Blight Report & Incident Summary

Late blight, caused by the pathogen Phytophthora Infestans, remains the single most important disease for the British potato trade. Spreading quickly in the foliage, a typical blight pressure season can cost the industry approximately £55 million a year in a business as usual scenario. With such a significant impact on the industry, it’s important to respond quickly and raise awareness of the risk associated with its changing strains.

As a part of the research into blight populations, the AHDB Potatoes Fight against Blight service has been reporting blight alerts for the past 10 years.
