Canola is an effective tool for both broadleaf and grass weed control in eastern Washington. In particular, the use of transgenic glyphosate resistant canola varieties facilitates management of Italian ryegrass and cheatgrass, troublesome species in winter and spring wheat rotations. Herbicide stewardship should be considered when deploying any of these technologies – where possible and economically feasible, multiple herbicide modes of action should be deployed in season to reduce selection for glyphosate resistance. Additionally, herbicide carryover can cause canola stand establishment to fail. Detailed records and careful attention to rotation intervals on herbicide labels is essential in canola production.
