Systemic insecticide application can protect an ash tree from EAB; however, it is crucial that you apply the right insecticide at the right time of year and that it be used before the tree is already significantly damaged by EAB. The most effective insecticide typically must be applied by a licensed professional. Cost and practicality are also major factors in evaluating pesticide treatment for particular trees. “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer” is the authoritative publication on this topic, and anyone considering pesticide use should read it.
