Verticillium Wilt of Potato Caused by Verticillium nigrescens Pethybridge

Abstract

A potato wilt disease new to Japan was found. Diseased plants became yellow, defoliated and dead rapidly. Verticillium nigrescens Pethybridge was isolated from the plants. Inoculation tests on various plants in a greenhouse proved that the fungus caused disease only on potato, and not on eggplant, tomato, bell pepper, cucumber, melon, adzuki bean and soybean.
