SaskOilseeds offered a free disease testing program this year and is currently investigating three canola diseases: clubroot, blackleg and verticillium. | File photo

Sask. canola group makes crop disease its major focus

SaskCanola amalgamated with the Saskatchewan Flax Development Commission this year to become SaskOilseeds

Free disease testing for farmers, field training days for agronomists and farmer-conducted on-farm research trials were the focuses of SaskOilseeds this past year. Research manager Doug Heath outlined the organization’s 2024 activity at Canola Week, held Dec. 3-5 in Saskatoon and online. ”We work on behalf of canola and flax farmers to fund crop research, […] Read more

Blackleg incidence in prairie canola fields, which is the percentage of plants in a field with symptoms, increased to 23 per cent this year from 12 per cent last year.  |  File photo

Blackleg was brutal this year

WINNIPEG — The wet spring on the Prairies provided nearly “perfect” conditions for blackleg to develop in canola crops. That’s why 2024 will likely become the worst year on record for the disease in Saskatchewan. “Ninety-two percent of crops we surveyed in Saskatchewan in 2024 had at least trace levels of blackleg,” said Alireza Akhavan, […] Read more

Crop disease tags along on soybean’s coattails

‘Honeymoon’ period for producers is ending as diseases such as phytophthora root rot make inroads following soybean expansion

Glacier FarmMedia – The worst phytophthora infection that Laura Schmidt of Manitoba Pulse and Soybean Growers has ever seen was just south of Souris. “Probably 25 per cent of the field was impacted,” the production specialist told field day attendees at the Westman Agricultural Diversification Organization near Melita. “One in four plants were dying off, […] Read more


Verticillium stripe is a fungal disease that infects roots and enters the plant’s vascular system. It’s now present in all three Prairie provinces.  |  Justine Cornelsen photo

Verticillium stripe in spotlight as threat grows

A U of A study just wrapped up, and four Canola Agronomic Research Program projects are now investigating the disease

Glacier FarmMedia – If you’re a canola grower on the Prairies, you know there are no chemical solutions or varieties to kill or resist soil-borne verticillium stripe disease. You may also know the handful of management practices that can thwart the disease to some extent. And if a crop has been damaged by it, you […] Read more



Testing wheat, barley and durum seed for bacterial leaf streak is one way to prevent infection, but it’s no guarantee.  |  File photo

Bacterial leaf streak disease persists; Alta. crops affected

The disease has caused economic yield losses in a small number of fields, but its presence could become a lingering issue for cereal growers

Bacterial leaf streak is not going away. The disease was present this summer in possibly “hundreds” of irrigated fields of barley, durum and spring wheat in southern Alberta, said Mike Harding, a plant pathologist with Alberta Agriculture. The disease caused economic yield losses in a small number of fields, but its presence could become a […] Read more

In 2022, Saskatchewan Agriculture staff discovered that verticillium stripe, a disease of canola, was commonplace in the eastern part of the province. This fall, producers in other regions have found the disease in their canola. | File photo

Farmers watch as verticillium extends its reach in Sask.

The canola disease appears to be moving west and north after being found in eastern part of the province last year

Anecdotal evidence suggests that verticillium is moving north and west across Saskatchewan. In 2022, Saskatchewan Agriculture staff discovered that verticillium stripe, a disease of canola, was commonplace in the eastern part of the province. This fall, producers in other regions have found the disease in their canola. “I’ve got verticillium in Davidson like you wouldn’t […] Read more

About 20 percent of all Manitoba fields surveyed had plants with symptoms of aster yellows — a disease spread by aster leafhoppers. | Tyler Wist photo

Disease survey finds elevated aster yellows levels in Manitoba

Clubroot levels in the province stay low, but a field near Roblin is highly infected with the soil-borne disease

Aster yellows likely reduced canola yields in some Manitoba fields this fall, as the disease was five times more common in 2023 than it was last year. Manitoba Agriculture plant pathologist David Kaminski released preliminary results of the annual canola disease survey for the province during a presentation in early September. About 20 percent of […] Read more

Wild varieties may hold disease resistance key

Wild cousins of domesticated crops may hold the key to new genetic traits that could help crops thrive in various conditions or stave off diseases and insect pests.Sabine Banniza is a professor at the University of Saskatchewan where she holds the Ministry of Agriculture Strategic Research Program (SRP) Chair in Pulse Crop Pathology. She has […] Read more
