EMERALD ASH BORER

Emerald ash borer adults are very small, metallic green beetles. Only 3/8 - 1/2 inch long and 1/16 inch wide. This beetle kills ash trees only. The green and black ash trees are preferred. White ash is also killed quickly, but usually only after green and black ash trees have been eliminated. Blue ash seems to display some resistance to the borer by forming callous tissue around EAB galleries; however, they are usually killed eventually. The larvae are hatched in the cracks of the bark. They feed on the phloem (responsible for nutrient transport throughout the tree) and xylem (responsible for take-up of water and nutrients) tissues of the tree. They kill trees within two years.

How can I tell if my tree is infected? There are several signs and symptoms of infestation to watch for in your ash tree. 1)Dying back of the crown. An infested tree will start to show dead branches and thinning through out the canopy, starting at the top. Discoloration will also occur in an infested tree. 2) Epicormic sprouting (cluster of small branches) at the base of the tree or on the trunk its self. 3) Splits in the bark from the presence of larvae galleries. 4) The presence of woodpeckers is also an indication. 5) The D shaped hole from a exiting mature beetle is a clear sign. If you are experiencing any of the fallowing please call immediately. There is an arborist on call 24-hours to handle any questions you might have and to evaluate your trees health if so desire.

What's the deal with firewood? Because of the habitat that firewood creates it's possible to spread the EAB through the transportation and distribution of firewood. The selling of firewood is wide spread and often crosses county and state lines. In short since the EAB does not fly very far we are its taxi.

What can I do? Treatment should be in, my opinion, used as prevention rather than a form of extermination. Meaning, take caution and prepare your tree for attackers. But if it does get infected, removal may be required, but treatment is also possible. Understand that treatments are for the long term and not a quick solution.

What are my options for treatment? There are various types and methods available. Most of which all provide some degree of protection. These products can be applied in different ways depending on the applicators choice, which will also determine which product to be used. Annual treatments of pesticides will be required in order to keep the borer under control. It is best not to continually use the same pesticide for multiple seasons in a row. This is due to the fact that any pest exposed to the same pesticide year after year will develop immunities. Changing the formula is very important.

Will I have to treat my tree every year? Yes and No! There are some pesticides that can provide several years of protection, the downside being the cost. Treating your tree on a yearly basis allows for the homeowner to keep their options open. New research and products are always on the horizon.

Ok! What can Bud's Tree Care do for me? We can start out by offering you a plan for the future. If treatment is what you desire then we have a plan for you. The first step is to evaluate the health of your tree and prime it for its upcoming battle. Introducing your tree to a slow release low nitrogen fertilizer, will ensure its on the right track. You want a hearty healthy tree, not just a tree that grows. The second step is injecting your tree with the pesticide for yours and it's protection. It's not whether it gets attacked, it's when.

Homeowners should stay in tune with what's going on around them. Preparation and education is the key. There is hope, and your trees can be saved. The time for action is now. Don't wait until your tree is suffering. Treat your tree while its healthy, rather than trying to get it back. You will save money in the long run and continue to have a thriving healthy ash tree in the process. As an arborist, and the owner, of Bud's Tree Care; I'm working hard to save as many of our ash trees as possible.

Your Arborist,
