STABLE SOLID AGRICULTURAL CHEMICAL FORMULATION

摘要

PURPOSE:To provide a stable solid agricultural chemical formulation containing a polyoxyethylene group-containing compound as a stabilizer and a benzyl ester-type synthetic pyrethroid having cyano group at alpha-position and an organic phosphate compound as active components. CONSTITUTION:A benzyl ester-type synthetic pyrethroid having cyano group at alpha-position and an organic phosphate compound are used as active components and are supported on a mineral carrier to obtain a solid agricultural chemical formulation. The formulation is stabilized with a compound having polyoxyethylene group and expressed by formula [R is H, 2-30C alkyl, 7-30C aralkyl or 7-30C alkylaryl; n is 2-50; X is H or -SO3Y (Y is cation)] (especially preferably a polyethylene glycol having an average molecular weight of 200-800). The stabilized formulation contains pyrethroid in highly stabilized state without lowering the stability of the organic phosphate compound.
