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 field effect of 18% Chlorothalonil and Azoxystrobin on the control of Pseudoperonospora cubensis was tested. The results showed that the dosage of 18% Chlorothalonil and Azoxystrobin was 405ga.i./hm2, 472.5ga.i./hm2,540ga.i./hm2, the control effects on cucumber downy mildew were 61.00%, 68.82% and 74.05%, respectively, and the plot equivalent yields were 33946.2kg / hm2 and 36709.0kg / hm2, respectively , 37595.7kg / hm2 respectively, which increased 7.38%, 16.08% and 18.88% respectively compared with the blank control.
