Treatment will occur between the hours of 6:30 a.m. and 5:30 p.m. Monday to Friday until late July, weather permitting. Crews will use TreeAzin® (azadirachtin) or IMA-jet® (imidacloprid), which have been approved for use in Canada by Health Canada’s Pest Management Regulatory Agency and will be used in accordance with federally approved label directions by licensed pesticide applicators.
While only health ash trees are being treated, it is anticipated that all of Winnipeg’s Ash trees will eventually succumb to EAB over the next 10-20 years. These treatments aim to temporarily preserve the healthy portion of our urban canopy to allow the City to proactively manage tree removals.
“It's important to be proactive in slowing the mortality of our ash trees,” said Kerienne La France, Supervisor of Urban Forestry Technical Services. “We are selecting the best of the ash trees on public property for these injections, so we get the best value out of the treatments.”
For the third straight year, the City will inject ash trees with insecticides capable of killing Emerald Ash Borer larvae inside the trunks.
“Winnipeg’s character and identity are largely shaped by our urban forest and the detection of this new invasive species has placed our urban forest under even greater threat,” La France said.
