Abstract:
Using 15-year-old grape variety ‘Meiguixiang’ as material,a field experiment was conducted,the control effecency of 40% Dimethomorph?Azoxystrobin on grape downy mildew was studied.The results showed that 7 days after spraying Dimethomorph?Azoxystrobin,the effeciency of tested fungicides at active ingredient dosage of 200 mg/kg,160 mg/kg were all equaled to the control fungicide azoxystrobin SC at active ingredient dosage of 166.7 mg/kg,with no significant difference between them.14 days after spraying Dimethomorph?Azoxystrobin,the efficiency of tested fungicides at active ingredient dosage of 200 mg/kg was equal to the control fungicide,azoxystrobin SC at active ingredient dosage of 166.7 mg/kg,and the efficiency of tested fungicide at active ingredient dosage of 160 mg/kg was equal to the control fungicide,the 50% wettable enoyl morpholine at active ingredient dosage of 200 mg/kg.
