ABSTRACT:
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.
