I like my ash tree and am considering treating it. What are my options?

First, determine if your ash tree is worth treating. If your ash tree is in decline and already exhibiting more than 50% canopy loss, then the tree is likely too far gone. Similarly, treatment of small ash trees is not recommended since you must treat your ash tree every 1 to 3 years. You may be able to replace your tree with a higher quality tree for a lower cost than long-term treatment. 

If you decide to treat your tree, hire a tree company that uses a chemical injection. We recommend using emamectin benzoate, a chemical that is injected into the trunks of ash trees by a certified pesticide applicator. Injections are the most effective method of treating the tree and cause the lowest risk to the environment. The soil-applied drench chemical imidacloprid is not recommended, due to water quality implications and its impacts on pollinators.
