摘　　要：[目的]探讨噻呋酰胺对花生白娟病的田间控制效果。[方法]以50％福美双可湿性粉剂和25％粉锈灵可湿性粉剂为对照药剂，采用小区试验研究240g／L噻呋酰胺悬浮剂不同时期喷施对花生白娟病的防治效果及对花生的增产效果。[结果]在花生开花期、结英初期2次分剐用240g／L噻呋酰胺悬浮剂450ml／hm^2对水喷雾，对花生白娟病的防治效果为49．90％～69．80％，初期效果与常规对照25％粉锈灵1500g／hm^2相当，而中后期效果则好于常规对照，同时能够提高花生产量，增幅为25．41％，优于两常规对照。[结论]240g／L噻呋酰胺悬浮剂既能有效防治花生白娟病又能提高花生产量，可望用于实际生产。[ Objective ] The field control effect of 240 g/L Thifluzamide suspension concentrate against peanut southern blight was discussed. [ Method] Taking 50% Thiram wettable powder and 25% Triadimefon wettable powder as control agents, control effect on peanut southern blight and yield-increasing effect of 240 g/L Thifluzamide suspension concentrate were studied through plot test. [ Result] After the 240 g/L Thifluzamide suspension concentrate at 450 ml/hm^2 was sprayed at flowering stage and pod-setting initial stage, respectively, its control effect against peanut southern blight was 49.90% - 69.80%, among them control effect at the initial stage was close to that of conventional agent 25% Triadimefon wettable powder 1 500 g/hm^2, and control effect at middle and late stages were better than that of conventional agent. Mean- while, 240 g/L Thifluzamide suspension concentrate could improve the yield of peanut, and the improved range was 25.41% , which was bet- ter than two conventional agents. [ Conclusion] The 240 g/L Thifluzamide suspension concentrate can effectively control peanut southern blight and improve peanut yield, so it can be used in produce.
