[QUOTE="lfnh, post: 4849356, member: 23498"] Ash have been taking some big hits from ash yellows, which stresses the upper growth, showing die back similar to EAB infestation. Traditional borers seem to be hammering ash harder the past couple years, esp on these stressed trees. EAB and old time borers have distinct exit holes out the bark. EAB holes are bout 1/8"d and are a distinct D shape. Other borers exit holes are round. D shape hole is positive confirmation. [/QUOTE]
