A Temporary Solution
The chemical emamectin benzoate has been proven to be the most lethal pesticide to Emerald Ash Borer larvae, killing close to 100%. The only problem is that this specific chemical can only be administered via systemic injection. Because of it's effectiveness, the City of Lincoln Nebraska has opted to use emamectin benzoate injections but only as a temporary solution. When ash trees die, they are particularly brittle and prone to breaking, making them a hazard to the public. The city does not have the resources to remove all ash trees this year before they begin to weaken, so it has opted to temporarily delay death using systemic injections. City officials aren't worried about the damage caused by drilling and injecting because they only need a temporary solution.
Non-Invasive Root-Zone Soil Injections
Although Treatments with Root-Zone Soil Injections require annual application, they are the best long-term solution for those who intend to save their ash trees instead of just simply delaying their death. The injections in this method are non-invasive to the tree and do not injure the it during application like trunk-injections.

A newly developed treatment known as DINOTEFURAN, was developed specifically to better combat Emerald Ash Borer. It is a chemical that is similar in structure and mode-of-action to nicotine. It is toxic to EAB larvae under the bark & also adults that try to ingest ash tree leaves. Before dinotefuran was available, the pesticide of choice was called imidacloropid. The newer chemical is now much more water soluble, allowing it to move throughout the tree with much more ease.
Don't wait to treat until symptoms appear

Research has shown that by the time symptoms are visible, canopy loss increases at an exponential rate.
If you realize the value of your ash tree, it is essential to take action now. Early Spring is the most effective time to apply a treatment but late-summer to mid-fall applications will help your ash survive until you can begin your annual applications in the spring.
