First report of Phytophthora ramorum in United Kingdom
In April 2002, during a routine monitoring visit to a nursery in West Sussex, England (GB), a group of 10 Viburnum plants showed dieback. A sample was taken and the presence of Phytophthora ramorum (EPPO Alert List) was detected. Since then, a total of 11 findings were made at premises in England (West Sussex, Lincolnshire, Dorset, Lancashire, Hampshire, Shropshire and Worcestershire). 10 findings were made on Viburnum and 1 on Rhododendron. All affected plants have been destroyed, and there is no evidence that P. ramorum has spread from the infected plants. Investigations currently made did not reveal any consistent pattern in the origin of the affected material. In addition, there has been one finding in Scotland and one in Guernsey. Measures are taken to restrict imports of plants which can carry the fungus from areas in USA where it occurs, and within UK movement of plants of Viburnum and Rhododendron must be notified to the NPPO. The situation of P. ramorum in United Kingdom can be described as follows: Present, found on Viburnum and Rhododendron in a few nurseries, under official control.
