  • Map of the Week – Lows

    A few localized areas of the Prairies had a light frost over the past week. This is not usually enough frost to warrant a change in harvest plans.

  • Swath later for a big boost in yield

    Canola fields swathed at 60% seed colour change (SCC) on the main stem can yield 8% more than fields swathed at 30% SCC. That’s according to Canola Council of Canada research from the early 2000s. The yield difference could be even higher with lower plant populations because with fewer larger plants more of the yield will be in the side branches.

  • Late-season insects and pre-harvest intervals

    We had reports this week of bertha armyworm at higher numbers (maybe not at thresholds) in some very localized areas, lygus (it’s getting late), flea beetles (don’t spray them, it won’t help for next spring) and aphids (probably don’t spray them either). While doing a pre-harvest scouting for disease, take a look at the insect […]

  • Take time for a harvest disease survey

    If you didn’t get a chance to to the pre-harvest disease survey in canola fields, swathing can also be a good time to check. Get out of the swather once per hour to stretch your legs and check for disease. Clip a few stems for blackleg. Dig up a few plants to check for clubroot galls or foot rot. Give those plants a complete scan for other diseases.

  • Swathing after a frost

    Frost on pods can stop plant development and lock in green. It can also cause pods to split. However, a light frost may have no effect at all, and the crop will be better left to mature fully before swathing.

  • Put canola on aeration immediately after combining

    Ideally, growers will want to put canola on aeration as soon as it comes off the field. Cooling hot grain within the first 24 hours is important for safe long-term storage. Removing moisture that sweats from all canola — but especially tough canola (10-12% moisture) — is also important. Conditioning achieves both of these steps. […]

  • Stress management and help lines

    Time management, weather, family and economic stresses can pop up often for farmers. Stress can be a big factor in mental health. Contact these help centres for any mental health concerns.

  • BeGrainSafe: Maintain a strict “bin entry” procedure

    The best move is to stay out of bins while they’re being filled or emptied. Usually the only time a person feels the need to enter a bin is if grain is bridged or crusted. This can be a very dangerous situation, especially if a wall of grain is released and buries a person. CASA provides these bin-entry basics….

  • Send samples into the CGC Harvest Sample Program

    The Canadian Grain Commission (CGC) Harvest Sample Program monitors hundreds of samples each year to make sure quality standards are upheld in delivered grain. Farmers who sign up and submit samples get the following for free:

    –dockage assessment on canola
    –unofficial grade
    –oil, protein and chlorophyll content for canola

  • Use CPT data to help with seed decisions

    Crop walks through the summer may have given you an idea of which new canola varieties are of interest to you. While finalizing decisions, use the Canola Performance Trial data available at canolaperformancetrials.ca.

  • Harvest timing for an uneven field

    Canola fields with large areas at different stages lead farmers to ask the inevitable harvest timing questions: When do I swath? Should I leave it standing for straight combining?
