  • Dry conditions elevate herbicide carryover risk

    Plant establishment


    Residual herbicides need a moist environment for herbicide breakdown to occur within the expected time-frame. In dry conditions, the two major breakdown methods – hydrolysis or microbial degradation – will slow down, which elevates the carryover risk.

  • What is seed dormancy and why does it matter?

    Plant establishment

    Dormancy happens when a canola seed experiences unfavourable germination conditions and ‘decides’ not to invest in germination until a later date. This is the main contributing factor in the persistence of volunteer canola, which may not germinate for years after the seeds first fall to the ground.

  • Consider yield and profit when choosing a seeding rate

    Plant establishment

    A target of five to eight plants per square foot allows for the loss of a couple of plants to frost, insects or other establishment threats while maintaining yield potential. This seeding rate is extra insurance to reduce risk. This target density range is also wide enough to allow for some uncertainty due to emergence percentage and seed size variations within a seed lot. Here are the economic considerations for five to eight versus two to three plants per square foot…

  • Herbicide carryover, sprayer contamination or something else entirely?

    Plant establishment

    Injury from herbicide residue in the soil can only occur in fields with a history of Group 2, 4, 5 and 14 herbicide applications. While soil characteristics and dry conditions can extend the at-risk period for these herbicides, carryover issues often occur when required recropping intervals are not followed. For example, Roundup Ready or Liberty Link canola cannot be seeded on fields that had Group 2 imazethapyr (Pursuit, Odyssey) the previous season. Here are typical symptoms for canola damaged by herbicide residue from these 4 groups…

  • Scouting 7 to 21 days after seeding: What to look for?

    Plant establishment

    With warm soils, decent moisture and 1” seeding depth, emergence can occur about a week after seeding. If emergence is slow or patchy, scout to find out why. The first 21 days are critical to a successful canola crop.
