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 canola
DownloadFall 2018
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....

Comparative transcriptome analysis of rutabaga (Brassica napus) cultivars in response to Plasmodiophora brassicae
DownloadFall 2020
Clubroot, a soil-borne disease caused by the obligate parasite Plasmodiophora brassicae Woronin, is a threat to canola (Brassica napus L.) production in western Canada. Genetic resistance represents the most effective tool to manage this disease. To improve understanding of the mechanisms of...

Keddie, B. A., Sarfraz, R. M., Tansey, J. A., Dosdall, L. M.
Abstract: Insecticidal seed treatments are used commonly throughout the Northern Great Plains of North America to systemically protect seedlings of canola (Brassica napus L. and Brassica rapa L.) from attack by the flea beetles Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (F.)...

Given the roles of roots in water and nutrient uptake, anchorage, and storage of resources, root system architecture (RSA) can have a major impact on plant growth and development. The root systems of Brassica species, an important group that includes many field and horticultural crops, is...

Clubroot (Plasmodiophora brassicae) is a serious soilborne disease of canola (Brassica napus), negatively affecting the Canadian agricultural sector. Since clubroot development is favored in acidic soils, the application of lime to increase soil pH to ≥ 7.2 is recommended as a disease management...

Fall 2021
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,...
