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。
The effects of 40% dimethomyl azoxystrobin on the prevention and treatment of grape downy mildew were studied in a field plot experiment with 15a raw grape variety “Rosewood” as test material. The results showed that the control effect of 200 and 160 mg / kg of the active ingredient of the tested drug was equivalent to that of the control agent of 166.7 mg / kg of the active ingredient of 250g / L azoxystrobin suspension 7 d after the drug treatment; The control efficacy of the active ingredient of 200mg / kg is equivalent to the control effect of the active ingredient of the azoxystrobin 250g / L azoxystrobin suspension 166.7mg / kg, and the control efficacy of the active ingredient 160mg / kg is 50% Dimethomorph wettable powder active ingredient 200mg / kg treatment control effect.
