Ash borer - effective treatment

Asked June 30, 2014, 10:07 AM EDT

Hi. Is there an effective treatment for ash borer? Does dinotefuran work? Spray on the bark? Saw an article stating that best used with pentrabark. Will that help? Thanks Bob Perry

EAB treatment does work, but has to be preventative. Dinotefuran bark sprays do work and are quite easy to apply. Easier than drilling holes in the trees and pumping Tree-age into the tree. The Tree-age will last longer, but from what I have heard from arborists, it is time consuming to inject. Trunk spraying (especially if you are treating lots of trees) is quicker and easier. Take a look at the links below.
