A team of researchers at the University of Warwick is working on a new approach to detect Fusarium basal rot (FBR), a disease that causes over 50% yield losses in onion crops. The project, funded by Innovate UK and Defra’s Farming Innovation Programme and led by the British Onions Producer Association, involves the development of a DNA-based soil test to identify high-risk fields and scent-based indicators to detect infected onions. The aim is to transform onion farming, ensure its sustainability, and reduce crop losses through rapid decision making.
