An assessment of the fumigant metam sodium and a Brassica juncea-derived biofumigant as management tools for clubroot (Plasmodiophora brassicae) of canola (Brassica napus)
DownloadFall 2016
Clubroot of crucifers, caused by the soilborne parasite Plasmodiophora brassicae, is spreading across canola (Brassica napus) fields in Alberta, Canada. Dissemination of the parasite is associated with the movement of infested soil on farm and other machinery, with the disease generally...

Rutabaga (Brassica napus ssp. napobrassica (L.) Hanelt) is widely grown as a vegetable crop and animal fodder, and is reported to be an excellent source of clubroot (Plasmodiophora brassicae) resistance genes. In this study, the genetic diversity and clubroot resistance of 124 rutabaga accessions...

Plasmodiophora brassicae Wor. is a soilborne parasite causing clubroot of canola (Brassica napus L.), a serious disease managed mostly by planting clubroot resistant (CR) cultivars. Recently, new pathotypes of P. brassicae have emerged that overcome resistance, highlighting the need for a greater...

Factors influencing Plasmodiophora brassicae resting spore loads in soil and clubroot disease severity in canola (Brassica napus)
DownloadSpring 2015
Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of Brassica napus canola. Studies were conducted to increase understanding of the impact of various soil parameters and crop rotation regimes on P. brassicae inoculum levels and clubroot severity, respectively. In...

Clubroot disease, caused by Plasmodiophora brassicae, is a major threat to canola production. Cultivation of resistant cultivars is the key component in managing this disease. Canola is an important oilseed crop in the world; this includes the allopolyploid species Brassica napus L. (AACC genome,...

Identification and genetic mapping of resistance genes against Canadian pathotypes of Plasmodiophora brassicae in Brassica rapa and Brassica napus
DownloadFall 2022
Clubroot (Plasmodiophora brassicae) is an important disease of canola/rapeseed (Brassica napus) and other crucifers. In this study, resistance loci/genes effective against P. brassicae pathotypes 2B, 3A, 3D, 3H, 5C, 5X and 8J were identified and mapped via genotyping-by-sequencing, QTL analysis,...

Pathotypes of Plasmodiophora brassicae from clubroot resistant canola and assessment of amisulbrom for clubroot control
DownloadSpring 2021
Clubroot, caused by Plasmodiophora brassicae Woronin, is an important soilborne disease of canola (oilseed rape; Brassica napus L.). In Canada, clubroot management relies heavily on the planting of resistant cultivars, but since 2013, resistance has been broken in an increasing number of fields....

Spheroidal gall formation and seedborne infestation by Plasmodiophora brassicae as overlooked aspects of clubroot biology and epidemiology
DownloadFall 2011
Plasmodiophora brassicae, the causal agent of clubroot, can infect many species of the Brassicaceae. Infection results in the formation of galls on the roots of susceptible plants. Most galls are spindle-shaped, but spheroid galls can also develop and are regarded as resistance structures....

Fall 2021
Clubroot, caused by Plasmodiophora brassicae, is an important soilborne disease of canola (oilseed rape; Brassica napus). The effective and sustainable management of clubroot requires a deeper understanding of clubroot epidemiology and improved durability of host resistance. This research aimed...

The Impact of Clubroot Resistant Canola Cultivars on Plasmodiophora brassicae Resting Spore Concentrations in the Soil
DownloadFall 2016
The soilborne pathogen Plasmodiophora brassicae Woronin, causal agent of clubroot of canola (Brassica napus L.), is difficult to manage due to the longevity of its resting spores, its ability to produce large amounts of inoculum, and the prohibitive costs of effective fungicides. The cropping of...
