Emerald Ash Borer
The Emerald Ash Borer (EAB) rises by the thousands like a Phoenix in the night and splashes brilliant green silverly wings in an incipient plague across the Eastern US forests. This insect, arriving from Asia on ash 'pallet-wood' in Detroit in 2002, has no natural control to its population explosion in America and it has a 100% kill rate or mortality result for ash trees in its vicinity. What this means for you, as a homeowner, is that about 5% of all trees in the yards and forests of West Hartford, CT are ash trees, ..... and they are ALL going to die. This is particularly concerning because ash trees seem to rot and fall apart the fastest of ANY tree once it is dead.
Good News; There is a treatment option that I am comforatble using, due to its low toxicity levels, called Tree-Azin and it is injected into the tree in the morning int he spring and summer and it affects the insect like a hormone, causing the EAB to grow too fast and subsequently die. The time has come to decide whether to treat your trees or take them out.
Bad News: The insect spreads and kills quickly, as evidenced by this photo. The first of these insects was spotted in West Hartford in mid 2013 and look at the effect in just three years of being present in this West Hartford tree. The treatment option of Tree-Azin only has an 83% effectiveness in protecting against Emeral Ash Borer, and it must be applied before 30% foliage loss in order to work. The time is now to identify and treat any ash trees which you want to save, and to also decide based on the cost ratio of treatment or removal, before the tree, like in the photo below, become too weak and rotten to remove by climbing.
Check out this article from late 2013 in American Forests magazine which illustrates the speed of already caused by the insect in Ohio on its slow path east. https://www.americanforests.org/magazine/article/will-we-kiss-our-ash-goodbye/
