Crop rotation, cultivar resistance, and fungicides/biofungicides for managing clubroot (Plasmodiophora brassicae) on canola

摘要: AbstractSelect biofungicides and fungicides, used alone or with cultivar resistance crop rotation, were assessed for their potential in integrated management of clubroot disease. The synthetic fungicides pentachloronitrobenzene, fluazinam cyazofamid showed activities against Plasmodiophora brassicae. Serenade® Prestop® also suppressed the disease on canola via antibiosis induced host under controlled-environment conditions. Granular seed-treatment formulations developed to facilitate delivery biofungicide field trials. Where P. brassicae resting spore populations large soil, neither nor sufficiently effective when applied seed furrow. They occasionally reduced severity Chinese cabbage. More than 5000 soil microbial isolates indigenous Canadian prairies screened control, but none consistent efficacy. Resistant cultivars clubr...
