Puccinia coronata avenae, the cause of oat crown rust, is endemic in Britain and occurs most commonly in the warmer southern and south western parts of England and Wales and in particular in Devon, Cornwall, Kent and S. Wales. The fungus appears to overwinter in the uredial stage on autumn-sown crops, on volunteer oat plants and on wild Avena spp. The alternate host, Rhamnus cathartica, although grown as an ornamental shrub, is unimportant in the epidemiology and biology of the fungus, and survival of P.coronatadepends on survival of the oat host.
