PROBLEM TO BE SOLVED: To provide a solid agrochemical composition having excellent safety to the environment, scracely having the problems of powdering and bleeding of an agrochemically active ingredient while containing the agrochemically active ingredient in a high concentration, and further having excellent residual effects of the agrochemically active ingredient.SOLUTION: This solid agrochemical composition comprises a broken product of fibrous crops having high oil absorbency, and the agrochemically active ingredient liquid at normal temperature or a liquid material obtained by dissolving or dispersing the agrochemically active ingredient in a liquid medium. The method for producing the solid agrochemical composition comprises impregnating the broken product of the fibrous crops with the agrochemically active ingredient liquid at the normal temperature or the liquid material obtained by dissolving or dispersing the agrochemically active ingredient in the liquid medium, and forming the resultant product into a powder shape, a granular shape or a tablet shape.COPYRIGHT: (C)2002,JPO【課題】 環境に対する安全性に優れ、農薬活性成分を高濃度で含有しながら、農薬活性成分の粉末化や、染み出しの問題がなく、かつ農薬活性成分の残効性も優れた固体農薬組成物を提供すること。【解決手段】 吸油性の高い繊維作物の破断物と、常温で液体の農薬活性成分または農薬活性成分を液体溶媒に溶解もしくは分散させた液状物とを含有する固体農薬組成物並びに常温で液体の農薬活性成分または農薬活性成分を液体溶媒に溶解もしくは分散させた液状物を、吸油性の高い繊維作物の破断物に含浸させた後、これを粉末状、粒状または錠剤状の形態とする当該固体農薬組成物の製造方法。
