Emerald Ash Borer Treatment
Emerald Ash Borer (EAB) is a tree insect that is sweeping the Milwaukee Metro area of SE Wisconsin and killing thousands of Ash Trees. It’s a relatively new pest in the Midwest and is now found throughout the Milwaukee metro area including Waukesha County, Ozaukee County and Washington County. It will severely injure and kill all Ash tree species if not treated by a professional Arborist.
How to Identify an Ash Tree
There are many trees that fall under the “Ash Tree” species. There are three traits Ash trees have that can help you quickly identify if you have one:
- Opposite branching – this means that your twigs sprout off the main branch at the same point on both sides, directly across from each other.
- Compound leaves – each leave stem has separate bunches of 5-11 leaflets.
- Smooth edge leaves – there are no lobes on the leaves like seen on a maple or oak tree.
Emerald Ash Borer Symptoms
- Dieback of leaves beginning in the upper one-third of the canopy and progressing downward over time.
- Vertical splits in the trees bark.
- D-shaped exit holes in bark.
- S-shaped channels under bark
- Numerous water sprouts from the lower trunk.
How to control EAB?
Along with other tree care services, chemical treatments are needed to stop this pest in it’s tracks. One treatment from M&M Tree Care is good for two years! Our certified Arborists have extensive experience identifying and treating EAB. The active chemical we use is called Emamectin Benzoate. Common trade names are Tree-age and Arbormectin. Treatment is a direct injection into the trunk of the tree. An organic root stimulant will improve the health of the Ash root system as well and should be applied during the off year of the two year trunk treatment.
