Crown Gall

Crown Gall causes large abnormal growths at the base of the infected plant or the top of one or more tubers as shown in the adjacent picture. Notice the stretch marks on the skin. The plants are stunted and the shoots spindly. Since there is no effective treatment, infected plants and tubers should be destroyed.

The picture on the right shows the same tuber as above but from a different view.

Crown galls can appear on the body of a tuber as well as on the neck close to the stem of the plant.
