Abstract
A coated granule is obtained by coating a bioactive substance-containing granule with a urethane resin obtained by reaction of an aromatic diisocyanate with a polyol mixture containing a polyesterpolyol and a C2-C8 polymethylene glycol, wherein the molar ratio of the polyesterpolyol to the polymethylene glycol is 1:20 to 20:1. The granule is capable of controlling elution of the bioactive substance appropriately, and the urethane resin forming the coating film shows degradability in soil.
