Verticillium Black-Spot Disease of Radish

Abstract

Verticillium dahliae was found to be the cause of Verticillium black-spot disease of radish (Raphanus sativus L.), which has not been described up to this time. Diseased plants exhibited black discoloration of the xylem of the tap root and inconspicuous yellowing of the lower leaves. Inoculation experiments indicated that the fungus was also pathogenic to turnip, egg-plant, strawberry, tomato and cucumber.
