Clubroot is a soil borne disease that swells and distorts cole crop roots into club shapes, so plants wilt in the day, stay stunted and yield poorly, and it is worse in acidic, wet soils. The pathogen survives many years in soil, so the main tools are long crop rotation away from cole crops, raising soil pH with lime towards neutral, and improving drainage. Use clean seedlings from disease free nursery soil and remove and destroy affected roots rather than leaving them in the field. Resistant varieties are available in some areas. Confirm lime quantity from a soil test and Soil Health Card, and discuss a rotation plan with your hill KVK before replanting cole crops.

In the Nainital hills my cauliflower roots came up swollen and club shaped and the plants stayed stunted. A soil test showed low pH, and liming towards neutral with better drainage slowly improved that field.

A point from my experience: this thing stays in the soil for years. Short rotation did nothing, only a long break from cole crops plus clean nursery soil gave me a decent crop again.

A tip: I get my seedlings from clean nursery soil, not from the affected field, and remove and destroy the clubbed roots after harvest. Leaving the galls in the soil only feeds the problem for years.

I got my soil tested before liming rather than guessing the dose. The Soil Health Card showed how acidic that field was, and bringing the pH up towards neutral with the right amount of lime, along with better drainage, was what finally let me grow cole crops there again.
