Great article for consumers with an easy to understand explanation from a landscape company….”You should really consider treating your ash tree now since it is not a matter of if but when your ash tree will be affected. There are a couple of systems currently on the market, one of which actually drills a hole in the tree and then needs to be plugged which causes more damage to the tree and unsightly blemishes especially since you will need to continue to treat the ash trees to remain effective against the EAB. Our system is known as the ArborSystems Direct-Inject and is like a flu shot for a tree. It causes almost no noticeable hole, requires no drilling or plug and places the chemical where the EAB does the damage in the cambial zone under the bark. You may be wondering if your ash is worth treating; our chemical is highly effective with a nearly 90% effective rate and can treat a tree that is at least 50% alive. Another plus to our product is that we only need to treat every two years instead of once a year.” For more information, click here.
