The effect of winter annual weed control with 2, 4-D Amine, and Pre-Seeding Burn-off with Glyphosate/Dicamba on subsequent canola production

Researcher: Dr. Ken Kirkland, Agriculture and Agri-Food Canada, Scott, SK

Project Code: CARP 9235

Final Report: December 1994

Summary: Researchers at the Agriculture and Agri-Food Canada Scott Research Station conducted a three-year study from 1992 to 1994 to determine if late fall or early spring applications of 2,4-D amine had an effect on subsequent canola emergence and growth. Overall, the research results showed that producers could safely apply 2,4-D in the fall prior to seeding canola the following spring. Canola producers involved in zero tillage or direct seeding systems, and those practicing conventional tillage who wish to avoid a late fall tillage could benefit from the October application of 2,4-D for winter annual weed management.
