The Canola Council of Canada (CCC) and Agriculture and Agri-Food Canada (AAFC) will bring together a global network of leading researchers and academics to exchange information and research results at the 2013 International Clubroot Workshop in Edmonton, June 19-22. The workshop will have practical value for anyone, including growers and agronomists across the Prairies…

CCC agronomy specialists have a new project for 2013 — the Ultimate Canola Challenge (UCC). The underlying challenge is to follow all best management practices (BMPs) to see how canola yields when you “do everything right.” Additional treatments — such as boron — will be evaluated to see if they provide an improvement in yield, quality, maturity and return on…

When fields are sulphur deficient, canola that receives only nitrogen fertilizer (front left in photo) can yield less than canola that receives no fertilizer at all (right in photo). Canola plants need sulphur to produce three key amino acids: methionine, cysteine and cystine. Without the S to build these amino acids, N creates toxic amides in the plant that greatly…

A 50-bushel crop can remove more than 50 pounds of P205 per acre. Growers using only seed-placed phosphate at a rate of 15 pounds per acre can slowly deplete the soil of phosphate. That can start to affect yield potential on the field over time. These plants, demonstrated at CanoLAB, were seeded the same day in a greenhouse and fed…

A dry summer and fall in certain areas of the Prairies created a high risk situation for herbicide carryover this spring. High spring moisture from increased snow fall will not help much because microbial activity does not occur, no matter the soil moisture level, until soil temperatures are 5°C and then only increase marginally until soils are warm. If little…

Both of these trays were seeded with kochia and then sprayed with glyphosate after emergence. The difference: The tray in front was seeded with glyphosate-resistant kochia seeds. Glyphosate resistant kochia is spreading and most kochia on the Prairies is already Group 2 resistant. For good long-term management and prevention of glyphosate-tolerant kochia escapes, use a rotation of broadleaf control products…

These photos from canola plots grown in clubroot-infested soils in Quebec show how rotation, especially for MS and S varieties, improves yield. Rotation also plays an important role for growers relying on R varieties in clubroot infested fields. Short rotations using resistant varieties will select quickly for clubroot pathotypes that are not controlled by the genetic resistance. This can rapidly…
