Title
Canola cultivar mixtures and rotations do not mitigate the negative impacts of continuous canola

Other claims from this paper (6)
- Intervention effect Rotating herbicide-resistant canola types or mixing two cultivars gave no pest management, yield or seed quality advantage over planting the same cultivar type each year.
- Intervention effect Inserting wheat or field pea and wheat into 3-year canola rotations reduced 2010 root maggot damage by 6% compared with continuous canola.
- Intervention effect The same rotations reduced 2013 blackleg incidence by 53% compared with continuous canola.
- Intervention effect The same rotations reduced 2013 blackleg severity by 54% compared with continuous canola.
- Intervention effect Canola grown only once in 3 years yielded 22% more than continuous canola.
- Recommendation The most important mitigation strategy for sustainable canola production is to rotate canola with other crops.
