Thousand cankers disease is a fungal disease of walnuts (Juglans
spp.) that is carried from tree to tree by a small bark beetle called the walnut twig beetle (Pityophthorus juglandis
). It has killed countless ornamental black walnut trees in the western U.S. and was found for the first time in the eastern U.S. in 2010. The first recorded incident of thousand cankers disease in North Carolina (Haywood County) was confirmed in late fall, 2012. Please report the location and descriptions of potentially positive trees to 1-800-206-9333
