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.

摘要： There is disclosed an insect growth regulator composition comprising (a) an insect growth-regulating active ingredient and, if necessary, another insecticidal active ingredient, (b) an organic substance having a solubility of not greater than 2% in water at 20.degree. C. and a melting point of 35.degree. through 100.degree. C., and (c) a glycol selected from the group having a melting point of 35.degree. through 100.degree. C. and consisting of polyethylene glycol, polyoxyethylene polyoxypropylene glycol, polyoxyethylene polyoxybutylene glycol, and polyoxyethylene polyoxypropylene polyoxybutylene glycol, wherein the weight of the constituent (b) is equal to or greater than 3% based on the total weight, and a sum of the weight of the constituent (b) and the weight of the constituent (c) ranges from 20 to 98% based on the total weight, the constituent (b) and the constituent (c) being molten and then cooled to be solidified in manufacturing process of the insect growth regulator composition. The composition of the invention is the labor- and cost-saving composition because it releases an active ingredient gradually, and exterminates harmful and/or offensive pests and prevent the breeding thereof in water systems over a long time.
