Summary of the information used for the evaluation	Possibility that the pest could become associated with the commodity Phytophthora ramorum is present in the UK with a restricted distribution. The pathogen has a wide host range including Fagus sylvatica. The main hosts (e.g. Rhododendron spp., Larix spp., Viburnum spp. etc.) can be present either inside or in the surroundings of the nurseries. Aerial inoculum could be produced on these host plants and cause bark infections on the commodity. Measures taken against the pest and their efficacy P. ramorum is a quarantine pest in the UK and under official control. General measures taken by the nurseries are effective against the pathogen. These measures include (a) the use of certified plant material and growing media; (b) inspections, surveillance, monitoring, sampling and laboratory testing; and (c) application of pest control products. Interception records In the EUROPHYT/TRACES‐NT database, there are no records of notification of F. sylvatica plants for planting neither from the UK nor from other countries due to the presence of P. ramorum between the years 1995 and December 2022 (EUROPHYT, online; TRACES‐NT, online). Shortcomings of current measures/procedures None observed. Main uncertainties – The level of susceptibility of F. sylvatica to the pathogen. – Whether symptoms may be promptly detected. – The presence/abundance of the pathogen in the area where the nurseries are located. – Effect of fungicide treatments against the pathogen.

Main uncertainties – The level of susceptibility of F. sylvatica to the pathogen. – Whether symptoms may be promptly detected. – The practicability of inspections of older trees. – The presence/abundance of the pathogen in the area where the nurseries are located. – Effect of fungicide treatments against the pathogen. – Whether and to which extent plants transplanted to the pots before export have undergone a cleaning of roots.
