PROBLEM TO BE SOLVED: To provide an agrochemical granular composition producible by a simple method, having good fluidity without dusting by peeling and further scarcely recognizing peeling of an agrochemical active ingredient, etc., even in application using a power sprayer.SOLUTION: This agrochemical granular composition is obtained by impregnating an oil nonabsorbing granular carrier together with a baked ultrafine particulate amorphous silicon dioxide having &le5% equilibrium moisture content and &le3 &mum average particle diameter with O,O-diethyl O-2-isopropyl-6- methylpyrimidin-4-yl phosphorothioate and bonding the O,O-diethyl O-2- isopropyl-6-methylpyrimidin-4-yl phosphorothioate thereto. The method for producing the agrochemical granular composition is provided.COPYRIGHT: (C)2003,JPO【解決手段】 O,O-ジエチル-O-2-イソプロピル-6-メチルピリミジン-4-イルホスホロチオエートを、平衡水分含量5%以下、且つ平均粒径3ミクロン以下の焼成された超微粒子非晶質二酸化ケイ素と共に非吸油性粒状担体に含浸接着させてなる農薬粒状組成物及びその製造方法。【効果】 本発明の農薬粒状組成物は、簡便な方法で製造することができ、流動性が良好で剥離による粉立ちもなく、更に動力散布機を用いた施用においても農薬活性成分等の剥離は殆ど認められない。
