The Kahnawake Environmental Protection Office (KEPO) is starting their treatment of several ash trees to protect against the Emerald Ash Borer. Work is expected to continue for two days.

It’s the start of the second annual treatment against the invasive beetle, originally from Asia. For years, the beetles have run rampant across Canada since being discovered in Ontario in 2002.

Montreal has tallied a whopping 30,000 infested ash trees which had to be cut down. The Eastern Door reported last year that the rate of infestation could see the species wiped out within 15 years.

KEPO has employed the help of arborist company Services d’Arbres Primeau to inject approximately 46 trees with an insecticide called TreeAzin.

“It’s made primarily of seed extracts of the neem tree,” says Patrick Ragaz, General Manager of Field Science at KEPO, “which has been used as an insecticide for centuries.”

This round of treatment will only include trees on common land. Trees on private property will need to be assessed for the state of infestation before being treated. Ragaz says KEPO can assist Kahnawákeró:non to find assessment and treatment services.

How to know if an ash tree is infested? Leaves of infested trees often thin and turn yellow, D-shaped holes develop in the bark, which will begin to recede, along with the canopy.
