摘　　要：为筛选出防治黄瓜霜霉病的最佳药剂,选用13种不同类型的杀菌剂在黄瓜霜霉病发病初期进行喷雾防治。结果表明,供试药剂对黄瓜霜霉病均有一定的防治效果,保护兼治疗剂防治效果较好,复配制剂防效好于单剂;66.5%霜霉威盐酸盐水剂、52.5%噁唑菌酮·霜脲氰水分散粒剂、22.5%啶氧菌酯悬浮剂和35%氰霜唑·烯酰吗啉悬浮剂对黄瓜霜霉病的防治效果较好,防效均达76%以上,其中,35%氰霜唑·烯酰吗啉悬浮剂的防治效果最好,防效可达81.39%。建议在黄瓜霜霉病发病初期选用以上4种药剂进行防治,间隔7~10d用药一次,连续防治2~3次,生产中应轮换交替使用各药剂。To screen suitable fungicides to control cucumber downy mildew, 13 pesticides were introduced to control cucumber downy mildew in the early phase. The results showed that the tested pesticides had certain control effect on downy mildew of cucumber. The control effects of protective and therapeutic were better on cucumber downy mildew, the control effects of mixtures of pesticides were higher than that of single pesticide. The control effects of 66.5% propamocarb hydrochloride, 52.5% famoxadone·cymoxanil, 22.5% picoxystrobin and 35% cyazofamid were better, and the control effect was more than 76%. The control effect of 35% cyazofamid· dimethomorph was the best, which was 81.39%. It suggested that these 4 pesticides should be chosen at the beginning of the disease, control once every 7-10 d for 2-3 consecutive times. Each pesticide should be used alternately in production.
