What is the common name for the pathogen Plasmodiophora brassicae?

The pathogen Plasmodiophora brassicae is commonly known as Clubroot. This soil-borne pathogen affects plants in the Brassicaceae family, including crops such as cabbage, broccoli, and cauliflower. Clubroot causes significant root distortion and swelling, leading to poor nutrient uptake and ultimately stunted plant growth or even plant death. The characteristic galls or clubs formed on the roots are a key indicator of infection, thus giving rise to the common name "Clubroot."

This disease is a major concern in agricultural settings where brassica crops are cultivated, particularly in cooler, moist conditions that favor the pathogen's development and spread. Understanding the common name helps in identifying and managing this specific disease in crops, which is essential for effective disease control and crop management strategies.
