摘要：

Disclosed is a coated granular agricultural chemical which has a coating film of a urethane resin obtained by reacting a polyisocyanate containing an aromatic polyisocyanate with a polyol containing a polycaprolactone polyol. In this coated granular agricultural chemical, the weight ratio between the polyisocyanate and the polyol is from 5:95 to 40:60. This coated granule exhibits a stable performance in suppressing dissolution of the agricultural chemical active ingredient, and thus is useful as a coated agricultural chemical granule or the like.
