ASH Tree loss

Saving that ASH Tree

One advantage ISA Certified Arborist enjoy is the latest up to date information on tree concerns and treatments. One I'd like to share is the concern on the Emerald Ash Bore attacking Ash trees. There has been controversy on removing infected trees versus using chemical treatment to protect them. Certainly if it is your Ash tree you want it protected and not removed.

So what can be done to protect them but limit chemicals in our environment? February issue of Arborist News p58 addressed the issue stating the current science based on University studies favors several treatments and the EPA has registered those treatments one of which I've discussed before called an imidacloprid drench around the tree trunk.

This is a simple application for the home owner. The tree uptakes the product through the roots systemically - when the larvea bores into the tree it contacts the chemical.

Bayer Tree and Shrub has this chemical but in a very diluted container which can make treatment more expensive than it needs to be. You can purchase imidacloprid in containers with higher amounts of active ingredient saving you as much as 40% in cost.

People often wait until summer or until they see aphids or other insects attacking their trees to apply - the time to apply is in the Fall or right now this Spring.
