The most significant variable associated with mycotoxin test results comes from incorrect sample collection or uneven distribution of infected kernels in a load. 
Visible symptoms of clubroot have been confirmed in 37 Saskatchewan canola fields across the northern agricultural regions to date.
Clubroot continues to be a disease risk to canola crops across Alberta, with more than 2,700 clubroot-infested fields now confirmed, along with a few isolated cases in Saskatchewan and Manitoba. Although good clubroot resistant (CR) varieties have been available for about 10 years, there are an increasing number of fields…
The fungus Sclerotinia sclerotiorum, which causes stem rot, is a major economic disease in canola that impacts the crop across all of Canada’s growing regions.
The 2018 grain corn ear mould and vomitoxin (DON) survey found 60 per cent of Ontario grain corn samples tested low - less than two parts per million (ppm), for DON.
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. 
First detected in Ontario canola in 2016, clubroot is an increasing concern for the province’s canola growers. A University of Guelph research group is a key player in Canadian research to manage this devastating disease and is advancing knowledge about Ontario’s clubroot situation.
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.
