摘要
田间测定了几种生物农药与烯酰吗啉联合应用对葡萄霜霉病的防治效果。结果表明,6%阿泰灵可湿性粉剂1 000倍液与40%烯酰吗啉悬浮剂1 000倍液联合应用对葡萄霜霉病的防治效果较好,防效达82.5%;0.5%氨基寡糖素水剂500倍液与40%烯酰吗啉悬浮剂1 000倍液联合应用对霜霉病的防治效果次之,防效为80.2%。阿泰灵、氨基寡糖素与化学农药烯酰吗啉联合应用对葡萄霜霉病的防效虽低于保护性杀菌剂代森锰锌与烯酰吗啉联合使用的效果(94.4%),但减少了化学农药代森锰锌的使用次数,可供葡萄霜霉病化学农药减量化防治参考。
The control effect of several bio-pesticides combined with dimethomorph on grape downy mildew was determined in the field. The results showed that the combination of 6% atailing WP 1000 times liquid and 40% dimethomorph SE 1000 times liquid had the better control effect on downy mildew,the control effect was 82.5%. The control effect of 0.5% oligochitsan AS 500 times liquid combined with 40% dimethomorph SE1000 times liquid on downy mildew was 80.2%. Although the combined application of atailing,oligochitsan and chemical fungicide dimethomorph was less effective than that of protective fungicide mancozeb combined with dimethomorph(94.4%),it reduced the times of chemical agent mancozeb,which could be used as a reference for the reduction control of chemical fungicides in grape downy mildew.
