Thousand Cankers Disease in North Carolina

Sadly, thousand cankers disease has been confirmed in the Great Smoky Mountains National Park in Haywood County.  This disease has been present in Tennessee since 2010 so it was only a matter of time.  This disease is caused by a fungus carried by walnut twig beetles.  It is native to the southwest US and Mexico where it feeds on a different walnut species. Infected trees die in just a few years.  You can read more on the NCFS alert. There has been a quarantine on the movement of walnut into North Carolina from infested areas. Now there is an additional interior quarantine limiting movement of walnut wood out of Haywood Co. I will post more later on the biology and damage of this disease.
