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 present invention addresses the problem of providing a granular agrochemical composition characterized by containing an agrochemical active component, having a particle size distribution in whichparticles measuring 3 mm or more in diameter account for 80% or more, and having the property of floating on a water surface and disintegrating on the water surface within 30 minutes, the granular agrochemical composition having good disintegration properties, being easy to manufacture, having low moisture absorbency, and being easy to disperse while containing the agrochemical active component ina high concentration. The granular agrochemical composition via which the aforesaid problem is overcome: contains an agrochemical active component, a surfactant, hollow bodies measuring 1-600 [mu]m in diameter, and a solid carrier; has a particle size distribution in which particles measuring 3 mm or more in diameter account for 80% or more; and has the property of floating on a water surface anddisintegrating on the water surface within 30 minutes, wherein the granular agrochemical composition is characterized in that the particle diameter of the agrochemical active component is 10 [mu]m orgreater and is less than 1/10 the minor axis of the granular agrochemical 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...
