- Abstract
[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. EC50 of 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.
