Cutworms, flea beetles of concern in Manitoba
May 25, 2016 - Cutworms and flea beetles on canola are the insects of greatest concern currentlyin Manitoba. According to provincial entomologist John Gavloski, seed treatments should still be effective against flea beetles in most canola fields, although scouting for feeding damage is encouraged, especially in the earlier seeded fields where seed treatments may soon start losing effectiveness.
Meanwhile, cutworm levels are quite variable, hard to find in some fields, more noticeable in others. So scout for potential cutworm feeding on emerging plants and dig for the larvae if you find an area that is showing signs of cutworm feeding.
