针对南瓜白粉病菌对三唑类农药产生抗药性的问题,进行了几种新药剂防治大棚南瓜白粉病的防效筛选试验。试验结果表明,乙嘧酚、硫磺、己唑醇对南瓜白粉病有较好的防治效果,其中乙嘧酚防效最高,达到92.82%,可作为首选药剂,与其他农药配合使用。
In order to solve the problem of Oidium sp.showing resistance against triazole fungicides,we carried out the trail to screen out effective fungicides against the powdery mildew of pumpkin in greenhouse.The results showed that ethirimol,kumulus and hexaconazole had better control effects against the powdery mildew of pumpkin,and ethirimol possessed the highest control efficiency of 92.82%,so it was the best fungicide using together with other fungicides to control powdery mildew of pumpkin.
