Summary of the information used for the evaluation	Possibility that the pest could become associated with the commodity Meloidogyne fallax and M. mali are present in the UK with restricted distribution. Suitable hosts are present both in the nurseries and in the surroundings. Acer palmatum is a host of M. fallax. Acer palmatum and A. pseudoplatanus are hosts of M. mali. Given that both nematodes are highly polyphagous, it is likely that also other Acer species could be used as host plants. The pest can enter into the nurseries and spread within the nurseries with infected plant material and movement of soil attached to machinery and shoes. The plants could become infected during the growth in the soil in the fields. Measures taken against the pest and their efficacy General measures taken by the nurseries are effective against the nematodes. These measures include (a) the use of certified plant material; (b) the use of heat‐treated growing media; (c) inspections, surveillance, monitoring, sampling and laboratory testing; and (d) hygiene measures. Interception records In the EUROPHYT/TRACES‐NT database, there are no records of notification of Acer plants for planting neither from the UK nor from other countries due to the presence of M. fallax between the years 1995 and December 2022 (EUROPHYT/TRACES‐NT, online). In the EUROPHYT/TRACES‐NT database, there are no records of notification of Acer plants for planting neither from the UK nor from other countries due to the presence of M. mali between the years 1995 and December 2022 (EUROPHYT/TRACES‐NT, online). Shortcomings of current measures/procedures Low‐pressure water is used for washing roots before export. This washing may not be as effective as using high‐pressure water in removing the soil, thereby making symptoms less visible. Main uncertainties – Whether symptoms may be promptly detected. – Level of susceptibility of Acer spp. – Pest pressure of the nematodes in the nurseries and in the surrounding areas. – The level to which the low‐pressure water can remove the soil.

Main uncertainties – Whether symptoms may be promptly detected. – Level of susceptibility of Acer spp. – Pest pressure of the nematodes in the nurseries and in the surrounding areas. – The level to which the low‐pressure water can remove the soil of bare‐rooted plants. – Whether plants transplanted to the pots before export have undergone a cleaning of roots allowing the detection of symptoms.
