Night spraying outperforms dawn for weed management

On average, herbicides were most effective when applied in the daytime, and night spraying gave better results than dawn application.
Key practice: Midday herbicide applications are most effective for canola; midnight application for grassy weeds. Project title, Lead researcher: “Night spraying — Pesticide efficacy with night time application (2012-14),” Ken Coles, Farming Smarter Grower organization funder: ACPC Any reduction in herbicide efficacy quickly impacts the return on input investment. With the short Prairie growing season,...

An improved hybrid system for breeding canola Brassica juncea

Key practice: The Ogura cytoplasmic male sterility (CMS) hybrid system, commonly used in B. napus, will position B. juncea breeders to produce more stress tolerant, blackleg resistant and pod shatter resistant high-yielding canola B. juncea hybrid varieties. Project title, Lead researcher: “Improving the Ogura CMS hybrid system and establishing heterotic gene pools for hybrid breeding...

Precise seed-to-seed spacing not necessary for canola

Key Practice: The key step in seed placement is to achieve the overall target population with some aspect of uniform distribution and depth. Precision tools to enhance seed spacing in the row provide little evident economic benefit. Project Title, Lead Researcher: “Seeding rates for precision seeded canola,” 2012-14, Gazali Issah, Western Applied Research Corporation Grower...

Glyphosate-resistant kochia survey

Key practice: Taking action to manage glyphosate-resistant kochia before it is visible in the field is critical to success. Use a rotation of broadleaf control products with good activity on kochia. Project title, Lead researcher: “Glyphosate-resistant kochia (Kochia scoparia L. Schrad.) in Saskatchewan and Manitoba,” 2013-14, Hugh Beckie, Agriculture and Agri-Food Canada (AAFC) Grower organization...

Feasibility of growing winter types of Brassica rapa in Alberta

Key practice: Growers in southern Alberta may want to consider winter B. rapa as a suitable alternative to hybrid spring canola (B. napus), which could be a good fit with other winter crops grown there, especially winter wheat. Project title, Lead researcher: “Evaluation of winter Brassica rapa for cultivation in Alberta,” 2007-11, Habibur Rahman, University...
