Potato wart or potato canker – Synchytrium endobioticum

Potato wart disease is caused by a soil-borne fungus, Synchytrium endobioticum, that attacks the growing points on the potato plant, such as eyes, buds and stolon tips. The fungus can be dormant in soil for more than 40 years while it waits for the ideal conditions to grow: a cool, wet spring and a nearby potato plant.
