Walnut Tree Quarantine In Morgan And Rhea Counties Due To Thousand Cankers Disease

Wednesday, November 06, 2013

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.”

TCD is a progressive disease that may kill a tree within two to three years after initial symptoms are detected. The disease-causing fungus, Geosmithia morbida, is transmitted by the Walnut Twig Beetle, Pityophthorus juglandis. Branches and trunk tissue are killed by multiple infections of the fungus as the beetles carry the fungus from one area to the next.

TDA plant inspectors and foresters will continue to conduct a thorough survey of trees in these areas to assess the extent of the infestation and to see if more areas need to be quarantined. Counties already under quarantine for TCD include Anderson, Blount, Jefferson, Knox, Loudon, Sevier and Union. Adjacent counties to the quarantined areas are also restricted for movement of walnut products and hardwood firewood.

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. There are an estimated 26 million black walnut trees on Tennessee public and private timberland potentially valued as high as $1.47 billion. 

TDA officials urge area residents and visitors to help prevent the spread of TCD:

· Don’t transport firewood, even within Tennessee.  Don’t bring firewood along for camping trips. Buy the wood you need from a local source. Don’t bring wood home with you.

· Don’t buy or move firewood from outside the state.  If someone comes to your door selling firewood, ask them about the source, and don’t buy wood from outside the state. 

· Watch for signs of infestation in your black walnut trees.  If you suspect your black walnut tree could be infested with TCD, visit http://www.tn.gov/agriculture/regulatory/tcd.shtml for an online symptoms checklist and report form or call TDA’s Regulatory Services Division at 800 628-2631

Roy Exum: Al Sharpton’s Wise Remarks

I’ll admit I paid little more than scant attention to the Monday funeral of Michael Brown, the 18-year-old who was shot and killed by police bullets in Ferguson, Mo., after he allegedly was involved in strong-armed robbery. There are too many tawdry details and, in my way of thinking, there is nothing under God’s sun, absolutely nothing, that gives others the right to riot, burn ... (click for more)
