ABSTRACT
In this study, endophytic bacteria were isolated from roots of P. ginseng by plate culture method, and as a result, 40 endophytic bacterial strains were isolated, Bacillus spp. and Pseudomonas spp. were predominant. By confront culture method, two antagonistic endophytic bacterial strain, ge15 (Stenotrophomonas maltophilia) and ge25 (Bacillus sp. ) against Cylindrocarpon destructans, Sclerotinia schinseng and Alternaria pana were identified. The inhibition zone of ge15 to them were 5.5, 22.0, 14.8 mm, respectively; and which were 12.7,16.5,9.0 mm for ge25. The Results indicate that endophytic bacteria have biocontrol potential on ginseng pathogens, and which can be used as a bio-control factor on ginseng soilborne diseases control.
