In order to study the better formula of 35%carbendazim and azoxystrobin suspension concentrates, the formula was developed with the method of wet milling, and the surfactant selection was conducted with the orthogonal design. The results showed that the most reasonable composition consisted of carbendazim 30.0%, azoxystrobin 5.0%, NNO 2.0%, 600#4.0%, BY140 3.0%, xanthan gum 0.1%, glycol 2.0%, octanol 0.5%and water, and the experimental results showed that the suspension rate of this product was over 98%, the decomposition rate of the active ingredient was less than 3% at (54 ± 2)℃ with 14 days, the characteristics conformed to the requirements for the product, the field effect was 92.76%when used as 1500 g/hm2 to control powdery mildew of strawberry.
