Thousand Cankers Disease
Thousand cankers disease (TCD) is a disease complex native to the western United States and primarily affects black walnut Juglans nigra. This disease is the result of the combined activity of a fungus (Geosmithia morbida) and the walnut twig beetle (Pityophthorus juglandis).
Thousand cankers disease currently threatens millions of black walnut trees in forests and urban areas, an important species with great economic and ecological value throughout its native range. Several quarantines have been established in an attempt to prevent the disease from spreading.
