Growers switching crop plans this spring should consider their herbicide use last year, especially last fall, before seeding canola on any fields not originally planned for canola. Canola is sensitive to many residual herbicides, and herbicide carryover can be higher than expected when fields are saturated…

Before growers take steps to encourage earlier maturity (some of which may hamper yield potential), they should first calculate whether these measures are necessary. Canola seeded any time in May has a good chance of reaching maturity. If growers decide that measures to hasten maturity are warranted, here are steps to consider:…

Once crops are seeded, check fields on a twice weekly basis for flea beetles and cutworms. Canola in the western Prairie will emerge quickly, and highs for the region are in the high teens for the coming week. This will promote more insect activity… -
Flea beetles are the most chronically damaging insect pest of canola in western Canada. Direct losses to oilseed production average 8-10% of the annual crop yield, and in outbreak years flea beetles can cause hundred of millions of dollars damage.The nominal economic threshold for flea beetles in canola crops in Canada is an average defoliation level of 25% or more… -
It’s true, early seeded canola does tend to produce higher yields, but that performance edge depends on good seed placement and stand establishment. Mudding in or broadcasting just to seed……

Peace (B.C. and Alberta): After good snowfall this winter, the Peace region has better soil moisture than it has had in years. Some peas are in the ground and canola……

A ground cover of weeds may do growers a favour on fields too wet to seed. Weeds are better than evaporation in getting rid of water, especially from deeper soil layers. But don’t let these weeds get too big, as they may be difficult to control or prevent from going to seed once flowering starts…

Some reports suggest sulphur fertilizer supplies may be limited in some areas this spring. If growers have trouble getting all the sulphur they need prior to seeding, divide what you have across all your canola acres, then top up with an in-crop application of ammonium sulphate…

For all canola, whether seeded early or late, growers want to make sure they seed shallow — less than 1” deep — for faster and more uniform emergence…
