White mould control requires flexible timing under Prairie conditions
Trials in dry beans and soybeans show that spray timing shifts depending on the number of planned passes
White mould tops 2025 disease threats in Manitoba soybean fields
White mould, a.k.a. sclerotinia, was found in nearly two-thirds of surveyed fields, with eastern and southwestern regions hit hardest
White mould was found in nearly two-thirds of surveyed Manitoba soybean fields during the 2025 growing season, but at a relatively low intensity in most cases.
Canola growers face rising verticillium stripe threat with few options
In 2025, the Prairies experienced its worst year on record, sparking renewed focus on yield loss, resistance and management
After a severe 2025 outbreak, verticillium stripe is drawing attention at Prairie agronomy meetings as researchers warn of uncertain yield impacts and slow resistance progress.
New Syngenta fungicide targets anthracnose, white mould, Ascochyta blight
Lentil growers in Canada have a new option for controlling three major disease threats to the crop.
Manitoba canola embattled by verticillium
Verticillium stripe pressure has been growing in the province and growers have precious few tools to protect their crops from disease
Verticillium stripe pressure has been growing in Manitoba, and canola farmers still have precious few tools to protect their crop from the disease.
Researchers chase resistance to bacterial leaf streak
Manitoba researchers are testing whether known resistance genes can be effective against bacterial leaf streak in cereal crops
Bacterial leaf streak is re-emerging in cereal crops on Canada’s Prairies. With no fungicides or resistant varieties, researchers are testing plant genes for future control of the disease.
Detector in development to spot fusarium head blight’s signature toxin
A portable machine to identify contaminated kernels is an eventual goal for research at the University of Saskatchewan
A portable machine that would allow wheat growers to identify kernels contaminated with fusarium head blight’s signature mycotoxin is in development at the University of Saskatchewan.
Regulatory model “broken” in Canada – says BASF
Farmers and agribusiness in Canada have long expressed frustration with Canada’s regulatory system

Canola gets good news, bad news on sclerotinia fungicides
Sclerotinia samples show various levels of resistance against common fungicide chemistries, including some concerning results from Manitoba
Sclerotinia in Canadian canola fields is still mostly responding to three major fungicide groups, but there are some populations less sensitive to the chemistries, AAFC project shows
Verticillium may undermine canola blackleg resistance
Co-infections with verticillium stripe may compromise blackleg resistance protection in canola, new Manitoba research 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.
