Fig. 1. Biocontrol efficacies of the selected chitinolytic bacteria against ginseng damping-off pathogens. (A) In vitro inhibitory activity of the chitin-degrading bacteria (Serratia plymuthica C-1, Chromobacterium sp. C-61; Ly, Lysobacter enzymogenes C-3) on PDA against damping-off pathogens of ginseng: Rh, Rhizoctonia solani; Py, Pythium ultimum. (B) In pot biocontrol efficacies of the selected chitin degrading bacterial cultures grown in a chitin mimimal medium. Ginseng seedlings with damping-off disease infested soils in plastic pots were treated with bacterial cultures or sterile chitin minimal medium as control.
