Fight Against Blight

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. The information is collected on a voluntary basis by our team of Blight Scouts drawn from members of the industry who are routinely walking potato fields during the season.
