Farmers at CanoLAB had a hands-on look at canola pests and problems

Grainews field editor Lisa Guenther attended the Canola Council of Canada’s annual learning event CanoLAB at Lakeland College in Vermillion on February 22. CanoLab offers a chance to see live plants and insects up close, while they talk with Western Canada’s top researchers and extension workers about current production issues. Watch the Canola Council’s event […] Read more


Cleavers can have a negative impact on canola and pulse crops.

Controlling cleavers without quinclorac

With quinclorac off of the herbicide menu, farmers will need to use other tools

Last spring, the Western Grains Elevator Association (WGEA) and the Canadian Oilseed Processors Association (COPA) advised growers that they would not accept quinclorac-treated canola grown and harvested in 2016. The reason for this announcement was to make sure that grain shipped to customers in other countries remains in compliance with regards to Maximum Residue Limits […] Read more

Back to the agronomy basics in canola

Experts advise growers to focus on quality seed and nitrogen before less conventional inputs

Canola growers have been asking agronomists questions about promoted products. Do they work? And if so, are they worth the additional cost? Two researchers, Murray Hartman, oilseed specialist with Alberta Agriculture and Forestry, and Neil Harker, research scientist, weed ecology and crop management, Agriculture and Agri-Food Canada, conducted a study to test the inputs that […] Read more


farm equipment seeding canola

How do you set a good seeding rate?

Have a targeted plant population in mind for this season? Remember that several post-seeding stresses, including cool temperatures (frost), weeds, moisture and insects, might keep your plant stand from fully establishing. And while some of these issues, like weather, may be beyond your control, insect and disease pressure can be managed with the right seed […] Read more

A plug of sclerotinia mycelium is attached to a canola stem with Parafilm.

Measuring sclerotinia resistance

How exactly do researchers and plant breeders separate the susceptible from the partially resistant? They use the stem test. The stem test simulates natural sclerotinia infection of canola, Lone Buchwaldt of Agriculture and Agri-Food Canada explains. Typically spores colonize petals that adhere to the plant stem. The leaf axle is a hot spot for infections, […] Read more


CPT small plot data is now online

CPT small plot data is now online

Small plot data from the 2016 Canola Performance Trials has been posted online. At the CPT website you can look up average yield, height, lodging and days to maturity for tested canola varieties. Filters on the website let you look for results in specific locations, and directly compare one variety to another. These small plots […] Read more

Scout fields before seeding, to see if the canola residue has pseudothecia — tiny black dots that release spores.

Slowing blackleg resistance with rotation

Labelling canola seed could help farmers slow the development of genetic resistance

As blackleg resurges in Western Canada, canola growers and agronomists have been calling for seed companies to label the blackleg resistance genes on their varieties. Those labels would allow farmers to rotate resistance genes when one resistant variety breaks, the thinking goes. “We’ve been engaged with the industry over the last few years to see […] Read more


Look for cankers at swathing time. Farmers who scout regularly and don’t find blackleg might want to stick with similar canola varieties.

Managing blackleg on the farm

Clint Jurke of the Canola Council of Canada offers producers three tips

Clint Jurke, agronomy director for the Canola Council of Canada says the industry is “losing millions of dollars in terms of canola yields every year due to blackleg.” The disease is also a trade issue, and we need to improve control as much as possible, he adds. “We really want growers to look at what […] Read more

Mike Nelson of Westaskiwin, Alta., had the highest canola yield among contest participants, but the challenge continues to hit the 100 bushel target.

Canola 100 Challenge still waiting for a winner

Canola 100: The top yield was 81.4 bushels per acre in 2016. Will we have a winner next year?

Fortunately there’s next year. While there was no 100 bushel canola yield winner in the first-ever 2016 Canola 100 challenge, organizers say that isn’t necessarily all bad, as the interest, excitement and momentum will carry on in 2017. None of the 21 western Canadian farmer finalists who registered for the high yield contest produced a […] Read more
