A total 115 isolates of Fusarium species from ginseng roots of `rotted´ and soils collected during 1982∼1985 in Korea, were classified to 11 species. The most dominant of these species were F. solani (55 isolates), F. oxysporum (35 isolates), and F. moniliforme (10 isolates). The other 8 species (15 isolates) were very rarely isolated and previously identified as F. roseum sensu Snyder & Hansen (1945) ; these were F. equiseti, F. avenaceum, F. graminum, F. arthrosporides, F. sambucinum, F. reticulatum, F. semitectum and F. poa. Tested for the ability to infect the roots of ginseng (3yr. old plant) in field condition with the mycelial inoculum, only one isolate of F. solani (34 isolates teated) and one isolate of F. oxysporum (24 isolates tested) were weakly pathogenic to ginseng roots. Any of the isolates (7 isolates tested) of F. moniliforme were not pathogenic to ginseng. However, all the isolates of tested of the species of Phytophthora cactorum, Pythium ultimum and Cylindrocarpon destructans were highly pathogenic to ginseng roots.
