Early weed control is best. Even if growers don’t expect to seed for 10 days or more, they may want to consider a pre-seed burnoff now (as long as fields can support a sprayer) to get weeds at smaller stages…

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… -
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…

Fields taken out of pasture or hayland last year and planned for canola this year could have high wireworm and cutworm populations. Wireworms can wipe out a whole field of canola and no seed treatment or spray is registered for wireworm control in canola…

Don’t rush to broadcast seed. Canola seed placed into the soil at a uniform depth with starter fertilizer and light on-row packing is the best method for seed survival and……

Consider potential herbicide carryover before seeding canola on any field…
