  • What to do first, seed or control weeds?

    Issues of the week With soggy conditions, seeding is at least a week away for many growers across the Prairies. That raises an important question: Should growers seed as soon as they can or control all those weeds first? Applying a pre-seed burnoff as soon as those already-emerged weeds resume active growth may be more […]


  • Crop and weather update

    Peace (B.C. and Alberta): Most of the Peace is forecast to have below zero temperatures over the next few nights, and cool days (below 10ºC). Snow is forecast for some areas. Lack of moisture continues to be a concern in the east. Canola seeding is half complete in central and eastern areas, but just getting […]


  • Quick hitters

    —Light frosts likely won’t cause significant damage to emerged canola — yes, there is some emerged canola here and there. Growers with emerged crop should monitor fields a few days after any frost to ensure the crop has avoided significant mortality. For more on frost damage assessment, click here.

  • Look closely to assess weed size and number

    Lots of crop scouts say fields don’t appear to be “greening up” that much with weeds, but once you get out and scout closely there are lots of annuals emerging, and some perennials and winter annuals are more advanced than expected. Erin Brock, CCC agronomist for the Peace region, took these photos (see below) this […]


  • Should growers control weeds first, then seed?

    That’s a tough decision. We’re heading into the ideal time for seeding canola based on past research and crop insurance data. Manitoba crop insurance numbers show that canola seeded the first two weeks of May typically yields the highest. The table below, taken from the Canola Council of Canada factsheet Seeding canola: The ideal timing, shows the […]


  • Know herbicide carryover risk in fields for canola

    With many growers upping their canola acres, canola is often going on fields that were not planned for canola when growers were doing their herbicide applications last year. Check herbicide records to see if the field had a group-2 product last year, particularly a known residual product such as imazethapyr found in Odyssey and other […]


  • Calibrate the drill between crops and seed lots

    Canola can reach its yield potential with a stand of 7 to 14 plants per square foot. To hit that target, growers may need a different pound-per-acre seeding rate for each seed lot. That’s because canola seed can range in size from 3 grams or less per 1,000 seeds all the way to 6 grams […]


  • Seed a few strips 1 MPH slower

    We understand that in the spring rush, seeding slower doesn’t make sense to many growers. So for growers not prepared to slow down for the whole farm, we encourage them to try a few strips at a slower speed. Mark off these strips and keep that speed difference in mind when doing stand establishment scouting […]


  • Clubroot management starts with clean tools

    Clubroot-resistant varieties came to market for this year, providing growers another tool against the disease. But cleaning dirt from tillage and seeding equipment is still the first line of defense against the spread of clubroot. These tools are the primary carriers of infection. At a minimum, growers should knock off soil lumps and loose soil […]
