| 摘 要： | 选用6种杀菌剂对黄瓜白粉病进行防治试验，结果表明，第3次药后，50%醚菌酯水分散粒剂3600倍液和25%戊唑醇水乳剂1800倍液处理的防效均达80.00%以上，但25%戊唑醇水乳剂1800倍液处理出现新叶生长不良症状，不推荐使用；25%嘧菌酯悬浮剂900倍液和40%氟硅唑乳油8000倍液处理的防效也均达70.00%以上，防治效果理想。结果显示50%醚菌酯水分散粒剂、25%嘧菌酯悬浮剂和40%氟硅唑乳油适用于黄瓜白粉病防治。

Effects of Six Fungicides on Cucumber Powdery Mildew |
| |
| Abstract: | Field experiments were conducted with 6 selected fungicides against powdery mildew on cucumber. The results show that the control effect of kresoxim 50% WG and tebuconazole 25% EW has reached 80.00% or more at 7 d after the third appli-cation. However, Tebuconazole 25% EW produced bad symptom to new leaves growth, so it was not recommended. The effect of Azoxystrobin 25% SC and Flusilazole 40% EC has reached above 70.00%. As a result, kresoxim 50% WG, Azoxystrobin 25% SC and Flusilazole 40% EC can be used for control powdery mildew on cucumber. |
