City continues to manage Dutch Elm Disease and Emerald Ash Borer threat

The City of Fredericton remains busy dealing with several threats to the community’s Elm and Ash trees. 

In addition to managing the spread of the disease through removal of diseased Elms, City crews began an inoculation program earlier this year to slow the spread of Dutch Elm Disease on City-owned trees.  The pilot project saw trees greater than 30cm and located primarily in the downtown plat and old Devon inoculated with DutchTrig®, a bio-control vaccine for elms.

DutchTrig® is a biological and organic control agent consisting of spores of the Verticillium fungus that, once injected, activates the elm tree’s natural defense mechanisms.  

Meanwhile, the City is preparing for the arrival of the Emerald Ash Borer Beetle. First detected in North America in 2002 and estimated to cost Canadian municipalities $2 billion in management costs over the next 30 years, the Emerald Ash Borer Beetle is a highly destructive pest that has killed millions of ash trees across the continent. The beetle arrived in Edmundston earlier this year. City crews installed an early warning system early this summer.

“The Emerald Ash Borer Beetle and Dutch Elm Disease are real dangers to our community’s majestic Ash and Elm trees," said Coun. Henri Mallet, Chair of the City of Fredericton Community Services Committee. “City staff are working hard to protect Fredericton from this devastating pest and ask the residents for their cooperation.”

Homeowners are encouraged to closely watch Elm and Ash trees on their property and take steps to properly manage and report any trees that have been infected with Dutch Elm Disease or the Emerald Ash Borer Beetle. Information provided will help City staff manage the pest and assist residents.
