Fig. 1. Inhibitory effects of Phoma terrestris extract on spore germination of ginseng
pathogens on PDA media. Four concentrations of the Phoma terrestris extract (0.1, 1,
10 lg/10 lL) were tested for inhibitory activity against spore germination of four
ginseng pathogens (A. panax, B. cinerea, C. panacicola, and C. destructans). Percentage
of spore germination was calculated based on approximately 100 spores counted in
three replicates.
