Growers who seeded canola a couple weeks ago will want to start scouting now for emergence issues. Often if seed and seedlings are damaged by rots and blights, which tend to be a more common occurrence in cool soils, they will quickly dry up and disappear. You need to act fast to accurately diagnose the problem…

Even if growers don’t expect to seed any time soon, they may want to consider a pre-seed burnoff now to get weeds at smaller stages and before they draw down moisture and nutrients that their canola crops will need…

A good starting point for seeding canola is when the three-day average soil temperature in the seed zone is 4-5 C. Use a soil thermometer and take readings at 8:00 a.m. and 4:30 p.m. over a few days and average the results. Because canola is seeded at 1” deep, test the soil temperature at that depth…

If you plan to seed at 5 pounds per acre regardless of seed size, know the risks. Large-size seed planted at 5 pounds per acre may not achieve the safe minimum plant stand of 7 plants per square foot…

Herbicide carryover risk could be higher this year because some products may not have broken down as expected in 2011 due to extreme conditions. Also, with the increase in canola acres, some canola will go on land not planned for canola when growers made there herbicide decisions last year…

With Statistics Canada's forecast of a record 20.4 million canola acres in Canada in 2012, some of those acres may be going onto freshly-broken pasture land. Expectations will be very low for canola seeded into these conditions because of weed competition, low nutrients, low moisture, poor seedbed, poor soil quality and wireworms…

A level drill is important for shallow seeded crops like canola. Also inspect openers, hoses, tank gaskets, meter rollers and manifolds for wear. Check that the electronics work properly and are calibrated…

Canola on canola yields less, in general, than canola grown on any other stubble. Reasons for this yield drop could include one or a combination of the following factors: Disease, Insects, Fertility, Moisture and Weeds. Diversity of attack is key with a tight rotation…

If you’ve budgeted for hybrid seed and optimal herbicide, insecticide and fertilizer applications, and you’d like to spend a little extra to push yields, consider a higher nitrogen rate. This is the key message from a recent study by Neil Harker and 17 other scientists from across the Prairies…
