What's New in EAB?


Emamectin Benzoate Pesticide Now Registered for Use
in Treating Ash Trees for Emerald Ash Borer (EAB)

**states seeking registration for this new management strategy**

Emamectin benzoate:

* Is the name of a new insecticide that can be used to protect valuable landscape ash trees from EAB in Michigan.

* A special 24(c) registration request for this product was approved by the Michigan Department of Agriculture on March 27, 2008.

* It represents a new tool for protecting valuable landscape ash trees from emerald ash borer.

* The product will be sold as Tree-├Ąge™ (pronounced "triage") and should be available for use this spring.

* Emamectin benzoate has not previously been used to protect ornamental trees. A similar product has been used in salmon farming and in California for some fruit and vegetable crops. A related product is used in veterinary medicine.

* It can be purchased and applied only by trained, certified arborists and landscapers.

* The product is applied as a trunk injection at the base of an ash tree. It is not sprayed on the tree nor applied to the soil.

* Like any systemic insecticide, this product must be transported through the trunk and into the canopy. Therefore, it will usually be more effective in a tree that is reasonably healthy than in a tree that has already been severely injured by EAB larvae.
