摘  要:研究了12.5%粉唑醇SC、25%戊唑醇EW对小麦白粉病的防效。结果表明,药后14 d,12.5%粉唑醇SC、25%戊唑醇EW各处理对小麦白粉病防效可达70%以上;药后30 d,12.5%粉唑醇SC较高剂量处理对小麦白粉病防效达90%以上,25%戊唑醇EW防效可达85%以上。同一剂量条件下,25%戊唑醇EW剂型防效显著优于80%戊唑醇WP剂型。试验结果表明,12.5%粉唑醇SC和25%戊唑醇EW杀菌剂能有效控制小麦白粉病。Teflubenzuron and tebueonazole were new fungicides belonging to triasoles and their controls on Blumeria graminis( DC. ) Speer was investigated in this paper. The result showed that the control effect of teflubenzuren and tebuconazole was over 70 % with each application concentration after 14 days,the control effect of teflubenzuron was over 90 % at higher concentrations and the control effect of tebuconazole was over 85 % after 30 days. Moreover,25 % tebuconazole EW had better control effect than 80 % tebuconazole WP at the same concentration. Therefore,25 % tebuconazole EW and 80 % tebuconazole WP were good fungicides to control Blumeria graminis( DC. ) Speer.
