KINGSFORD -- Its presence has destroyed millions of trees and resulted in quaratines in several counties in Upper Michigan last year.  Now, however, there is a way to fight the emerald ash borer without harming the environment.

It's a daunting task.  Since the infestation was discovered in the U.S. in 2002, millions of trees have been infected by the Asian beetle that burrows under the bark of ash trees and disrupts their vascular systems, often resulting in the death of the tree.

A new tree infusion technology, however, may help turn the tables.  By drilling holes into the tree and inserting coated plugs, specialists can send pesticide into the tree.  Once the holes are drilled and the plugs set, the tree is then hooked up to an I.V. that sends pesticide directly into its vascular system.

It's similar to IVs used on people.

"This is really exciting to realize they're treating the tree like we would treat people with medicine," said Eugene Cudnohufski, a Kingsford homeowner who recently had his ash trees protected by the technology.

What's even better is the pesticide doesn't harm the tree or the environment, though it does stop the emerald ash borer in its tracks.

Tree infusion does have one drawback, however.  It may not work for large areas, like forests.

"It would be extensive to go through a whole forest system," said Tim Dettman, owner of Clean Kill Pest Control.  "It would take probably a lot of people and a lot of equipment to contain it that way."

Clean Kill is the only company in the area that supplies the tree infusion service.  The pesticide is good for ornamental trees and is effective for two years.

Despite the advances in technology to stop this pest, precautions still need to be taken to ensure that larger stands of ash aren't affected.

"Mainly, do not transport fire wood," Dettman said.  "I believe that that's the primary way it's spread."

Also, if you suspect that you've found a tree that has been infected, you should contact your local wildlife authorities.
