Clubroot, caused by Plasmodiophora brassicae, presents a significant threat to Brassica crops, affecting an estimated 10% of the global cultivated area. Syngenta has dedicated years to breeding in order to provide highly resistant Brassica varieties.

Symptoms of Clubroot
This soil-borne fungal disease targets the roots of Brassica crops and is recognized as one of the most economically impactful diseases for cultivated crucifers. Affected roots become swollen and distorted, leading to stunted growth and, in most cases, reduced yield. The pathogen can persist in the soil for up to 15 years in the form of resting spores released from decayed galls.

Syngenta's Approach
Cultural practices offer limited potential to mitigate crop losses due to clubroot, and chemical treatments for fungus control are either prohibited due to environmental regulations or are not cost-effective. The most effective strategy to combat clubroot is through the development of resistant varieties. After years of breeding efforts, Syngenta has successfully introduced a high level of resistance in Cauliflower varieties.
