Thousand cankers disease (TCD) is a disease complex that threatens millions of black walnut trees (Juglans nigra) in forests and urban areas in the United States. The disease is the result of the combined activity of a fungus (Geosmithia morbida) and the walnut twig beetle (Pityophthorus juglandis).
