The present invention contains an agrochemical active ingredient, has a particle size distribution of 80% or more of particles having a particle size of 3 mm or more, and has a property of floating on the water surface, and is a granule characterized by collapsing on the water surface within 30 minutes An object of the present invention is to provide a granular agrochemical composition which has good disintegration, is easy to manufacture, has low hygroscopicity and is easy to disperse, while containing a high concentration of an agrochemical active ingredient in the agrochemical composition. The granular agrochemical composition that has solved the problem contains an agrochemical active ingredient, a surfactant, a hollow body having a particle diameter of 1 to 600 μm, and a solid carrier, and 80% of the particles having a particle diameter of 3 mm or more. A granular agrochemical composition having the particle size distribution as described above and a property of floating on the water surface and disintegrating on the water surface within 30 minutes, wherein the particle diameter of the agrochemical active ingredient is 10 μm or more and the granular agrochemical composition has a short diameter It is less than 1/10.本発明は、農薬活性成分を含有し、粒径３ｍｍ以上のものが８０％以上である粒度分布と水面に浮遊する性質を有し、かつ３０分以内に水面で崩壊することを特徴とする粒状農薬組成物において、農薬活性成分を高濃度で含有しながら、崩壊性が良好であり、製造しやすく、低吸湿性で散布しやすい粒状農薬組成物を提供することを課題とする。 当該課題を解決した粒状農薬組成物は、農薬活性成分と、界面活性剤と、粒子径が１－６００μｍの中空体と、固体担体とを含有してなり、粒径３ｍｍ以上のものが８０％以上である粒度分布と、水面に浮遊し、かつ３０分以内に水面で崩壊する性質を有する粒状農薬組成物であって、前記農薬活性成分の粒子径が１０μｍ以上かつ粒状農薬組成物短径の１／１０未満であることを特徴とする。
