Pink Rot
Infected areas appear dark brown to purplish black. The margin of the decay is often limited by a dark line. Infected skin is easily rubbed off.The internal rot usually begins at the stem end and is cream to light brown. The rot has a texture similar to that of a boiled potato. When infected tubers are cut, the flesh turns pink in about 20 minutes and with time turns black.
