The European Commission requested the EFSA Panel on Plant Health (PLH) to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as 'High risk plants, plant products and other objects'. This Scientific Opinion covers plant health risks posed by rooted plants in pots of Robinia pseudoacacia 'Frisia' imported from the United Kingdom (UK). The assessment was performed considering the available scientific information, including the technical information provided by the UK. All pests potentially associated with the commodity were evaluated against specific criteria. Two EU-regulated pests (Bemisia tabaci and Phytophthora ramorum non-EU isolates), present in the UK and potentially associated with the commodity, were considered as relevant for this Opinion. No non-regulated pests in the European Union were identified to be selected for further evaluation.
(PLH) et al. (2026) studied this question.
