Although not yet detected here, thousand cankers disease (TCD) is a potentially fatal disease of black walnut, caused by the walnut twig beetle (Pityophthorus juglandis) and an associated fungus (Geosmithia morbida). TCD could easily spread to Missouri from the several eastern and western states where TCD is already present. You can help minimize the chances of spreading TCD by following these steps:
- Don't move firewood
- Don't transport walnut for woodworking (including buying walnut wood over the Internet)
- Promptly report dead or dying walnut trees
