Once a very destructive disease, blackleg of cole crops has become less important with the introduction of effective control measures. The fungus affects most cole crops, especially cabbage, Brussels sprouts, kohlrabi, radish, rutabaga, and white mustard. Black mustard, broccoli, cauliflower, kale, turnip, and wild radish are moderately susceptible. Mildly susceptible plants include Chinese mustard, cress, rutabaga, and many turnips. This fact sheet presents this disease’s life cycle and offers effective means of control.
