The present invention provides an aqueous suspended agricultural chemical composition comprising an agricultural chemical active ingredient, an alkyl naphthalene sulfonate formalin condensate and one or two or more compounds selected from the group consisting of an alkyl sulfate, a polyoxyalkylene alkyl ether sulfate, an alkyl phosphoric acid and a salt thereof, a polyoxyalkylene alkyl ether phosphoric acid and a salt thereof, and a polyoxyalkylene alkyl ether acetic acid and a salt thereof. The aqueous suspended agricultural chemical composition suppresses the crystal growth of the agricultural chemical active ingredient, and has an excellent effect on pest control and an excellent storage stability.
