Clubroot—Plasmodiophora brassicae
During initial stages of clubroot, aboveground symptoms may be absent. Foliar symptoms include stunting,
yellowing, wilting, and other signs of a dysfunctional root system. Extensive galling, swelling, and distortion
of the roots and hypocotyl are the main symptoms of the disease.

Solutions
Clubroot is most common in acid soils. Add lime annually to affected soils below pH 7.2. Minimize the
spread of the pathogen by using pathogen-free transplants. Rotate out of crucifer crops for at least 2
years. Solarization will also give control.
