Rusted root rot is one of the most common diseases in Panax ginseng, and Cylindrocarpon destructans main pathogenic fungus. The objective this study was to screen explore extracts biocontrol bacteria isolated from ginseng rhizosphere soil against destructans. Bacterial strains Bacillus amyloliquefaciens YY8 Enterobacteriacea YY115 were found exhibit vitro antifungal activity C. A combination crude protein extract B. ethyl acetate a 6:4 ratio exhibited strongest Measurements electrical conductivity, content, nucleic acid content suspension cultures treated with mixture indicated that disrupted cell membranes rusted mycelia, resulting leakage electrolytes, proteins, acids cells, ultimately inhibiting growth combined suppressed infection roots discs by effectively. obtained two bacterial effectively inhibited P. ginseng. It can provide scientific basis for development new biological control pesticides, reduce use chemical promote sustainable agriculture.
