Pesticidal Composition

Abstract

A coated pesticidal granule obtained by aggregating a powdery pesticide with a thermosetting resin is capable of enabling a pesticidal active ingredient to be controlled-released. Further, the controlled-release pesticidal granule can be produced by mixing a powdery pesticide with a first liquid component serving as a raw material for a thermosetting resin, a process of adding a second liquid component serving as a raw material for a thermosetting resin, and then making the first liquid component react with the second liquid component to produce a thermosetting resin.
