Emerald Ash Borer

No question - it’s very distressing to see our natural resources damaged by disease and insect infestations. With the latest problem, Emerald Ash Borer (EAB), the key to any control is to properly identify symptoms to determine the correct treatment. What is sometimes thought to be EAB can actually be other pests, winter stress or other problems. Get a knowledgeable arborist to diagnose any tree infestation/disease problem.

Signs and symptoms of EAB:

• Yellowing of the leaves
• Dieback of the top half of the tree
• Sudden large dead branches
• Separation of bark from the wood
• Galleries under the bark
• Borer holes in the shape of a D 3.5-4.5mm wide
• Leaf damage
• Water sprouts (suckers or epicormic shoots)
• Heavy seed production

Fortunately, the treatment is very friendly to the environment, available under an emergency registration, however it is fairly expensive. It involves an injection that can be done into the tree – no spraying – and is very effective done prior to or early in the EAB life cycle.

If these symptoms are detected, please contact us for assistance.
