Abstract:: Taking the seeds of “Hongxiaopian” watermelon as the material,10% ZJ0712 SC was selected to prevent watermelon powdery mildew，compared with 250 g/L hexaconazole SC，and the disease index and control effect by 7 or 14 days after application were investigated.The results showed that the drug 14 days after overall than seven days after the drug efficacy was better，and 14 days after treatment，the control effect of 10% ZJ0712 SC 1 500 times was the highest，with its control efficiency 93.90%，followed by 2 000 times，the control efficiency of 90.68%，and two processing within 0.1 degree of confidence in a significant difference；7 days after treatment，the control effect of 10% ZJ0712 SC 1 500 times also reached 84.61%.Hexaconazole SC has been compared to alcohol and 10% ZJ0712 SC its efficacy was poor，14 days after treatment，the control effect was only 61.68%.10% ZJ0712 SC 1 500 times also had the highest yield of 54.20%，250 g/L suspension concentrate hexaconazole yield was only 1.58%.
