Diseases
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…
The fungal disease Verticillium longisporum was first detected in Canada in a canola field on a farm in Manitoba in 2014. The results of a subsequent national survey led by the Canadian Food Inspection Agency (CFIA) and released in 2016, detected the presence of the pathogen V. longisporum in varying…
Aphanomyces disease in peas and lentils is a widespread and serious problem across Western Canada. In 2017, even with dry conditions in many areas, the disease remained a significant problem in peas, with crop and yield losses in infected fields remaining high. In lentils, the incidence and severity was reduced…
Multiple parts of Saskatchewan saw clubroot infections in 2017, and now the Ministry of Agriculture is trying to tackle the problem before it escalates by promoting best-management practices. | READ MORE
A team of researchers led by University of Guelph plant scientist and professor, Karl Peter Pauls, recently completed a three-year research project to tackle one of Ontario’s most costly bean diseases: anthracnose.
Blackleg levels on the Prairies have been going up, but research information on blackleg races and cultivar resistance, plus a new cultivar labelling system and a new diagnostic test, can help bring those disease levels back down.
Bees can provide a helping hand to farmers with a new green technology to fight against major fungal diseases such as sunflower head rot and grey mould.
It doesn’t matter how you look at it, clubroot is an ugly threat to the Canadian canola industry.The disease does unsightly things to the plant, producing galls and deformities that will effectively choke it to death.The effect of clubroot on yield is just plain nasty — yields can be reduced…
In 2016 the milder winter conditions resulted in early leaf and stripe rust infections in Tennessee and Kentucky. This resulted in rust spores being blown into Ontario earlier than we typically see. By mid-May 2016, stripe rust was prevalent in most areas of southwestern Ontario. Growers who selected tolerant varieties…
When it comes to fighting Fusarium graminearum, our crops may soon have some new tiny but powerful allies. Research by Manish Raizada at the University of Guelph is providing the foundation for commercializing some anti-Fusarium bacteria as biocontrol products. As well, a student in his lab discovered an amazing mechanism…
As problems with Fusarium head blight (FHB) continue to increase on the Prairies, so does the need to deal with Fusarium-infested grain and screenings. Preliminary results from a Saskatchewan study are pointing to a possible way to extract value from these wastes while potentially reducing the risk of spreading the…
High-value specialty spice crops like coriander and caraway are important diversification options for growers in Saskatchewan. However, one of the biggest challenges in growing a profitable crop is blossom blight disease, which can cause significant yield and quality losses for growers. Through a buyer levy program developed and implemented by…
