文摘内容 [Objective]The paper was to study antifungal activity and control mechanism of Bacillus cereus CGMCC4348 against Botrytis cinerea,and further find new methods against the disease.[Method]By quantitative bioassay,in vitro experiment and pot test,the antagonistic protein was extracted with ammonium sulfate precipitation fractionation to determine the control efficiency.EC50of B.cereus CGMCC4348 was 6.19 mg/L.Average controlling effect of B.cereus CGMCC4348 on B.cinerea was 75.8%,equal to the control group which was treated by 50 mg/L pyrimethanil.Bacillus cereus CGMCC4348 had good inhibitory effect against B.cinerea.[Conclusion]The paper provides scientific basis for green control technology against solanaceous vegetable diseases.
