Was out checking out my fruit and nut trees at the farm this last weekend and noticed the newly emerged leaves wilting on one of my chestnut trees. As soon as I saw the wilted leaves I suspected what the problem was. Borers had attacked the tree. I’ve had it happen before several years ago but that time it was on much smaller trees. The tree this year is at least a three inch caliper tree. Supposedly these beetles only attack trees that are stressed....this chestnut tree was healthy. Now it will likely die. If you look close you can see the frass tubes being pushed out of each hole. These type of bores can be controlled or at least repelled by spraying the trunks early in the spring with bifenthrin insecticide but the timing has to coincide with the egg laying of the adult beetles.
Has anyone else had issues with borers in chestnut trees?
