PROBLEM TO BE SOLVED: To provide a method for continuously manufacturing a dispersion that contains a pest control ingredient.SOLUTION: The method for continuously manufacturing the dispersion includes: a process to disperse a solution in a dispersion medium by stirring the solution and the dispersion medium in a primary dispersion tank while continuously supplying the solution and the dispersion medium to the primary dispersion tank, the solution being obtained by dissolving the pest control ingredient to a water-immiscible organic solvent and the dispersion medium consisting of water or an aqueous solution containing an alcohol and a process for stirring the primary dispersion continuously discharged from the primary dispersion tank in a secondary dispersion tank until a dispersion state becomes stationary while continuously supplying the primary dispersion to the secondary dispersion tank.COPYRIGHT: (C)2013,JPO&INPIT【課題】有害生物防除成分を含有する分散液を連続的に製造する方法を提供する。【解決手段】水非混和性の有機溶媒に有害生物防除成分を溶解させた溶液と、アルコールを含む水溶液又は水からなる分散媒とを、一次分散槽内に連続的に供給しながら、前記溶液と前記分散媒とを一次分散槽内で撹拌することにより、前記溶液を前記分散媒中に分散させる工程と、一次分散槽から連続的に排出される一次分散液を、二次分散槽に連続的に供給しながら、分散状態が定常になるまで二次分散槽内で撹拌する工程とを含むことを特徴とする。【選択図】図4
