Rotate canola with cereal, pea and forage crops. Control of multiple herbicide tolerant canola within a canola crop may not be possible. Diversifying a rotation permits use of a wider selection of herbicides. Lengthening the rotation depletes the volunteers from the soil weed seed bank. Scout fields for volunteer canola which are not controlled by herbicide application .
Early detection allows time for control before seed set.
Grow competitive crops. Boost seeding rates, choose competitive varieties, seed early, and place a balanced fertilizer close to the seed. Reduce the loss of seed during canola harvest. Properly adjust the combine so that seed losses are minimized. Higher combining speeds increase seed loss.
