Abstract:
The field control effects of 10 fungicides on strawberry powdery mildew and their effects on chlorophyll synthesis,superoxide dismutase activity and peroxidase activity were studied with chlorothalonil and water as control,in order to provide theoretical basis for controlling strawberry powdery mildew in field.The results showed that different fungicides had different control effects on strawberry powdery mildew.The control effects of oxazolane,pyrimidine and pyraclostrobin on strawberry powdery mildew were good and stable.After the third spraying for 6 days,the control effects were 30.86% and 28.22% respectively.Through the determination to the strawberry leaf physiological index.The chlorophyll and activities of superoxide dismutase and peroxidase of strawberry leaves were not inhibited by oxazolane,pyrimidine,pyraclostrobin,tetrafluoro,myclobutanil and trifloxystrobin,which were higher than CK1 treatment.By contrast,the control effect of oxazolane,pyrimidine,pyraclostrobin,tetrafluoro,myclobutanil and trifloxystrobin was stable and safe,and it could be used to control strawberry powdery mildew in greenhouse in Xichang area.
