🚨 Bertha Armyworm Alert
Bertha armyworm outbreaks are being reported in localized areas of Alberta. Daily scouting is important, as larvae can move between fields and densities can change quickly.
🌱 While canola is most commonly affected, also monitor peas, mustard, flax, quinoa, h**p, alfalfa and potatoes.
More than 15,000 acres of canola and peas have been sprayed in Vulcan County, with additional above-threshold fields reported in Special Areas 4 and the Municipality of Taber.
Know your field—scout early and often!
