| What is Potato Wart? |
|
Potato wart is a soil borne disease of potatoes caused by a single celled fungus, Synchitirum endobioticum. Disease symptoms usually appear only on tubers and stolons (underground stems). Above ground symptoms are usually not obvious, although a reduction in plant vigor may occur.

| Where? |
|
This disease is present in Asia, Europe, Africa, South America, and New Zealand. In North America, the disease has been reported in Newfoundland and Prince Edward Island, Canada and in Maryland, Pennslyvania, and West Virginia. The infestations in Maryland, Pennsylvania and West Virginia are all considered officially eradicated by the USDA. Canada has adopted containment measures and long-term management plan to prevent further spread of the disease and to minimize impacts on trade.
