Verticillium wilt of alfalfa (Medicago sativa L.) caused by V. albo-atrum occurred in Hokkaido in 1980. Diseased plants showed both wilting and yellowing of tops. Vascular bundles were brown, but no external symptoms were observed on roots. Plants with severe damage stunted and sometimes died. This fungus was pathogenic to egg-plant, tomato, cucumber, Japanese radish, and spinach in additon to alfalfa.
