Abstract
An object of the present invention is to provide an agricultural chemical formulation which is able to control release of an agricultural chemical active ingredient. This agricultural chemical formulation includes a composition, containing an agricultural chemical active ingredient, styrene-maleic anhydride copolymer or mixture of styrene-maleic anhydride copolymer and polymer having repeating units derived from rosin or derivative thereof or salicylic acid or derivative thereof, and a release controller (a water-soluble polymer, a hydrophobically-treated silicon oxide, or a surfactant), forming a compatible state or matrix.
