For the selected endophytes, MICs of the EtOAc extracts against the ginseng pathogens were determined by the modified agar diffusion method (Vinale et al., 2006). Ginseng pathogen plugs (0.5 cm diameter) were placed in the middle of petri dishes with a 6 cm diameter containing 10 mL of PDA. Two layers of sterile Whatman filter paper discs with a 0.6 cm diameter containing EtOAc extracts of endophytic fungi (100 lg/10 lL) at concentrations of 0.1, 1, 10 or 100 lg/10 lL and 10 lL controls of acetone:water (9:1, v/v) were then placed on the top of each plug. The plates were subsequently incubated at 25 C for 5–7 days, during which time the colony diameter was measured daily. All experiments were replicated twice with three biological replications.
