Winnipeg, MB – The City of Winnipeg’s Elm Bark Beetle Control Program will begin Monday, September 13, 2021, weather permitting.
The program intends to reduce the spread of Dutch Elm Disease (DED) by controlling the beetles that carry the disease.
It will begin in Insect Management Areas 19 (Maple Grove Park, Normand Park, River Park South, St. Vital Centre, Vista), 20 (St. Vital Perimeter South), 21 (La Barriere, Parc La Salle, Perrault, Richmond Lakes, St. Norbert, Trappistes, Turnbull Drive) and 31 (Central River Heights, J.B. Mitchell, Mathers, Sir John Franklin, South River Heights).
With below-normal precipitation occurring this year and the last few years, the City’s elm population is at a higher risk of succumbing to DED and control of the beetle will help to reduce the spread of the disease.
Weekly public service announcements will be issued on Fridays throughout the program indicating which Insect Management Areas will be treated the following week.
Treatment will occur between the hours of 5 a.m. and 5 p.m., weather permitting.
Treatment will be conducted using Pyrate 480 EC® (chlorpyrifos), a chemical product sprayed directly onto the lower 50 centimetres of the tree trunk. This product has 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. This includes a new recommendation for 2021 that application should not occur when temperatures are above 15C.
