摘　　要：为了筛选安全、高效的黄瓜霜霉病防治药剂,选择687.5 g/L氟菌·霜霉威(银法利)悬浮剂等9种低毒杀菌剂,以33.5%喹啉铜悬浮剂作对照,进行了田间药效试验.试验结果表明,100 g/L氰霜唑悬浮剂、500 g/L氟啶胺悬浮剂、72%霜脲·锰锌(克露)可湿性粉剂,以及75%百菌清可湿性粉剂、687.5 g/L氟菌·霜霉威(银法利)悬浮剂、722 g/L霜霉威盐酸盐(普力克)水剂6种药剂在试验剂量范围内表现出较好的防治效果,并且对供试作物安全,可作为田间防治黄瓜霜霉病的优选药剂.In order to screen out safe and effective fungicides for controlling cucumber downy mildew,9 fungicides with low toxicity,including 687.5 g/L fluopicolide-propamocarb(Yinfali)suspension concentrate(SC),were selected and the field efficacy test were conducted,by taking 33.5%quinoline copper SC as control treatment.The results showed that the 6 fungicides,100 g/L cyazofamid SC,500 g/L fluazinam SC,72%cymoxanil-mancozeb wettable powder(WP),75%chlorothalonil WP,687.5 g/L fluopicolide-propamocarb SC,722 g/L propamocarb hydrochloride(Pulike)water aqua(AS),showed good control effect in the range of experimental dose,and they were safe to cucumber,thus,the 6 fungicides could be used as the preferred fungicides for controlling cucumber downy mildew in field.
