Tests to improve Sclerotinia sclerotiorum control

KEY RESULT: Heads Up, a resistance activator applied to seed, was found to enhance resistance against Sclerotinia sclerotiorum causing white mould in dry bean, but showed no benefit for canola. Adding a micronutrient to a foliar fungicide improved control of S. sclerotiorum for two of the six fungicides tested. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Improving Sclerotinia...

Fumigant may be practical treatment for small clubroot patches

KEY RESULT: Soil fumigation with metam sodium can reduce clubroot severity and improve plant health in the subsequent canola crop. But because of high rates required and high cost per acre, fumigation may have a role in the eradication of localized or isolated areas of infestation. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Toward a Strategy for Reducing...

Toward matching clubroot resistance to pathoypes in the field

KEY RESULT: Researchers developed the Canadian Clubroot Differential (CCD) Set, which represents an improved system for the identification of new virulence profiles of Plasmodiophora brassicae and their classification into pathotypes. The CCD Set is an important new tool that can be applied directly on the ground by the sector, including agronomists, breeders and researchers. PROJECT...

Clubroot nursery at Brooks provided natural test site

KEY RESULT: The maintenance of a naturally-occurring clubroot nursery provided an evaluation site for over 60 canola lines, varieties and cultivars over four years. The nursery site was also used extensively for training and extension activities. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Supporting continued development of clubroot-resistant canola and early detection of clubroot outbreaks,” Michael Harding, Alberta...

Mapping the spread of clubroot

KEY RESULT: A set of clubroot surveillance practices was developed for effective monitoring of the occurrence and severity of P. brassicae in commercial fields. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Clubroot surveillance and epidemiology,” Stephen Strelkov, University of Alberta FUNDING: Growing Forward 2 Clubroot, we’re watching you. A major focus of research into clubroot disease caused by...
