Tree-age gets OK to expand label for invasive pests


WOBURN, Mass. — Many states now have a new tool in their pest management arsenal; recently Arborjet announced that Tree-age insecticide received expanded label approval from the EPA to control several invasive species such as western pine beetle, mountain pine beetle and other associated engraver beetles.

Arborists, landscapers and city officials in cities like Milwaukee and Chicago have used Tree-age to treat tens of thousands of trees to protect their urban forests against the invasive pest known as emerald ash borer.


By injecting Tree-age directly into the tree’s vascular system, it not only provides protection quickly, but it is also highly effective in treating insects that feed under the bark. Arborjet trunk injection also seals the applied insecticide in the tree, thus limiting exposure of the chemical to the environment.

Tree-age is applied through the Arborjet injection system where the formulation is sealed inside the tree, and unlike many other treatments, Tree-age provides up to two years of control for insects like emerald ash borer and mountain pine beetle.


A partial list of the insect species covered by the new labeling includes: engraver beetle, pine cone seed bug, pine cone worm, red palm mite, red palm weevil, western pine beetle tussock moth, leafminer and the eucalyptus borer.
