Wart disease of potato

Only the below ground symptoms are apparent. Rough, warty growths at the base of the stems. Eyes develop into warty, cauliflower-like outgrowths that can be cut more easily than the tuber. Growths are white below ground, green when exposed to light, and darken with age. The warts range from the size of a pea to large masses that cover the entire tuber.
