Treating ash trees with TreeAzin
By Parkland Tree CarePublished Updated
TreeAzin is one of the products used to help protect suitable ash trees from emerald ash borer. It is a systemic insecticide containing azadirachtin and is applied by injection into the tree. Parkland Tree Care has used it as part of our ash-tree care work.
The first question is whether the tree is a sensible candidate for treatment. Its overall health, branch and trunk structure, growing conditions, and signs of infestation all matter. Treatment costs and the tree's value to the property belong in that discussion too.
A tree with serious structural defects or advanced decline may be better considered for removal. On the other hand, a healthy ash in a useful location may be worth protecting through an ongoing treatment program. An assessment helps separate those situations.
Treatment timing, rates, and repeat applications must follow the current registered product label and the applicator's assessment. A product's plant-derived origin does not remove the need for proper handling and professional application. The label is the reference for how it may be used.
If you're unsure whether you have an ash tree, or whether an existing tree is worth treating, we can help you work through that decision. The aim is to choose a realistic plan for that tree, rather than promise that an injection can save every ash.
