Updated & Available Now!

Just in time for Spring, the 2019 edition of Insecticide Options for Protecting Ash Trees from Emerald Ash Borer is now available. Take a look at it here.

With timely, reliable information aimed at homeowners, tree care specialists and arborists, this bulletin is a must-read for anyone concerned about their ash trees and/or wanting information on how to manage and protect them, where currently infested with EAB, or located close to an infested region. The most destructive non-native wood boring pest to date, EAB has killed millions of ash trees in North America since its discovery in Michigan and Ontario in 2002.

With timely, reliable information aimed at homeowners, tree care specialists and arborists, this bulletin is a must-read for anyone concerned about their ash trees and/or wanting information on how to manage and protect them, whether infested with emerald ash borer (EAB) or not. The most destructive non-native wood boring pest to date, EAB has killed millions of ash trees in North America since its discovery in Michigan and Ontario in 2002.

 

SO WHAT'S NEW?

Cliff Sadof, Purdue University entomologist and co-author of this bulletin, notes that “EAB’s march through our country mobilized groups of concerned entomologists to find ways to keep ash trees alive.”

Sadof outlined the management and control revisions he and the other entomologists who authored this bulletin focused on:

  • how to use insecticides to effectively and consistently protect even the largest of ash trees from EAB,
  • why irrigation is necessary during drought to assure uptake of protective chemicals happens in the ash trees,
  • how an injections of the insecticide emamectin benzoate can provide up to 3 years of control,
  • when soil or trunk applied insecticides are viable alternatives, and
  • when a tree is too heavily damaged to be saved.

At this writing, there are now 35 US states and five Canadian provinces infested with EAB. Those living in states and provinces without EAB finds are starting to realize this pest may be heading toward their ash trees, as well.

 

WANT MORE INFORMATION?

Finding information about EAB management and control options is EASY:

  1. Go to the Emerald Ash Borer Information Network website for all things EAB.
  2. Find the “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer” bulletin on the home page, or go to the EAB Infested Trees page for additional information on management and control of EAB.
  3. Watch presentations by experts in the field of EAB management and control on the Emerald Ash Borer University webpage.
