What is the current status of Emerald Ash Borer in PA?
Emerald Ash Borer(EAB) has been confirmed in 4 more counties the closest being Union, and Centre. The Union County site is very close to the Lycoming County border, in Gregg Township. Due to this new discovery the western 2/3 of the state is in a quarantine area. No ash wood products, or any hardwood firewood can be moved out of the quarantine area. This is a serious threat to all Ash species. The mortality rate of unprotected trees infested with pest is over 99%. Non infested trees can be chemically treated to protect them from EAB. The method of treatment is done by trunk injections or soil drenches of pesticides labeled for control of EAB. If you have specimen Ash trees you want to protect, start treatment now. The success rate drops significantly if the tree is infested. If you suspect an infestation of EAB, have the trees checked by a professional arborist or forester.
