SPRINGFIELD, Mo.– Emerald Ash Borer is an insect pest of ash trees and has now been identified in Greene County and counties to the east and north. This insect has the potential to destroy all of our area ash trees so homeowners and property owners should be on alert if they have ash trees.
The first and most important thing people should do is do determine if they actually have an ash tree; they are easy to misidentify. Ash tree leaves are compound, but so are other tree species.
One identifying factor is that ash tree buds and branches are opposite
If you do have a high value ash tree, there are some insecticidal treatments than can be used; these must be used on a regular basis; if the DBH is less than 20 inches you can treat yourself, if larger contact a certified arborist
Monitor for die back in the upper canopy of the tree; look for d-shaped exit holes
If they are doing poorly or showing signs of distress it might be best to remove them
Dispose of any wood from ash trees locally; don’t transport to another site
Call your local extension office if you need held identifying an ash tree or have questions
