FORMULATION FOR WATER SURFACE APPLICATION

摘要

PROBLEM TO BE SOLVED: To obtain a preparation for water surface application capable of evenly spreading an agrochemical active ingredient to the surface of the whole paddy water, having controlled elution. SOLUTION: This agrochemical preparation for water surface application is obtained by supporting and coating a granular composition comprising a slightly water-soluble agrochemical active ingredient, a dialkyl succinate and a ligninsulfonate with a granule nucleus of baked pumice having <1 apparent specific gravity and about 50μm to about 1,400μm particle diameter by using a mixture of a vegetable oil and a surfactant and controls elution of the agrochemical active ingredient.
