Bacterial leaf streak is re-emerging in cereal crops on Canada’s Prairies. With no fungicides or resistant varieties available, researchers are testing genes for future control of the crop disease.

Researchers chase resistance to bacterial leaf streak in Prairie cereals
With symptoms that mimic tan spot and rust, BLS often goes unnoticed
European seed firms hope lupins catch on in Prairie pulse rotations
Lupin could be a formidable feed option with its amino acid and fibre content
Lupins, not yet a crop of choice for farmers on the Canadian Prairies, outpace field peas and faba beans in terms of protein and starch level ratios, with up to 40 per cent protein and six per cent starch.
Ongoing research on chickpea-flax intercrop shows the mix reduces ascochyta blight
The intercrop works for reducing the disease, but Michelle Hubbard, an Agricutlure and Agri-Food Canada researcher, is still working on the why
Michelle Hubbard, an Agricutlure and Agri-Food Canada researcher, says chickpea-flax intercrop works to reduce ascochyta blight disease. She shares some theories on why.
Verticillium may undermine canola blackleg resistance
Verticillium stripe may compromise blackleg resistance protection in canola, new research out of Manitoba suggests
University of Manitoba research finds verticillium stripe in canola can break down blackleg resistance, creating challenges for disease management and yield protection on the Prairies.
Steps to stop blackleg in canola
Agronomists and canola growers have many proven steps to manage blackleg disease in canola. Genetic resistance has been an extremely effective tool, and will remain so — as long as that resistance matches the blackleg races in a field
Blackleg disease, caused by the pathogen Leptosphaeria maculans, is common in canola across the Prairies. It can cause very high yield loss in cultivars susceptible to the predominant blackleg races in a field. The two best defences are: Seed treatment and early-season fungicides can also help, especially if the first two are compromised. This article will […] Read more
Managing against fusarium takes a multi-part strategy
Tweaking fungicide timing could provide farmers with better control
Kelly Turkington, a longtime plant pathologist for Agriculture and Agri-Food Canada in Lethbridge, strongly supports the notion that an integrated approach to managing fusarium head blight (FHB) offers the best chance of success for cereal producers. Even so, Turkington says, in much of Manitoba and northeastern Saskatchewan, that strategy hasn’t always worked as well as […] Read more
Changing weather, changing varieties
With growing conditions in flux, adaptability is a consideration for soybean developers
Climate change has had a huge impact on farm operations in Western Canada for some time. Those shifting temperatures and weather patterns are also playing a key role in how future varieties are being developed. Grainews recently spoke with several prominent seed companies about new soybean varieties they have in the development pipeline and the […] Read more
Phytophthora’s Prairie evolution
For Manitoba the ‘honeymoon’ is ending as soy diseases such as phytophthora root rot arrive
Glacier FarmMedia — The worst phytophthora infection that Laura Schmidt of Manitoba Pulse and Soybean Growers has ever seen was in the province’s west, just south of Souris. “Probably 25 per cent of the field was impacted,” the production specialist told attendees at a Westman Agricultural Diversification Organization field day near Melita, Man. “One in […] Read more
New tools clear paths for canola’s next steps
Gene editing, artificial intelligence bring new efficiencies to the process
Recent technological advancements applied to canola breeding are already making selection a more efficient process. On an industry panel during Ag in Motion in July, asked about what’s next in the canola development pipeline, breeders and developers with Bayer spoke of the new processes and pathways they can now use to get there. One significant […] Read more
How a worldwide destructive cereal disease problem was solved in Alberta
In the story of ergot in wheat, barley and oats, the answer was simply 'copper'
When I was first hired by Alberta Agriculture as a diagnostic plant pathologist, I was told I would be primarily responsible for barley, oat, wheat and canola diseases. I was also asked to head up the provincial control program for bacterial ring rot of potato (BRR). The BRR program, run in partnership with the federal […] Read more
