  • Rotate herbicide-tolerant systems, limit seed-placed N

    Issues of the week With warmer temperatures forecast and with very good soil moisture across most of the Prairies, this will be a busy week of seeding. Growers don’t need to rush. As long as they seize the advantage of these conditions by taking the time to ensure precise, shallow seed placement  at an appropriate […]


  • Crop and weather update

    Peace (B.C. and Alberta): Seeding is near 90% complete in some eastern regions, but conditions are dry. North and far north regions are 20% to 25% complete, but have good moisture. Central Peace is 50% done at most. The west, in general, has more moisture. Seeding is about half done, but growers are holding off […]


  • Quick hitters

    Take caution when mixing glyphosates, especially those of different formulations (salt types). In particular, mixing premium glyphosate products with lower priced products may void the warranty on premium products. Click here to see a MAFRI table of glyphosate products and their formulations. Retailers will provide more information, including details for any glyphosate product not on this […]


  • Calibrate the drill between seed lots

    Canola thousand seed weight (TSW) can range from less than 3 grams up to 6 grams or more. This can have a dramatic effect on seeding rate.Click here to see a CCC video on the topic. To calculate an appropriate pound per acre seeding rate for each seed lot, use this formula: Seeding rate (lb./ac.) […]


  • Hit those cleavers early

    Cleavers have emerged and are growing rapidly in scattered fields across the Prairies. Derwyn Hammond, CCC agronomist for Manitoba, says some are three inches tall already. “If growers wait until in crop to control those large cleavers, they’ll have trouble,” he says. Know the weed spectrum for each field before seeding. If cleavers and other […]


  • Rotate herbicide systems in tight rotations

    Some growers are looking at tighter rotations for this year, seeding canola on fields that were in canola two years ago or, in some cases, last year. This is not a best practice for well-known reasons of disease build up and lower yields. In Manitoba, for example, canola on canola stubble yields 83% of the […]


  • Limit nitrogen in the seed row

    Many growers strive to apply all their fertilizer during the seeding pass. This one-pass system is a good way to save fuel, minimize soil disturbance and maintain the integrity of the seed bed, but it does present challenges for seed and fertilizer separation. Putting all seed and fertilizer down a single-shoot opener presents a high […]


  • Suspected cutworm actually a cranefly larva

    Here’s another example why proper pest identification is important. The “suspected” redbacked cutworms found in the Carrot River area last week turned out to be cranefly larvae, commonly called “leatherjackets.” They were the same size as cutworms but were at a more advanced stage than redbacked cutworms would be at this time of year. They […]
