PURPOSE:A stabilized agricultural chemical composition not lowering effectiveness of active components, suppressing chemical reactions between the active components, obtained by adding a specific stabilizer to an agricultural chemical comprising tricyclazole and an organic phosphoric ester as active ingredients. CONSTITUTION:An agricultural chemical comprising tricylazole [=5-methyl-1,2,4- triazolo(3,4-b)benzothiazole] which is a fungicide and shows excellent effects on blast of rice plants and an organic phosphoric ester such as O-(4-nitro-m- tolyl)-O,O-dimethylthiophosphoric ester, etc., as active ingredients the blended with a magnesium salt such as magnesium sulfate, magnesium nitrate, magnesium phosphate, or magnesium acetate and/or magnesium halide such as magnesium chloride, etc., as a stabilizer. The amount of the stabilizer blended is of weight ratio of tricyclazole, preferably of 5:1-1:5. EFFECT:The amount of the stabilizer blended is small and phytotoxicity with an acid can be alleviated.
