  • Keep the Heat Coming

    Keep the Heat Coming Generally warm, dry conditions prevailed across the prairies last week and over the weekend which has helped advance crop development. Swathing is underway in southwestern and central Manitoba, southwestern Saskatchewan, and southern Alberta. A few of the very earliest fields in these areas have been combined. Swathing is just beginning in […]

  • Check Closer – It Might be Sunscald

    Sunscald has been appearing in some fields in many areas. It is important to diagnose because sunscald can make the plant appear riper that it actually is. Always examine seed colour change to determine maturity for timing of swathing. Sunscald occurs when plants are ripening during periods of stress such as heat. The main symptom […]

  • Premature Ripening? Might Mean Late-Season Disease

    It is important to scout fields and examine plants to know what is causing symptoms such as premature ripening. Don’t let the colour change of a small percentage of diseased plants affect the harvest timing of the whole field! Across the prairies, there are several reports of late-season diseases, especially sclerotinia and blackleg. In some […]

  • Using Canola as Forage

    Questions continue about cutting canola crops abandoned due to drought or frost damage for forage. Canola crops can make palatable feed and can be fed to cattle provided precautions are taken. On a dry matter basis, canola as a forage has a crude protein of 12% to 14%, and can be as high as 16% […]

  • Scout and Learn From the 2009 Crop

    Discovery of late-season diseases can help you evaluate you management decisions made earlier in the year and assist with management decisions for next year. Fields with high levels of sclerotinia should be noted and crop rotation should be evaluated. High levels of sclerotia returned to the soil this fall can increase the risk of sclerotinia […]

  • Drying Down Glyphosate-Tolerant Canola

    Particularly in Alberta, there are questions about the use of herbicides to dry down or desiccate glyphosate-tolerant canola plants, either an entire canola field or when present as weeds in cereal crops. There are no products registered as a desiccant on glyphosate-tolerant canola except Reglone. ALWAYS be Export Ready and avoid the use of unregistered […]

  • How to Swath with Variable Stages

    For growers faced with uneven maturity within fields, it may not be possible to swath all the crop in the 50-60% seed colour change window. In situations where uneven maturity is the problem, the best approach is to swath when the most mature plants are close to 60% seed colour change, provided that the least […]

  • Anchoring Short Canola Stands

    Questions are starting about swathing this year’s crop with low plant stands and shortened crop height as the ability to anchor the swath to the stubble will likely be hampered. To reduce potential losses from swaths blowing, keep the following recommendations in mind: Swath parallel to the typical prevailing winds in the area. Cut the […]

  • Swathing Early Under High Temperatures

    There have been reports of producers cutting fields that are too green, especially in the recent heat. Avoid the urge to swath too early, especially under high temperatures. The optimum time to swath is when the majority of the crop has achieved 60% seed colour change. Waiting for this stage allows the crop to enter […]

  • Combining in High Temperatures

    Some of the earliest fields in the southern prairies may be combined in the coming days. It is important to remember that canola storage can be a concern even at seed moisture levels considered dry when the canola is binned at high temperatures. Use aeration to bring down the temperature of binned canola. It should […]

  • Residue Management for 2010’s Canola

    The cold emergence period this spring was certainly challenging but in some fields was aggravated by poor residue management in the previous crop. As harvest gets underway, consider residue management in fields destined for canola in 2010. Good chaff spreading and straw dispersal can help ensure good soil to seed contact next spring. Stand establishment […]
