摘　　要：根据水乳剂形成的机理,选用合适的表面活性剂、助溶剂等,研究了30%乙嘧酚磺酸酯·苯醚甲环唑水乳剂的制备方法,并对其进行了性能测定和应用研究。试验表明,30%乙嘧酚磺酸酯·苯醚甲环唑水乳剂贮前、贮后的外观稳定,不结块、不析水、不析油,且有效成分乙嘧酚磺酸酯和苯醚甲环唑化学稳定性好,热贮分解率在5%以下。另外,30%乙嘧酚磺酸酯·苯醚甲环唑水乳剂防治黄瓜白粉病效果优异,同效果好于有效成分含量相同的乳油产品。According to the mechanism of EW, choose appropriate pesticide adjuvants such as surfactant, cosolvents etc., examine the formula of 30% bupirimate·difenoconazole EW and conduct performance measurement and application research. The experiment shows that the bupirimate·difenoconazole 30% EW has the following advantages before and after storage： stable appearance, no-caking, low dialysis ratio of water and oil and no delamination and good chemical stability. Its decomposition rate is less than 5% under the condition of hot storage. The result also shows less than 3.5% breakdown at 54℃. Moreover, the bupirimate·difenoconazole 30% EW has good control effect on cucumber powdery mildew. It shows better disease control than EC formulation at the same active ingredient content.
