PURPOSE:The titled composition having improved long-term shelf stability, obtained by adding a specific hydrocarbon to an agricultural chemical composition comprising an agricultural chemical substance having a melting point of >=a specific temperature and a specific solubility in the hydrocarbon as an active ingredient. CONSTITUTION:A agricultural chemical having >=0 deg.C melting point and >=10wt% solubility in a hydrocarbon (e.g., 2-sec-butylphenyl N-methylcarbamate) shown by the formula (X1, X2, Y1, Y2, Z1 and Z2 are H or <=2C alkyl; R1 and R2 are H or CH3; n is 0 or 1) at 0 deg.C is dissolved in the hydrocarbon shown by the formula, dispersed into water by the use of a dispersant and a thickening agent is used to give the aimed composition having raised suspension stability. This composition has neither crystal growth nor crystal precipitation at all. The amount of the hydrocarbon shown by the formula added is 0.1-10pts.wt. based on 1pt.wt. agricultural chemical substance.
