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...
Eight of nine fungicides tested helped to manage Fusarium root rot in soybeans in Alberta. Several soybean varieties were identified with partial resistance to Fusarium root rot. Root rot caused by Fusarium spp. is prevalent in soybean crops in Alberta. The objectives of this study were...
Research on root rot diseases of pulse crops is summarized to provide a brief description of the important pathogens and their management. In addition to existing tools such as seed treatment, crop rotation, and early, shallow seeding to manage root rot risk in the short...
Several fungicides were evaluated for control of cotyledon infection by Leptosphaeria maculans and blackleg disease of canola. Under controlled environmental conditions, fluopyram showed greater efficacy than fluquinconazole in limiting cotyledon infection, while regular seed treatments with Prosper EverGold or Helix Vibrance were ineffective. In field...
