Which of the following is a method to manage Clubroot?

Destroying infected roots is a key management method for Clubroot, a serious disease caused by the soil-borne pathogen Plasmodiophora brassicae, which affects members of the Brassicaceae family, including crops like cabbage and canola. By removing and destroying infected plants, you significantly reduce the amount of pathogen present in the soil, thus limiting its ability to spread and affect future crops.

This practice is particularly effective because the pathogen can persist in the soil for several years as resting spores, even in the absence of suitable host plants. By proactively removing infected roots, you eliminate a source of these spores, thereby reducing the overall disease pressure in the field.

Proper disposal of infected plant material can also prevent the pathogen from being spread through contaminated tools, equipment, or even through water. This focus on hygiene and the destruction of the disease reservoir is essential for effective Clubroot management.
