Disclosed is an agricultural chemical composition in the form of an aqueous suspension, which comprises fine particles of a water-insoluble physiologically active substance having a melting point of 15.degree. to 70.degree. C., which are stably dispersed in water by a water-soluble or water-dispersible polymer comprising at least one monomer selected from the group consisting of unsaturated carboxylic acids and derivatives thereof as the indispensable component, as a dispersant, and a phthalic acid ester as an agent for preventing precipitation of crystals. In this agricultural chemical composition, the phthalic acid ester bleeds on the surface of the physiologically active substance to modify the surface, and the storage stability of the composition in the form of a suspension is highly improved.
