Key practice: Control weeds early through a combination of pre-seed weed control and one in-crop application before the four-leaf stage. Key research: Harker, K. Neil, Agriculture and Agri-Food Canada (AAFC), et al. “Field-Scale Time of Weed Removal in Canola.” Weed Technology (2008). Harker, K.

Canola growers across the Prairies fund many research projects with their levy payments to Saskatchewan Canola Development Commission, Alberta Canola Producers Commission and Manitoba Canola Growers Association. Many of those projects are funded through the joint Canola Agronomic Research Program (CARP) – an arrangement that has been ongoing for almost 30 years. Other projects are funded through arrangements with other organizations listed in these summaries.
Here are short descriptions of and updates on all ongoing projects directly funded by provincial canola grower organizations.
Key practice: Use seed treatments and early in-crop treatments, if scouting deems them necessary, to protect young plants from flea beetles. Key research: Hallett, Rebecca, University of Guelph. “Assessing the Impact of Swede Midge on Canola Production in the Prairies & Ontario.” Canola Agronomic Research Program (CARP 2005-14). Olfert, Owen and Elliott, Bob, Agriculture and... Read More
Key practice: Follow insect thresholds to manage input costs against potential yield response. Conserve and protect natural enemies and beneficial insects by using economic thresholds to determine the need and timing for insecticidal controls. Key research: Bracken, G.K. and Bucher, G.E. “An Estimate of the Relation Between Density of Bertha Armyworm and Yield Loss on... Read More
Key practice: Use soil tests, ideally taken at consistent locations (GPS helps), and base rate decisions on soil test recommendations. Key research: S.A. Brandt, Agriculture and Agri-Food Canada (AAFC), et al.“Seeding rate, fertilizer level and disease management effects on hybrid versus open pollinated canola (Brassica napus L.)” Canadian Journal of Plant Science, 2007.
