EMERALD ASH BORER DISCOVERED IN BLOUNT COUNTY
The USDA has confirmed the presence of Emerald Ash Borer in Blount County, TN. Emerald Ash Borer has also been found in Claiborne, Grainger, Knox, Loudon, and Sevier counties. The invasive insect, first discovered in Detroit, MI in 2002, comes from Asia and only attacks Ash trees. The USDA has quarantined the movement of Ash trees, Ash timber, and firewood from moving outside Blount County lines to try to slow the spread of Emerald Ash Borer.
Homeowners with Ash trees should look for signs of Emerald Ash Borer in their trees. Infested Ash trees will display one or more of the following symptoms:
•Reduced leaf growth in the upper portion of the tree
•Splitting tree bark
•Sprouts growing from the trunk or base of the Ash tree
•D-shaped exit holes may even be seen upon close inspection of the trunk of an infested Ash tree
The metallic-green adult Emerald Ash Borer beetle feeds on the leaves of Ash trees causing little harm to the tree. The larva, however, feeds in the cambium of the tree. This disrupts the movement of water and nutrients, eventually leading to the death of untreated trees.
A tree service or arborist can offer several solutions to protect Ash trees from Emerald Ash Borer. Itâ€™s not always necessary to remove a tree infested with Emerald Ash Borers. Treatments for Emerald Ash Borer include trunk injections, tree spraying, soil drenches, or a combination of treatments.
