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...

When stripe rust severity was low, resistant and intermediate wheat and barley varieties did not suffer significant yield losses. When leaf spot and stripe rust disease levels were high, a foliar fungicide application was necessary to reduce yield losses even on resistant varieties. Seven spring wheat...

A ≥2 year break from clubroot-resistant canola resulted in a 95% decrease in clubroot resting spore concentrations. In the third year after the harvest of clubroot-resistant canola, resting spore concentrations were similar to those of host-free control plots. Previous small plot research showed the value of...

Canola yield with a three-year break between canola crops was significantly higher than a tighter canola-barley rotation by 18 bushels per acre. Growing clubroot resistant canola in a tight rotation was not a strategy that could be implemented to keep clubroot spore populations low, and...

The maintenance of a naturally occurring clubroot nursery provided an evaluation site for over 60 canola lines, varieties and cultivars over 4 years in southern Alberta. The nursery site was also used extensively for training and extension activities. When you get served lemons, make lemonade. In...

A set of clubroot surveillance practices was developed for effective monitoring of the occurrence and severity of Plasmodiophora brassicae in commercial fields. Clubroot, we’re watching you. A major focus of research into clubroot disease caused by P. brassicae is surveillance of the geographic spread of...
