The epidemiology and control of heuchera rust (Puccinia heucherae)

In 2014, AHDB Horticulture funded ADAS and the RHS to undertake a project to improve the understanding of heuchera rust (Puccinia heucherae) and its origin and occurrence in the UK.A key issue for UK growers is where and when in the production cycle does the rust pathogen establish, and this poster details the work undertaken to address this.
