PURPOSE:To obtain granular agricultural chemical which is solid at normal temperature, having decreased tendency of agglomeration with time and improved storage stability, by using a lactone, especially epsilon-caprolactone as a component. CONSTITUTION:The objective granular agricultural chamical contains 100- 300pts.wt. of a lactone (especially epsilon-caprolactone) per 100pts.wt. of the active component. Since the agglomeration of granular agricultural chemicals occurs frequently when the melting point of the active component is 15-160 deg.C, the addition of lactone is most effective in the gruanular chemicals containing the active component having the above melting point. Furthermore, the granule prepared by the coating granulation process has high concentration of the active component at the surface of the granule, and the addition of lactone is extremely effective. The granular agricultural chemical having reduced aggromeration tendency with time by the addition of lactone has high flowability, and can be readily scattered in the field.
