摘　　要：【目的】筛选出防治甜菜褐斑病(Cercospora beticola Sacc.)效果较好的杀菌剂为该病的有效防治提供理论依据。【方法】选择5种杀菌剂,进行防治甜菜褐斑病的田间小区试验。【结果】筛选出防治效果较好的杀菌剂是福星5 000倍液和氟硅唑.多菌灵(12.5%.27.5%)悬浮剂,防效分别为60.80%和58.37%。与其他杀菌剂有显著性差异。5种杀菌剂防治时应连续喷药,间隔期7 d,连续施药2次。【结论】5种杀菌剂均对甜菜褐斑病有一定的防治效果,防效最高的杀菌剂是福星、氟硅唑.多菌灵,可在生产上推广应用。[Objective]The aim of this study was to screen better fungicides for controlling sugar beet leaf spot.[Method]Selecting several fungicides to carry out experiment of controlling sugar beet leaf spot in the field.[Result]Fuxing 5000 times and Flusilazole·Carbendazim（12.5%·27.5%）are better fungicides,their controlling efficiency exceeded 60.80% and 58.37%.They have significant differences from other fungicides.All fungicides slowly give their pesticide effects,the fungicides should be continually applied every 7 days by twice spraying,the control effect will be increased.[Conclusion]Several fungicides have a preventive effect on the beet leaf spot,antiefficient pharmaceuticals：fuxing and Flusilazole·Carbendazim（12.5%·27.5%） have the highest control effects.They could be applied in production.
