An object of the present invention is to provide a technique for producing a microcapsule containing a pesticidal compound in a fatty acid ester such as methyl O-acetylricinoleate, which delays the release timing of the pesticidal compound as compared to a conventional microcapsule. Provided is a method for producing a microcapsule, which comprises:
(1) keeping a mixture of a pesticidal compound, a compound represented by formula (I):
wherein X represents —CH2—CH2— or —CH═CH—, R1 represents a C1-C4 alkyl group, and R2 represents a C1-C4 alkyl group, and a polyisocyanate at 20 to 60° C. for 3 hours or more;
(2) adding the mixture to water containing a polyol or a polyamine to prepare liquid droplets in the water; and
(3) forming a film of polyurethane or polyurea around the droplets.
