【Task】 An object of the present invention is to provide a release-controlled granule that maintains the release of the pesticide active ingredient contained in the granule for a long period of time while suppressing the initial release by a new technique. In particular, it is an object of the present invention to stably formulate a pesticide active ingredient which has a high vapor pressure and volatilizes by heating and drying or distilling under reduced pressure into a release-controlled granule. SOLUTION: As a result of diligent studies to solve the above problems, the present inventors have impregnated the oil-absorbing nuclei (c) with a mixture containing the pesticide active ingredient (a) and the reaction-curable epoxy resin (b). The invention was completed by finding that the controlled pesticide granules can solve the above problems.
