Growers will learn a lot from two field checks during the first few weeks after emergence. Scout fields 5 to 10 days after seeding when canola starts to emerge, looking for early threats. Then go back again two to three weeks after seeding to assess the stand… -
In areas with dry top soil conditions, growers often wonder whether to seed deeper to chase moisture. This approach differs based on the date and typical rainfall patterns…

The first two weeks of May are the ideal time to seed canola, based on long-term yield results from the Prairies. This has been shown in Canola Council of Canada research as well as crop insurance results… -
Growers uncertain about which canola seeding rate to use should start with 5 lb./ac., then tweak. See the full article on this topic…

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…
