Abstract

Apple quality and life are significantly deteriorated by Botrytis cinerea, a notorious post-harvest pathogen of apple. To screen environmentally friendly agents against chemical fungicides, this work examines in vitro and in vivo the biocontrol activity potential of 12 Bacillus strains against B. cinerea. The strain B12 was found to be the most efficient according to inhibition assays since it exhibited a high antagonistic effect on PDA plates, even though it was able to prevent the development of mold on apple surfaces. These findings indicate that Bacillus B12 can be an alternative and sustainable strategy for the control of apple mold. To identify robust biocontrol agents. This B12 strain of Bacillus might be a safe and environmentally friendly alternative to the postharvest treatment of apples. The results of the survey underscore the importance of considering microbial competition tactics in sustainable agricultural and storage management.
