Emerald Ash Borer
We have 2 ash trees that have been treated throughout the ash borer infestation. Is it necessary to continue treating in 2020?
Jefferson County Kentucky
Have you seen any significant changes in foliage density or color, do the trees look normal? If they look healthy that could be a result of the treatment. What chemical have you used and do you treat them yourself? I'm in contact with UK researchers and KY Dept of Forestry on the status of forest health including EAB. I'll follow up with the information researchers share.
