NASHVILLE – The Tennessee Department of Agriculture today announced the discovery of a walnut tree killing disease, Thousand Cankers Disease (TCD), in Morgan and Rhea Counties. Walnut Twig Beetles, which transmit the disease causing fungus and the disease itself, have been found in both counties. The counties are now under quarantine. Citizens in these counties cannot move walnut tree products and hardwood firewood outside the quarantined counties.
Bledsoe, Cumberland, Fentress, Hamilton, and Meigs Counties are now considered buffer regulated counties because they are adjacent to a quarantined county. Polk and Sequatchie Counties are being placed in the buffer regulated category because of the finding of Walnut Twig Beetles in those counties. Bradley County is also being placed in the buffer regulated category because it is surrounded on the Tennessee side by other buffer regulated counties. Citizens in buffer counties can move walnut tree products and hardwood firewood within buffer counties, but not outside. Product can also be moved into a quarantine county, but not taken back out.
“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.”
