ENLARGED OR DEFORMED ROOTS.
Cause: Club root (Plasmodiophora brassicae), a fungal-like disease.
Treatment: Rotate crops annually, avoid planting sites where other cole crops were grown in the previous year. Club root outbreaks are worse in wet and acidic soils. In low pH soils, the addition of lime may be helpful. Approved fungicides may be available. Contact your chemical supplier or local Extension agent for the latest fungicide recommendations.
