Aphids in Canola

Aphids in Canola

What I believe to be Cabbage Aphids have been found in area canola fields, mostly around edges.  If the aphids build in numbers they can reduce canola yields significantly enough to justify an insecticide treatment. Pyrethroids to my knowledge are still the only insecticide chemistry we have labeled for canola: Warrior, Tundra, DeClare, etc.  You might check your fields.  See picture.
