摘　　要：[目的]筛选对葡萄霜霉病防效最佳的生物药剂。[方法]选择0.3%丁子香酚、0.3%苦参碱、10%多抗霉素等9种生物药剂开展葡萄霜霉病菌的室内毒力测定。[结果]供试药剂对孢子囊萌发抑制效果最好的是0.3%苦参碱,其EC_(50)值和EC_(90)值分别为2.1834和0.5464 mg/L,其次是0.3%丁子香酚;而在葡萄霜霉病预防和治疗的毒力测定中,预防和治疗效果最好的药剂是0.3%丁子香酚,其次药剂效果较好的为0.3%苦参碱。[结论]0.3%丁子香酚和0.3%苦参碱可作为生物药剂防治葡萄霜霉病。[Objective]To select the best biological fungicides for controlling grape downy mildew.[Method]The indoor toxicity determination of grape downy mildew were used to compare 9 kinds of biological fungicides,including 0.3%Eugenol,0.3%Matrine and 10%Polyoxin.[Result]0.3%matrine had the best inhibition effect on sporangium germination,its EC_(50) and EC_(90) values were 2.1834 and 0.5464 mg/L respectively,followed by 0.3%Eugenol.In the toxicity test of grape downy mildew prevention and treatment,0.3%Eugenol had the best prevention and treatment effect,followed by 0.3%Matrine.[Conclusion]The 0.3%Eugenol and 0.3%Matrine can be used as biological agents to control grape downy mildew.
