摘要： The water dispersible granule of the present invention is obtained by mixing a pesticide having a melting point of not more than 70.degree. C., a calcined product of precipitated hydrated silicon dioxide and a surface active agent, and granulating the resulting mixture by the wet granulation method or compaction method. This water dispersible granule is an excellent formulation of which the physical properties such as disintegrability-in-water, dispersibility, suspensibility, storage stability, etc. are good, and which is free from dust-scattering and is capable of being measured by volume.
