Researchers investigated the efficacy and durability of canola lines carrying single and multiple clubroot resistance (CR) genes against 'new' and 'old' pathogen pathotypes. Stacked CR genes of different modes of action improved resistance and enhanced durability. Cultivar resistance is a cornerstone of clubroot management. Most canola...

In 10 of the 13 trials, double-nozzle configurations provided a 15% reduction in disease severity and up to a 60% increase in yield compared to the untreated control. However, droplet size and angle of application had no effect on field pea yield. Moderate water volume...

Application of foliar fungicides at the 2 to 4 leaf stage reduced blackleg disease incidence and severity, and improved yield on the susceptible Westar canola cultivar. On two resistant cultivars, however, this fungicide treatment reduced the disease but showed no yield benefit. Since resistant canola...

All of the fungicides and fungicide mixtures tested in field experiments reduced root rot in Fusarium infected soybean seedlings. Varieties were identified that could be used in plant breeding programs to develop Fusarium-resistant varieties. The potential for growing soybean in southern Alberta has increased with the...

“The agriculture industry in North America will take the first steps towards a dramatic change of direction during the next decade. The much anticipated shift to autonomous field equipment will eliminate the need for the enormous and expensive pieces of farming equipment currently used for...

Yield losses increased from 18% to 99% in the hybrid canola ‘73-15RR’ and 26% to 86% in hybrid ‘1950RR’ when disease severity rose from 2 to 5 compared with plants with severities of 0–1. Understanding the yield loss relationship with blackleg severity will help agronomists...

Research conducted over the past decade set the foundation for today’s clubroot management practices. This research covered the potential of biofungicides/fungicides, cultivar resistance, and crop rotation for management of clubroot disease caused by Plasmodiophora brassicae. Synthetic fungicides ineffective The fungicides Allegro and Omega (fluazinam) and Ranman (cyazofamid)...

Fusarium solani f. sp. pisi and F. avenaceum were the most aggressive species on CDC Meadow pea. Both F. solani f. sp. pisi and F. avenaceum caused significant disease symptoms on pea, chickpea, dry bean, and faba bean, but not on cereal crops, soybean, green...

SaskCanola administered Growing Forward 2-funded blackleg research projects that concluded over the past year or so. Results from these studies make it possible for farmers to test for the predominant blackleg races in a field and use this information to make strategic decisions for the...
