Details on the situation of Phytophthora ramorum in United Kingdom
The current situation of Phytophthora ramorum (EPPO Alert List) in United Kingdom can be viewed on the web site of the Department for Environment Food and Rural Affairs (DEFRA). As a result of intensive surveys, P. ramorum has now been found at 290 sites in England and Wales, as well as some 30 sites in Scotland, Northern Ireland, Jersey and Guernsey. Most findings were made in commercial nurseries and garden centres on plants in containers, but in a few cases, infections were found on plants growing in the soil. P. ramorum has mainly been found on Rhododendron and Viburnum, but also on Pieris, Camellia, Syringa, and Kalmia. The pathogen has been detected once on pot-grown Taxus baccata (yew), as well as on a plant of Hamamelis virginiana grown in a public garden in Wales near infected Rhododendrons. Eradication and containment measures are taken whenever the pathogen is found, and they include: destruction of affected plants, tracing of related stocks and restrictions on the movements of other susceptible plants.
