A 4-year research project at the University of Saskatchewan’s Crop Development Centre set the platform that will assist plant breeders in developing leaf blotch resistant oat varieties. Growing resistant varieties in combination with adequate crop rotation intervals will be the most effective, economical and eco-friendly...

Bleach (sodium hypochlorite) was most effective in killing clubroot (Plasmodiophora brassicae) spores at concentrations above 1.7%. Spray Nine was almost as effective, while 5 other products achieved greater than 95% control. Sanitation of equipment, vehicles, scouting tools and footwear is an important part of preventing the...

Seedling blight and root rot in soil-inoculated Rhizoctonia solani plots decreased soybean stand establishment by 48% and reduced yield by 52% compared to control plots with low levels of R. solani. No significant differences in disease severity, nodulation or yield loss were observed among the...

Lygus bug and chocolate spot disease can damage faba bean seed. Research found both organisms are widespread in central and southern Alberta. Seed damage occurs independently of each other, and is primarily caused by lygus bug. Seed damage caused by lygus bug (Lygus spp.) or chocolate...

For every 1-unit increase in disease severity rating on a scale of 1 to 5, yield loss in a susceptible variety was 17.2% and pod loss was 13.0%. Disease severity was lower and seed yield was 120% to 128% higher in the moderately resistant to...

Basamid (dazomet) soil-applied fumigant was effective against clubroot and seedling blight in canola. Basamid appears to have good potential as a tool to maintain canola yield and reduce the spread of clubroot where the disease is concentrated, usually at field entrances. Clubroot, caused by the obligate...
