Scouting now will identify early insect and weed pressure, identify establishment problems that may have been the result of drill settings or drill malfunction, and give you a benchmark to work from in the event of frost or wind losses…

The economic return will be higher than if the grower seeded over these large weeds and then took a chance on getting them sprayed before crop emergence…
-
It may be tempting to try other products, but these products are not registered. The whole point of controlling volunteer canola and early weeds is to give the canola crop a head start. But if unregistered herbicides are setting back the canola crop and thinning the stand, the whole purpose of a pre-seed burnoff is compromised… -
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…
-
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…

Consider potential herbicide carryover before seeding canola on any field…

Glyphosate works best when applied during daylight hours, and when temperatures are warm and humidity high. Read on for more weather and water tips to improve glyphosate performance…
-
Take a close look at the weed spectrum and stage in each field prior to seeding. It may be worth controlling those weeds before seeding, since early emerging weeds out-compete young canola for nutrients and moisture and can significantly reduce yield potential…
