Description: Phytophthora ramorum was found for the first time in Scotland in April 2002 on some Viburnum tinus plants in a nursery. Seventeen more outbreaks were confirmed in the same year, all on plants moving in horticultural trade. Phytosanitary emergency measures to eradicate the disease were taken, such as destruction of infected plants followed by movement restrictions for potential hosts in the affected premises and increased monitoring. These measures proved to be successful. Already in the following year the number of outbreaks declined dramatically to six, followed by five in 2004,three in 2005, and none in 2006. A new outbreak in January 2007 brought the number of outbreak sites up to 22. With the exception of one private garden, the disease occurred only in nurseries and garden centres.
