Protection of Tobacco Plants from Bacterial Wilt with Avirulent Bacteriocin-Producing Strains of Pseudomonas solanacearum

비병원성 Bacteriocin 생성 Pseudomonas solanacearum을 이용한 담배 세균성마름병 방제

Control effect of an avirulent bacterlocin-producing strain(ABPS) Y6l-1 of Pseudomonas solanacearum on bacterial wilt was 58.8 % when the bacterial suspension had poured onto the rhizosphere soil of tobacco cultivar NC82 on one day before transplanting to the field and of hilling time. Until eight weeks after inoculation, survival of the strain on rhizoplane and in stem of the plants inoculated was better than that of other four strains tested. It suggested that survival of the ABPS in and on the plants should be supported for the sufficient protection.
