| Abstract: | An field experiment was conducted to determine the efficacy of sulfur 50% SC for control cucumber powdery mildew.Seven days after the first treatment with sulfur 50%SC at application rate of 1 125,1 312.5 and 1 500 g ha-1,the control efficacy was 60.83%,66.36%,and 74.84%,respectively.The result showed that 50% Sulfur SC could control cucumber powdery mildew in a low incidence and the most effective concentration was 1 500 g ha-1.The efficacy,10 days after the second treatment,was 73.95%,77.46%,and 82.%,resp... |
