• Some Heat, Some Rain, Then Heat Again Rainfall was reported in many areas of western Canada last week which halted combines temporarily but allowed much of the canola to be swathed under relatively ideal (damp) conditions. Rainfall amounts were variable with amounts generally ranging from trace up to two inches. A couple of locations in……

  • In Manitoba, approximately 80 to 90% of the canola is swathed with the exception areas around The Pas (about 50% swathed), Roblin/Russell areas (50 to 75% swathed), and the northern interlake region which is about 20 to 50% swathed. Overall approximately 15 to 20% of the canola has been combined and combining will likely become……

  • Remember that green seed percentage cannot be lowered once canola seed is in the bin. Therefore, growers must allow enough time to pass while canola is in the swath for chlorophyll to clear the seeds prior to combining. If ideal conditions exist, canola can be combined with good quality after lying in the swath for as……

  • Variable maturity within fields has been an issue all season in many regions so as combines begin the harvest it is important to take a good, representative sample (not just the edge of a field)  to know what the entire field is like. Field edges are often more ripe than other parts of the field.……

  • Reports of canola harvested so far indicate that seed moisture content is ‘dry’ (below 10%). 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 or when there is a lot of ‘foreign’ material (e.g. green weed seeds).……

  • Canola that has recently been swathed or those fields that are yet to be swathed will likely only be combined near the end of September and into October. Depending on the weather, storage could be a challenge. If canola is combined ‘tough’, it is difficult for aeration to bring down the moisture content substantially in……

  • Canola should not be stored in bins that were previously treated with malathion since canola oil has a strong attraction to the insecticide and will result in detectable residues. Malathion can move into canola seed from storage bin walls. Detection of malathion residue in canola seed above the allowable limit will result in rejected shipments……

  • There are reports near Maymont, SK about fungus feeding beetles on canola swaths. These beetles feed on fungus that grows on crop residue or damp seeds. Fungus feeding insects and mites cannot survive in dry grain. Chemical control is not necessary for fungus feeding pests in stored grain. Do not apply malathion or other chemical……

  • Straight cutting of canola is becoming more common in some parts of the Prairies (e.g. parts of the Peace Region in Alberta). For many fields this year this decision will already have been made, but for any late fields where this is still being considered, keep in mind the following four factors: Frost risk –……
