Walnut tree infected with Thousand Cankers Disease
NASHVILLE – The Tennessee Department of Agriculture today announced the discovery of Walnut Twig Beetles, which transmit Thousand Cankers Disease (TCD), a walnut tree killing disease in Marion County. The county is now buffer regulated. Citizens in buffer counties can move walnut tree products and hardwood firewood within buffer counties, but not outside. Products can also be moved into a quarantine county, but not taken back out.
In addition to Marion County, Bledsoe, Campbell, Claiborne, Cocke, Cumberland, Fentress, Grainger, Greene, Hamblen, Hamilton, McMinn, Meigs, Monroe, Polk, Roane, Scott, and Sequatchie are also considered buffer regulated counties because the Walnut Twig Beetle was found or they are adjacent to a quarantined county. Bradley County is also in the buffer regulated category because it is surrounded by other buffer regulated counties.
“We will continue to survey for the Walnut Twig Beetle and Thousand Cankers Disease to help slow the spread of the disease,” said TDA Plant Certification administrator Gray Haun. “We are working with stakeholders to help educate citizens on the symptoms of TCD and how they can help.”
