摘　　要：采用菌丝生长抑制法测定了啶酰菌胺、嘧菌酯及氟吗啉等6种杀菌剂对茄子绵疫病菌(Phytophthora parasitica)的室内活性。结果表明,20%氟吗啉可湿性粉剂的抑制效果最好,其次为50%啶酰菌胺水分散粒剂和100 g/L氰霜唑悬浮剂;50%嘧菌酯水分散粒剂随着药量的增加,抑制率增长并不显著,但其EC50不是很高;40%百菌清悬浮剂和722 g/L霜霉威盐酸盐水剂两种药剂对茄子绵疫病菌的防效较低,抑制菌丝生长的效果较弱。The toxicity of 6 fungicides against Phytophthora parasitica was detected by the method of mycelium growth inhibi- tion. The results showed that 20% flumorph WP had the best control effect. The followed fungicides were 50% boscalid WG and 100g/L Cyazofamid SC; Butwith the increase of dosage,the control effect of 50% Azoxystrobin WG did not increase sig- nificantly, however its ECso was low. The control effect of 40% chlorothalonil SC and 722 g/L propamocarb hydrochloride aqueous solution were low, with weak inhibition effect on mycelium growth.
