Early weeds have large impact on canola yield potential. Past research has demonstrated an advantage of 3 bu./ac. for controlling weeds at the 1-2 leaf stage of canola versus the 3-4 leaf stage, and a 7 bu./ac. advantage for the 1-2 leaf stage versus the 6-7 leaf stage. Weed control timing has a huge influence on overall crop profit with…

The first few weeks of the growing season is a great time to police fields for suspicious weeds. Look for weeds that lived through the pre-seed burnoff or post-emergent sprays while others of the same species have died. These few weeds could be resistant to one or more herbicide groups, and it would be good to nab them early. Diversification…

Growers who seed before spraying may want to apply in the narrow post-seeding pre-emergence window. But if that window is missed, early in-crop weed management is essential to hold yield potential. Some yield potential is likely already lost to weeds by that time…
