生防菌对黄瓜白粉病的田间防效研究

Study on Field Control Effect of Biocontrol Bacteria Against Cucumber Powdery Mildew

以生防菌TY-1以及新型农药50%凯泽悬浮剂为供试药剂,于黄瓜白粉病发生初期进行了田间药效防治试验。结果表明,生防菌TY-1能降低黄瓜白粉病的发病率,防治效果达62.79%,仅次于50%凯泽悬浮剂1 200倍液处理。

The biocontrol bacteria TY-1 and the new pesticide 50% kaiser suspension were used as test reagents,and the field efficacy control experiment was carried out in the early stage of cucumber powdery mildew.The results showed that the biocontrol bacteria TY-1 could reduce the incidence of cucumber powdery mildew,and the control effect reached 62.79%,which was second only to 50% kaiser suspension 1 200 times solution.
