Characterization of a native Bacillus velezensis-like strain for the potential biocontrol of tropical fruit pathogens

•Antagonistic bacteria from mango phyllosphere against C. gloeosporioides.•Most effective antagonist was identified by 16S rDNA as Bacillus velezensis.•B. velezensis TS3B-45 displayed remarkable antifungal activity in vitro & in vivo.•B. velezensis TS3B-45 treatment did not affect quality parameters of mango.•First report of B. velezensis as suitable agent for postharvest conservation.
