Fall Oak Wilt Treatment

Oak Wilt is an especially insidious disease that is easily transmitted and can kill a tree in a single growing season. It affects mostly Live Oak and Red Oak trees. Caused by the spores of a fungus, it is carried from tree to tree by small beetles that feed on tree bark. It can also be introduced to a healthy tree by using unsterilized tools that were previously used on an infected tree. A rapid yellowing of the outer leaves near the top in mid-late spring is an indicator of this disease. The yellowing will spread throughout the entire canopy, with the tree quickly dropping its leaves. Diagnosis by a certified arborist or tree pathologist is critical, as successful treatment depends on early diagnosis of all affected trees within an area. It does little good to treat only one tree.

Because Oak Wilt is so opportunistic, Preservation Tree Services will not prune Live Oak or Red Oak trees when beetle activity is highest, usually from late February until early June. At other times of the year, someone using extreme caution should do any pruning of these trees. A good arborist will prune with as little damage as possible. The spread of Oak Wilt disease is minimized by the pruning technician using a special mixture to seal wounds, and by sterilizing his tools with alcohol before moving between trees.

With the night temperatures dropping right now as we head into fall, it’s a good time for us to start preventative treatments for oak wilt disease. We use a specialized injection treatment that has proven to be the most effective and environmentally responsible method for treating and preventing oak wilt. Don’t wait until spring to see symptoms of oak wilt disease; prevention is always the best approach!

If you think your Live Oak or Red Oak trees may be infected with Oak Wilt, please do not hesitate to contact one of our certified arborists for a diagnosis. We can be reached at (214) 528-2266, or via email at [email protected].
