摘要
以15a生葡萄品种"玫瑰香"为试材,通过田间小区试验研究了40%烯酰吗啉·嘧菌酯悬浮剂对葡萄霜霉病的防治效果。结果表明:药后7d,供试药剂有效成分200、160mg/kg处理的防效与对照药剂250g/L嘧菌酯悬浮剂有效成分166.7mg/kg处理的防效相当;药后14d,供试药剂有效成分200mg/kg处理的防效与对照药剂250g/L嘧菌酯悬浮剂有效成分166.7mg/kg处理的防效相当,供试药剂有效成分160mg/kg处理的防效与对照药剂50%烯酰吗啉可湿性粉剂有效成分200mg/kg处理的防效相当。
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.
