The Ontario Ministry of Food and Rural Affairs (OMAFRA) is conducting its annual survey sampling grower corn fields to determine ear mould incidence and the occurence of mycotoxins in grain. 
The recent identification of a new midge in Prairie canola crops has led researchers to revisit previous detections of what was thought to be swede midge. Boyd Mori, a research scientist with Agriculture and Agri-Food Canada (AAFC) in Saskatoon, thinks most of the suspected swede midge detections in Western Canada…
As growers know, FHB fungi can produce toxins that limit the grain’s use for food and feed. The grain’s concentration of deoxynivalenol (DON), the most common FHB toxin, is the critical limiting factor for most buyers.
Recent rains result in increased risk for root rot, as well as black point or smudge in harvested wheat. Winter wheat yield reports are below average, but yield and quality are better than expected considering the heat and moisture stress endured throughout the season in Ontario, according to OMAFRA's latest…
Prairie cereal growers in warm, humid zones will be on the lookout for Fusarium outbreaks in the flowering stage. 
Blackleg disease is on the rise. Research scientist Gary Peng, with Agriculture and Agri-Food Canada (AAFC) in Saskatoon, says tighter canola rotations have meant an increase in virulent races of the blackleg pathogen.
Across most of the Prairies, cereals grown in shortened crop rotations will continue to be vulnerable to Fusarium head blight (FHB) as a result of more severe FHB incidence in 2016, according to Alberta Agriculture and Forestry's update. 
Early season root rot has been reported in both soybeans and sunflowers, according to Manitoba Agriculture's Insect and Disease update. 
Whether or not to use fungicide at the same time as herbicide to protect from blackleg infection depends on a number of factors. The most recent disease update from Manitoba Agriculture includes questions growers should ask themselves when it comes to protecting their crop.
It was the best of times and the worst of times. The year of 2016 was certainly one of the worst of times for Fusarium head blight (FHB). High FHB incidence and severity was widespread across the Prairies, with durum wheat hit especially hard. By contrast, 2017 saw much lower…
Call Susie Li a dreamer, but the researcher at Alberta Innovates Technology Futures at Vegreville, Alta., has developed a way for a tiny nano-biosensor to monitor sclerotinia spore levels in canola and alert a grower with a telephone call.
Like most crop diseases in 2017, infestation levels and severity of stripe rust were low, because of the warm, dry weather that occurred in many parts of Alberta and Saskatchewan. Going into 2018, the risk of stripe rust developing in Alberta will depend on the spores blowing up from the…
Rust is one of the issues targeted in a major project to advance disease management in fall rye. Not only is this project breaking new ground by breeding for rust resistance in western Canadian rye cultivars, but the research could also help shed light on some of the basics about…
Fusarium head blight (FHB) on canaryseed is on the radar for growers and researchers.  Although it was only recently confirmed at the University of Saskatchewan by Paulina Cholango Martinez and Randy Kutcher, Kevin Hursh, executive director of the Canaryseed Development Commission of Saskatchewan, says that Fusarium has been showing up…
Although oats are less susceptible than other cereals to Fusarium head blight (FHB), this disease can impact oat yield and quality when conditions strongly favour the disease – as they did on the Prairies in 2016. So, researchers are working to better understand FHB in oat, to develop oat varieties…
