Funded by AHDB and APHA, and managed by NIAB in Cambridge, the UK Cereal Pathogen Virulence Survey (UKCPVS) has been monitoring cereal rusts and mildews in the UK for more than 50 years. It provides an early warning system to growers and plant breeders of new races of disease that could overcome current variety resistance, and underpins the AHDB Recommended List disease resistance ratings. NIAB pathology lead Dr Lucy James summarises the latest work and advice from UKCPVS.
