Fig. 1. Growth and development of Cylindrocarpon destructans on ginseng roots. A: Lesion development by highly (right) and weakly (middle) virulent isolates on 3-year-old roots 2 weeks after inoculation. A wound (1.0 × 0.25 mm in diameter) was created with a sharp pin on the upper inoculation site while the lower inoculation site was unwounded.
