Pesticidal composition and method for controlling pests using the same

摘要

A pesticidal composition comprising microcapsules, each microencapsulating an organophosphorus compound having a melting point of at least 15 DEG C., a proportion (A) of aromatic ring structure in microcapsule wall material being not more than 40% by weight, and a ratio of (A) to (average diameter/wall thickness) of the microcapsules being not less than 0, but not more than 0.8, causes less color change to applied area even if applied outdoors.
