When to spray cabbage seedpod weevil

If you have to spray for the cabbage seedpod 
weevil, get the timing right

The first time Alberta grain farmer Jay Schultz remembers hearing about cabbage seedpod weevil was in 2005 at the University of Alberta when Dr. Lloyd Dosdall warned that it could become a major pest in the province. Schultz, who farms 6,000 acres near Standard, Alta., said that he never really paid attention, that is, until […] Read more




Learning at CanoLAB

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

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



Canola left out in your field? Make it count

You probably don’t even want to think about that canola that’s still out in the field this winter. But someone else is thinking about it. The Canadian Grain Commission is studying the impact of snow on canola quality. They’re looking for samples of canola from the 2016 growing year that has overwintered. CGC researchers are […] Read more


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



More sclerotinia resistance coming soon

Researchers are identifying lines with more-robust sclerotinia resistance

There’s good news on the horizon for growers and agronomists wrestling with sclerotinia in canola. Researchers with Agriculture and Agri-Food Canada (AAFC) have identified several canola lines with more-robust resistance to sclerotinia. They’ve also learned more about the sclerotinia pathogen and the sclerotinia resistance genes found in some canola lines. Researchers screened nearly 500 Brassica […] Read more


Farmers frustrated by sclerotinia

Sclerotinia was rampant in 2016,
 sometimes even for farmers 
who sprayed fungicide

If you had a tough time with sclerotinia in your canola crop this past year, you’re not alone. “It is still probably one of the most frustrating diseases that producers deal with,” says Barb Ziesman, provincial specialist in plant disease with Saskatchewan Agriculture. The environment was perfect for disease development across Saskatchewan, says Ziesman. Saskatchewan Agriculture’s annual canola […] Read more
