Abstract

PURPOSE:To obtain microcapsule having excellent dispersibility in an aqueous medium and low settling rate, by blending an agricultural chemical with an agent having low specific gravity and making the blend into microcapsule by interfacial polymerization or in situ polymerization. CONSTITUTION:An agricultural chemical is blended with an oil agent selected from a petroleum organic solvent, vegetable oil, animal oil and hardened oil having <=1.0 specific gravity at 20 deg.C and >=60 deg.C (760mmHg) boiling point, preferably >=8C aliphatic hydrocarbon or aromatic hydrocarbon having <=0.9 specific gravity at 20 deg.C and 100 deg.C boiling point (760mmHg) and made into microcapsule by interfacial polymerization or in situ polymerization. The ratio of the oil agent blended is preferably <=60wt.%, especially 5-50wt.% based on the agricultural chemical.
