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.
