Pesticide active ingredient such as asinonapyr, non-polar solvent, LogPow value less than 1.6 polar solvent, and nonionic surfactant having polyoxyethylene group are contained, and the total amount of pesticide active ingredient and non-polar solvent is The LogPow value is 1.0 to 1.6 parts by weight with respect to 1 part by weight of the total amount of the polar solvent and the nonionic surfactant having a polyoxyethylene group, and the anionic surfactant is added. A pesticide emulsion composition is provided that is substantially free of. According to the agricultural chemical emulsion composition of the present invention, it is possible to obtain good emulsifiability even when diluted with water having high hardness.アシノナピルなどの農薬活性成分、非極性溶媒、LogPow値が１．６以下の極性溶媒、及びポリオキシエチレン基を有するノニオン界面活性剤を含有し、農薬活性成分と非極性溶媒との合計量が、LogPow値が１．６以下の極性溶媒とポリオキシエチレン基を有するノニオン界面活性剤との合計量１重量部に対して、１．０～１．６重量部であり、且つアニオン界面活性剤を実質的に含有しない、農薬乳剤組成物が提供される。本発明による農薬乳剤組成物によれば、高硬度の水で希釈した時でも良好な乳化性を得ることができる。
