Abstract:
A rhizobacteria strain named RS-3 exhibited inhibitory activity against all five Panax ginseng pathogens was isolated from the root of P. ginseng. This strain was identified as Bacillus amyloliquefaciens based on its morphological character and 16S rDNA sequence. Antagonistic activity experiments indicated that the strain could strongly suppress Botrytis cinerea Pers with an inhibitory rate of 54.4%, suggesting the potentialities of biocontrol agent against diseases that frequently happen on ginseng.
