PROBLEM TO BE SOLVED: To provide a sustained-release granule that maintains the long-term elution of an agrochemical active ingredient contained in a granule while suppressing the initial elution thereof, by a new technique.SOLUTION: A coated granular agrochemical composition is characterized in that a granular mineral carrier is used as a granule core, a liquid wax that is melted by heating is added thereto for mixing, and with it used as a binder, a powdery agrochemical active ingredient is made to cover it.COPYRIGHT: (C)2016,JPO&INPIT【課題】本発明の課題は、新たな技術により、粒剤に含有された農薬活性成分を初期の溶出を抑えつつ長期間の溶出を保つ徐放性粒剤を提供することである。【解決手段】粒状鉱物担体を粒核とし、これに熱で溶融させた液体状のワックスを加え混合し、これをバインダーとして粉末状の農薬活性成分を被覆させることを特徴とする被覆粒状農薬組成物。【選択図】なし
