Glyphosate-resistant kochia survey

Science Edition 2015—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...

Use seed treatment to minimize early disease

Science Edition 2014—Key practice: A registered seed treatment with multiple fungicide active ingredients can minimize the threat of seed and seedling diseases. Seeding early, shallow and with good seed to soil contact for quick emergence also helps prevent early disease infection. Start field scouting 10 to 14 days after seeding. Key research: Hwang, S.F., Alberta Agriculture and...

Phosphorus is often under-applied

Science Edition 2014—Key practice: In the seed row is the best time and place for the first 15 to 20 lb./ac. of phosphate — which is the amount most likely to produce an economic return in the year of application. However, this rate is not enough to match crop removal, which may lead to phosphorus shortages over...

Protect canola from early insect feeding

Science Edition 2014—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...

Top dress if deficiencies are likely

Science Edition 2014—Key practice: In Western Canada where the growing season is short, the ideal practice is to apply all fertilizer at the time of seeding. However, if shortages are expected or crops are showing deficiencies, soil-applied applications of nitrogen or sulphur fertilizer after emergence will likely provide an economic benefit. Key research: Guy Lafond, Agriculture and...
