STABILIZED PESTICIDE COMPOSITION

PURPOSE:To provide the titled composition obtained by adding sulfosalicylic acid as a stabilizer to a pesticide containing tricyclazole and an organophosphate compound as active components, thereby suppressing the chemical reaction between both active components with only a small amount of the stabilizer without lowering the activity of the active components. CONSTITUTION:A pesticide containing (A) 5-methyl-1,2,4-triazolo(3,4-b)benzothiazole (tricyclazole) and (B) an organophosphate compound such as S-1,2-bis (ethoxycarbonyl)-ethyl-O,O-dimethyldithiophosphoric acid ester (malathion), etc. is added with (C) sulfosalicylic acid as a stabilizer to suppress the lowering of the activity caused by the reaction of the active components A and B. The weight ratios of the components B and C to A are 2:1-1:10 and 10:0.5-1:10, respectively. Since the component C exhibits the stabilizing effect at a low dose compared with conventional stabilizer, the phytotoxicity of acids can be mitigated.
