  • Be Export Ready – Keep Pre-Harvest Intervals Top of Mind

    Issues of the week: August 11, 2010 — Swathing is underway in parts of Alberta (Peace) and Saskatchewan, but most regions are 1-2 weeks behind. Fields in wettest areas are delayed 3-4 weeks. More heat is needed to speed crop development. Combining of April-seeded fields has started in Manitoba. This week, we’ve got swathing tips […]

  • Crop and weather updates:

    Peace (B.C. and Alberta): Hot, dry weather prevailed last week. Swathing has become general in the earliest and thinnest crops and will become general in other areas within a week or so. Alberta: Crops in the south and central region look good to excellent. Farmers are cautiously optimistic because crop development is 2-3 weeks behind. […]

  • Quick Hitters:

    Late season spraying – adhere to pre-harvest intervals Pre-harvest interval (PHI) refers to the number of days that the crop should NOT be harvested after application of a pesticide. Harvest in this context means cutting or swathing, so this could also be called the pre-cutting interval. If the crop is harvested before the indicated interval […]

  • Clubroot shows up in resistant hybrids

    Growers who seeded clubroot-resistant hybrids should know that low-level infection — up to 8% of plants — is normal for these hybrids. These off-types will be scattered uniformly through the stand. If resistant hybrids have levels higher than this, a patch of susceptible volunteers is the most likely reason. Volunteer canola densities can easily exceed […]

  • Should growers straight combine a thin crop?

    Growers with thin crops are wondering whether straight combining is better than swathing. Straight combining tends to work best on thick stands with plants meshed together to prevent whipping in the wind. But thin stands are at risk of wind damage whether swathed or straight combined. When thin stands are swathed, often there isn’t enough […]

  • Should I use a pod-sealant?

    Questions continue about pod sealants. Limited western Canadian research to date has produced variable results. If farmers do use them, leave a test strip as a comparison and an assessment can be made to see if the sealant made a difference on yield. Ensure application timing is optimal and water volumes are adequate to maximize […]

  • What are those odd-looking plants?

    number of odd looking plants have generated calls and questions lately. Some are tall, monstrous looking plants. These are called off-types. Many seed companies conduct seed multiplication in the southern hemisphere and these off-types result when pollen transfer occurs with winter canola. Another anomaly showing up is aster yellows.  Affected plants show a bunched appearance […]

  • 7 swathing tips for 2010

    1.    Scout for disease prior to swathing. Assess levels to determine if premature ripening or pod damage from alternaria black spot may necessitate swathing earlier than normal — before seed shatter starts. Fields with lots of diseased plants may also be poorer candidates for straight cutting due to the increased shattering risk. 2.    Hail damage […]

  • When to swath multi-stage crops

    Many fields in the rain-soaked regions have advanced crop on the high ground and much later crop in the low ground. These fields require some harvest planning. Does a grower swath the high ground first and the low ground a couple weeks later? That may be the best option as long as the low ground […]
