Abiotic and biotic factors influencing host-plant use of a generalist herbivore through plant-mediated interactions: oviposition and larval performance by the bertha armyworm, Mamestra configurata Walker (Lepidoptera: Noctuidae) on canolaDownload
The bertha armyworm (BAW), Mamestra configurata Walker (Lepidoptera: Noctuidae), is a native, polyphagous herbivore which feeds on a variety of plants in different families. In the Prairie Provinces, canola, Brassica napus L. (Brassicaceae), is a preferred host, making BAW a significant pest....
An assessment of the fumigant metam sodium and a Brassica juncea-derived biofumigant as management tools for clubroot (Plasmodiophora brassicae) of canola (Brassica napus)Download
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)Download
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,...
Pathotypes of Plasmodiophora brassicae from clubroot resistant canola and assessment of amisulbrom for clubroot controlDownload
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....
Progress towards the sustainable risk management of clubroot (Plasmodiophora brassicae) of canola on the Canadian prairiesDownload
Clubroot, caused by the obligate parasite Plasmodiophora brassicae Woronin, has recently emerged as an important disease of canola (Brassica napus) in central Alberta. Disease development is characterized by the formation of large galls on the roots of affected plants, which hinder water and...
Spheroidal gall formation and seedborne infestation by Plasmodiophora brassicae as overlooked aspects of clubroot biology and epidemiologyDownload
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....
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...
