Field scouting advised for physiological leaf spot
Producers should check for pathogen or physiological factors in order to determine disease severity in winter wheat fields
Get the most from fusarium head blight risk maps
Fusarium head blight forecasts offer key information when Manitoba farmers are trying to decide whether they need to apply fungicide against the disease in their 2025 cereal crops
Fusarium head blight forecasts offer key information when Manitoba farmers are trying to decide whether they need to apply fungicide against the disease in their 2025 cereal crops.
Experts doubt FBI’s claim that crop fungus smuggled by Chinese students is a threat
A biological sample that a Chinese researcher was accused of smuggling into the United States and that prosecutors cast as a “dangerous biological pathogen” is a common type of fungus already widespread in U.S. crop fields that likely poses little risk to food safety, experts said.
Managing diseases in alfalfa
From seedling issues to stand die-off, understanding the timing and symptoms of alfalfa diseases can help protect yield
Understanding the multiple potential disease pressures on your alfalfa stand can help you improve its yield.
Corn has come a long way over the past 9,000 years
Practical Research: The fusarium we see in small cereal grains is the anamorph of the pink mould seen in corn
Consider that if you grow corn after wheat or vice versa and have a wet summer or fall, be prepared for possible outbreaks of pink mould/fusarium head blight in either crop in such a rotation.
Fungicide, glyphosate don’t hurt your hard red wheat quality
Sure, the results of this study aren’t all that surprising: everyone expected weather and genotype to be the most impactful factors on wheat quality. But this research hadn’t been done before, so it offers up the good news that fungicides and glyphosate aren’t making things worse.
Researchers scramble to understand verticillium in Canada
Disease is a relative newcomer to Canada and has been the subject of little research globally
Justine Cornelson of BrettYoung Seeds says verticillium is one reason Manitoba saw disappointing canola yields last year. The disease needs to be the subject of more research, since little has been done to date.
Canola and pulse diseases saw the usual culprits in 2024
Prevalence, incidence and severity numbers must all be taken into account to determine how much worry a disease should prompt
This year’s growing conditions threw many challenges at producers, one of the biggest being crop disease. Pulses and canola were hit hard, seeing high numbers of fields with disease across Saskatchewan. Root rot and blackleg had an average of more than 90 per cent prevalence, while mychosphaerella/ascochyta complex and anthracnose weren’t far behind. Alireza Akhavan, […] Read more
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 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
