摘　　要：对18%百菌清·霜脲氰悬浮剂防治黄瓜霜霉病(Pseudoperonospora cubensis)田间效果进行了试验,结果表明,18%百菌清·霜脲氰悬浮剂用量为405ga.i./hm2、472.5ga.i./hm2、540ga.i./hm2时,其对黄瓜霜霉病的防效分别为61.00%、68.82%、74.05%,小区折合产量分别为33946.2kg/hm2、36709.0kg/hm2、37595.7kg/hm2,与空白对照相比分别增产7.38%、16.08%、18.88%。The efficacy ofchlorothalonil ·cymoxanil 18% SE against Pseudoperonospora cubensis in cucumber field was investigated. Field trial results showed that The efficacy of ehlorothalonil .cymoxanil 18%SE was 61.00%, 68.82% and 74.05%when applied at rate of 405 g a.i./hm^2, 472.5 g a.i./hm^2 and 540 g a.i./hm^2, respectively. The yield of cucumber was 33 946.2 kg/hm^2, 36 709.0 kg/hm^2, and 37 595.7 kg/hm^2, respectively. The yield increase was 7.38%, 16.08%, and 18.88% compared with control, respectively.
