Control effect of chlorfluazuron on strawberry powdery mildew in greenhouse
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 1 200 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.
