  • Map of the Week – precipitation

    Up until yesterday, many parts of Alberta and Western Saskatchewan hadn’t received much rain over the past week. The Eastern Prairies got more. Rain events continue today in some areas.

  • Flea beetles: Why are some fields so bad in 2018?

    Early-seeded and slow-growing canola crops (usually due to dry conditions) have faced more flea beetle pressure this year, particularly in Manitoba and central Alberta. Flea beetle emergence tended to occur before most canola crops had emerged, so flea beetles concentrated on the earliest fields. And because topsoil moisture levels were fairly low, these canola plants were growing very slowly. Concentrated feeding and the plant’s inability to out-grow this feeding meant many crops were sprayed.

  • In-crop herbicide timing – scenarios

    In general, early weed control is best. A few early weeds emerging before or at the same time as canola plants are much more damaging to yield than lots of weeds emerging after canola plants are established. Those early-emerging weeds tie up nutrients and moisture valuable to the crop and can also out-compete the crop […]

  • Adding micronutrients can reduce herbicide performance

    Adding micronutrient solutions, especially zinc, to glyphosate is highly antagonistic to the herbicide.

  • Sprayer tank clean out – tips

    It is always good practice to clean the sprayer, especially between pre-seed and in-crop applications. Pre-seed burnoff programs often include three or four active ingredients, including Group 2 and Group 14 products ahead of cereal crops. You want to make sure these Group 2 and 14 products are completely cleaned from the sprayer tank, plumbing […]

    Combining pest control operations to save trips over the field may seem like good economic sense, but consider the following when making this decision:

  • What’s the Buff? Don’t spray sensitive areas

    Buffer zones or strips come in all shapes and sizes, and are designed to protect sensitive areas. Sensitive areas include permanent vegetation to maintain good water quality (riparian areas around rivers, lakes and ponds), control erosion (shelterbelts) or provide wildlife habitat. These areas are also typically habitat for pollinators and other beneficial insects.

  • Calculate seed survival

    As part of early-season scouting, assess plant density and percent emergence using the Canola Calculator plant survival calculator.

  • How long can canola seed sit in dry dusty soil?

    If soil conditions are dry and seed hasn’t imbibed water to start the germination process, there won’t have been enough water for the seed treatment to do anything but stay on the seed coat. Seed will still be viable and as soon as it rains, the clock starts ticking on seed treatment.

  • Manage the stand you have

    The key with a thin stand is to do what it takes to protect those plants. A stand needs a minimum of 4-5 plants per square foot to have the best chance to reach its yield potential. For a canola field at or below that plant population, consider lowering the action thresholds for insect, weed and disease management all season long.

  • Timely cutworm scouting and spray decisions

    See bare patches like this? Could be cutworms. Include cutworms on the scouting checklist for the first one to three weeks after emergence. Any later and management becomes more difficult because (i) spraying a registered insecticide is useless because the cutworms have developed beyond the feeding stage, and/or (ii) reseeding options are starting to be limited.

  • Check canola to be stored over summer

    Canola harvested last fall and still in on-farm storage can be at risk from heating. Hot outside weather will restart moisture movement within a bin, and if the canola has other risk factors – such as higher moisture and/or dockage – that concentrated moisture could lead to heating.
