摘　　要：近年来,由于大棚草莓白粉病原菌的抗性增强,药剂防效减退。因此,本研究比较了不同类型杀菌剂的田间防效,以期为延缓白粉病病原菌的抗性发展,为田间用药提供指导。本研究选用新型的三唑类化学杀菌剂,400 g·L^(-1)氯氟醚菌唑悬浮剂进行大棚草莓白粉病田间药效比对试验。结果表明,400 g·L^(-1)氯氟醚菌唑1 200倍稀释液防治效果最好,药后14 d对白粉病的防治效果能达到90%以上,药后21 d的防治效果达到85%以上,可作为防治大棚草莓白粉病和交替使用的优选药剂,为大棚草莓白粉病的有效防治提供依据。In recent years,due to the increased resistance of strawberry powdery mildew pathogens in greenhouses,the efficacy of pesticide control has decreased.Therefore,this reseach compared the field efficacy of different types of fungicides in order to delay the development of resistance to powdery mildew pathogens and provide guidance for field medication.This study selected a new type of triazole chemical fungicide,400 g·L^(-1) chlorfluazuron suspension,for field efficacy comparison of strawberry powdery mildew in greenhouses.The results showed that the 1200 fold dilution of 400 g·L^(-1) chlorfluazuron had the best control effect on powdery mildew,with a control effect of over 90%after 14 days of treatment and over 85%after 21 days of treatment.It can be used as a preferred agent for controlling strawberry powdery mildew in greenhouses and for alternate use,providing a basis for effective control of strawberry powdery mildew in greenhouses.
