Discovery of Highly Invasive EAB in Oregon

Emerald Ash borer (EAB) has recently been discovered in the state of Oregon. Arborjet | Ecologel, a leader in plant health, offers treatment options to help mitigate the spread of EAB, and provides educational opportunities for municipalities and communities to learn about the risks and treatment options to protect and preserve urban tree canopy. Saving mature trees helps to reduce CO2 production, energy costs, and stormwater runoff while also maintaining property values.

“There are many treatment options available for EAB. However, not all chemicals deliver the same results. EAB has been highly researched since its initial detection in 2002. There are over 16 years of research and publications available about treatment and management strategies. Oregon is fortunate in this regard, as we are not starting from scratch. Now is a great time for everyone to familiarize themselves with the pest and the options available,” said Korey Lofy, Rocky Mountain Regional Technical Manager.

Emerald Ash Borer is a bright metallic green beetle originally found in eastern Asia. The tiny beetle feeds and breeds exclusively on ash trees.The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree’s ability to transport water and nutrients. As of July 2022, EAB is now found in 36 states, and the Canadian provinces of Ontario, Quebec, New Brunswick, Nova Scotia, and Manitoba. Since its discovery, it has killed hundreds of millions of ash trees in North America, and is believed to be the most destructive forest pest in North America.

Signs and symptoms of EAB infested ash trees include:

● Thinning canopy
● Bark splits on limbs in upper canopy
● Epicormic sprouts
● Woodpecker activity
● Small D shaped exit holes
● Serpentine galleries beneath the bark

Five years ago, Arborjet launched a company-wide initiative called “Saving America’s Iconic Trees,” to ensure the health and longevity of the country’s trees. The campaign targets America’s most beloved trees, offering complimentary treatment to prevent insects, disease and poor health. Arborjet has donated high-profile treatments and hosted educational events across the country. They invite homeowners, state, city, town and municipal leaders to nominate iconic trees in their communities for potential recognition and treatment.
