PROBLEM TO BE SOLVED: To prepare a solid composition including stabilized agrochemicals, improved in stability by including a specific compound and an organic acid consisting of a carboxylic acid and/or an organic phosphoric acid. SOLUTION: This solid composition including stabilized agrochemicals is prepared by including (A) a compound of the formula [Q is a (substituted) condensed heterocyclic group having a nitrogen atom at its bridge head; W is O or S; R1 and R2 are each an alkyl, an alkoxy or a halogen; Z is CH or N] or its salt, e.g. 1-(2-chloroimidazo[1,2-a]pyridin-3-ylsulfonyl)-3-(4,6- dimethoxypyrimidin-2-yl)urea and (B) (i) a carboxylic acid and/or (ii) an organic acid of an organic phosphoric acid, or its salt. It is pref. that the ingredient(i) is 14-20C (un)saturated fatty acid such as palmitic acid, oleic acid, stearic acid, tall oil fatty acids (Hartall), or the like, tricarboxylic acid such as citric acid, acetic acid, or the like and that the ingredient(ii) is potassium acetate, sodium citrate, sodium oleate, or the like.
