With the discovery of volunteer canola with resistance to several herbicides, farmers need to take resistance problems into consideration when they plan their crop and herbicide rotation. Alberta Agriculture researchers have put together a nine-point strategy to control volunteer canola. Leave volunteers on the soil surface as long as possible. Seeds left on the surface may germinate or be killed by frost. Till immediately before seeding to control volunteer canola.
Tillage plays an important role in weed control.
Rotation of herbicides is important for resistance management. Use non-chemical weed control like silage, green manure and forages in a rotation to control volunteers. Include cereals, peas and forage crops in your rotation. Rotation permits a wider selection of herbicides. Scout fields for herbicide tolerant-volunteer canola.
