Abstract:

The pathogen and symptoms of rapeseed clubroot were introduced, and the occurrence regularity of rapeseed clubroot was expounded from the aspects of pathogenic conditions, infection process and infection cycle. The cause factors of rapeseed clubroot were introduced, including the lack of resistant (tolerant) varieties, continuous cropping and accumulation of inoculum, serious soil acidification, suitable meteorological conditions for disease occurrence and rough management. The agricultural control measures of rapeseed clubroot were introduced, such as the selection of resistant varieties, reasonable fertilization, improvement of acidic soil, regular rotation, strengthening bed disinfection and field drainage management. The application of several biocontrol bacteria or fungi in the biological control of rapeseed clubroot was reviewed. The main chemical control measures were summarized from the aspects of indoor agent screening, seed coating, seedbed treatment, and root dipping irrigation. In summary, on the basis of the above agricultural control measures, biological control, chemical control and other methods should be comprehensively utilized to achieve comprehensive prevention and control of rapeseed clubroot and ensure the sustainable development of China’s oil industry.

Key words: rapeseed clubroot, Plasmodiophora brassicae, disease symptom, Brassica napus, soil-borne disease, epidemic regulation, comprehensive prevention and control
