then dried with hot air to obtain a 5 mm short diameter containing 22% by mass of the pesticide active ingredient. granular pesticide composition. The granular pesticide composition h...

Embodiment 3

[0085] Mix 48 parts of pyroquinone (particle size 17.7 μm), 8 parts of aryl sulfonate, 1 part of polyoxyalkylene aryl ether sulfate, 1 part of polyoxyalkylene alkyl ether, polyoxyalkylene 2 parts of alkynyl glycol ether, 3 parts of bentonite, 1 part of urea, 3 parts of dextrin, 1 part of plastic ball and 32 parts of calcium carbonate, after adding a specified amount of water for kneading, extrude through a screen with a mesh diameter of 5mm Granulate and cut into lengths of about 10 mm with a spatula on one side. Put the obtained granulate into a horizontally placed drum, rotate the drum to roll the granulate until it becomes an outer shape made of a curved surface, and then dry it with hot air to obtain a 5 mm short diameter containing 48% by mass of the pesticide active ingredient. granular pesticide composition. The granular pesticide composition has a particle size distribution in which particles with a particle diameter of 3 mm or more account for more than 80%, has the ...

Abstract

The object of the present invention is to provide a granular pesticide composition, which is characterized in that it contains pesticide active ingredients, has a particle size distribution in which particles with a particle diameter of 3 mm or more account for 80% or more, and has the property of floating on the water surface, and within 30 minutes. Disintegrates on the surface of water. Although the granular pesticide composition contains the pesticide active ingredient in a high concentration, it has good disintegration, is easy to manufacture, has low hygroscopicity, and is easy to spread. The granular pesticide composition used to solve this problem contains pesticide active ingredients, a surfactant, a hollow body with a particle size of 1-600 μm, and a solid carrier, and has a particle size distribution and a floating structure in which particles with a particle size of 3 mm or more account for 80% or more. A granular pesticide composition that disintegrates on water within 30 minutes, wherein the particle diameter of the pesticide active ingredient is 10 μm or more and less than 1 / 10 of the short diameter of the granular pesticide composition .

Description

technical field [0001] The present invention relates to a water surface planktonic large granular agrochemical composition, and more specifically, to a water surface plankable large granular agrochemical composition capable of uniformly diffusing a pesticide active ingredient by locally and directly spraying a small amount on the water surface of a paddy field or the like. Background technique [0002] Conventionally, agricultural chemical compositions used in paddy fields etc. are generally granules, powders, emulsions, wettable powders, and suspension concentrates. Among these agrochemical compositions, granules and powders are usually sprayed in an amount of 1 to 4 kg in 10a paddy fields without diluting them in water. In recent years, labor-saving spraying of agrochemicals has been advocated. In response to this strategy, improvements in agrochemical compositions are being sought The amount of sprayed pesticide composition can be reduced by reducing the content of the ac...
