摘　　要：[目的]为了筛选出对元胡霜霉病安全高效的杀菌剂。[方法]采用田间小区试验方法测定了8种杀菌剂在试验设计剂量下对元胡霜霉病的田间防治效果以及对元胡的安全性。[结果]各试验小区的元胡生长正常,无明显影响;70%氟吡菌胺·霜脲氰水分散粒剂、23.4%双炔酰菌胺悬浮剂、722 g/L霜霉威盐酸盐水剂3种药剂对元胡霜霉病表现出较好防效,防治效果分别为83.3%、78.5%和73.6%;100 g/L氰霜唑悬浮剂、80%三乙膦酸铝水分散粒剂和80%烯酰吗啉可湿性粉剂3种生产中常用药剂相对表现不佳,防效分别为43.6%、50.9%和51.3%。[结论]70%氟吡菌胺·霜脲氰水分散粒剂和23.4%双炔酰菌胺悬浮剂对元胡霜霉病的防治效果优于722 g/L霜霉威盐酸盐水剂,在防治元胡霜霉病的过程中可推荐使用。[Aims]This study aims to screen out safe and efficient fungicides against downy mildew of Corydalis turtschaninovii.[Methods]The field plot trial was carried out to determine the field control efficacy of 8 fungicides against downy mildew of C.turtschaninovii and the safety to it with designed dosage.[Results]The eight tested fungicides had no obvious effect on the growth of C.turtschaninovii,and three fungicides showed good control effects on downy mildew.The control efficiency of fluopicolide·cymoxanil 70%WG,mandipropamid 23.4%SC and propamocarb hydrochloride 722 g/LAS were 83.3%,78.5%and 73.6%,respectively.Three frequently used fungicides in the production cyazofamid 100 g/L SC,fosetyl-aluminium 80%WG and dimethomorph 80%WP performed poorly,with control efficiency of 43.6%,50.9%and 51.3%,respectively.[Conclusions]Fluopicolide·cymoxanil 70%WG and mandipropamid 23.4%SC,having better control efficacy than propamocarb hydrochloride 722 g/L AS,is recommended for use in the control of downy mildew of C.turtschaninovii.
