Molecular Approaches in Natural Resource Conservation and Management Thousand Canker Disease Affecting Black Walnut Trees
The Indiana Department of Natural Resources, Division of Entomology & Plant Pathology, is activating Indiana's Emergency Rule for Thousand Canker Disease (TCD) of Black Walnut, effective August 30, 2010. This fungal disease is spread by a small twig beetle, eventually leading to the death of infected trees. TCD disease, endemic in the Western US, was recently identified in Tennessee.

A Thousand Canker Disease Workshop will be held March 31, 2011 with speakers from the Tennessee Dept. of Ag that are currently dealing with an outbreak, along with forest service scientists, survey specialists and leading TCD researchers. For more information see the Hardwood Tree Improvement and Regneration Center (HTIRC) web site.

For more information view the US Forest Service Pest Alert, Indiana Emergency Rule and Indiana Walnut Council. Things we can do to help prevent this disease: check your black walnut trees for signs of this disease; report any dead or declining walnut trees to 1-1-866-NO-EXOTIC; don't move firewood of any kind as it spreads insects and diseases; and don't move walnut material from a known infested area.
