Recommended regulated non-quarantine pests: Towards a wider and better application of the international concept in the EPPO region

Abstract

Description of the subject. Measures against regulated non-quarantine pests (RNQPs) aim to prevent an unacceptable economic impact on the intended use of plants for planting by pests that are already present in the area. Therefore unlike quarantine pests, the likelihood of introduction of RNQPs is not a relevant criterion. Although the term RNQP was introduced in the FAO International Plant Protection Convention (IPPC) in 1997, to date, very few countries in the EPPO region have used the RNQP concept explicitly. However, in December 2016, the European Union introduced RNQPs in EU Regulation 2016/2031 on protective measures against pests of plants, in line with international standards, to be implemented by December 2019. Objectives. EPPO undertook a 2-year project, funded by the European Commission, to develop a methodology to assess whether pests should be RNQPs and apply this methodology to pest/host/intended use combinations obtained from Council Directive 2000/29/EC and EU Marketing Directives on reproductive material. Method. A methodology allowing a quick risk analysis was developed. Results. This methodology was applied to approximately 1,400 pest/host/intended use combinations within different sector expert working groups, including 44 combinations for the seed potato (i.e. potato plants for planting) sector. When applied to blackleg disease on seed potatoes, experts recommended the listing of the genera Dickeya and Pectobacterium as RNQPs for the EU and the EPPO region. Conclusions. This project has produced a harmonized evaluation process and recommendations by experts for several pest/host/intended use combinations (as Dickeya spp. and Pectobacterium spp. for seed potatoes) for regulation as RNQPs throughout the EPPO region. EPPO is now considering whether to endorse these recommendations.
