Cereal Rusts & Powdery Mildews Conference 2022
Welcome to the 16th International Cereal Rusts and Powdery Mildews Conference 2022
Clare College, Cambridge, UK
31 August - 2 September 2022
Thank you to everyone who attended ICRPMC 2022.
ICRPMC 2022 was organised by NIAB on behalf of the European and Mediterranean Cereal Rust Foundation (EMCRF). Its mission was to promote and disseminate the latest scientific advances in research on cereal rusts and powdery mildews, and facilitate discussions and collaboration towards globally sustainable cereal disease management.
