A beetle which transmits a walnut tree killing disease has been discovered in East Tennessee.
Friday, the Tennessee Department of Agriculture 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, meaning citizens can move walnut tree products and hardwood firewood within the county, 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. The Tennessee Department of Agriculture Division of Forestry estimates that 1.38 million black walnut trees in Tennessee’s urban areas are potentially at risk from TCD.
The risk represents an estimated value loss of $1.37 billion.
