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…
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.
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…
Researchers led by Ahmad Fakhoury, associate professor of plant pathology and fungal genetics at Southern Illinois University Carbondale analyzed soil samples from 45 soybean fields in Illinois, Iowa and Minnesota. They collected samples from symptomatic patches in fields and from adjacent areas where soybean sudden death syndrome (SDS) foliar symptoms did not develop.…
Resistant soybean varieties have helped farmers manage soybean cyst nematodes (SCN) for decades. Almost all SCN-resistant soybean varieties possess the same resistance genes, from a soybean breeding line called PI88788.Recently, Iowa State researchers analyzed 25 years of data, from tens of thousands of four-row variety evaluation research plots, to look…
Wheat is an important crop in Canada, representing nine per cent of total farm cash receipts in 2015, and averaging 16 per cent of crop receipts in Canada from 2011 to 2015, according to Statistics Canada. And Fusarium head blight caused by Fusarium graminearum is the most important wheat disease.…
I work in Manitoba and we’ve been dealing with Fusarium head blight (FHB) for the last 25 years. In the 1990s, Manitoba started seeing severe infections. Those of you who are from Saskatchewan and Alberta, over the last two to three years, have definitely seen what it can be like…

Mary Burrows discusses the emerging pulse crop diseases she has seen in her home state of Montana, and what this could mean for western Canadian growers. Burrows also discusses the important of seed treatment in fighting these diseases. Click here for the full summary of Burrows' presentation.Don't forget to subscribe to…
In 2016, we conducted field surveys for root rot of pea and lentil in Alberta and Saskatchewan. In Alberta we surveyed 27 lentil and 89 pea fields during flowering, and 67 lentil and 68 pea fields in Saskatchewan.
Montana has seen a spike in pulse crop acres in the last 10 to 20 years. When I started 10 years ago, my crop responsibilities included spring wheat, winter wheat, durum, and maybe a little barley. Now wheat is becoming a rotational crop for pulse production.
