摘　　要：[Objective] The study was to provide the theoretical guidance for the control of rice sheath blight using the mixture of endophytic Bacillus megaterium strain B196 and fungicide. [Method] The toxicity of the mixture of endophytic strain B196 and jinggangmycin against Rhizoctonia solani was determined by inhibition rate method,and the effect of the mixture on R. solani was also tested. [Result] The mixture of B196 strain and 5% Jinggangmycin water agent with the mass ratio of 1∶68.47 had synergy effect,co-toxicity coefficient （CTC） was 209,the control effect of 200 μg/ml mixture against R. solani was 75.57% in field,which was 17.68% higher than that of single endogenous bacillus strain B196 treatments. [Conclusion] The mixture of endophytic strain B196 and Jinggangmycin had good control effect against R. solani.[Objective] The study was to provide the theoretical guidance for the control of rice sheath blight using the mixture of endophytic Bacillus megaterium strain B196 and fungicide.
