High Risk Plants – RHS Shows Last Revision: March 2019 Executive Summary New pests and diseases of plants (collectively referred to as pests) are introduced to the UK every year. Import and movement of plants for planting is a major pathway for the introduction and spread of these pests. In order to combat this, there are official regulations on movement of plants which depend on their species and origin. This document is intended to provide guidance to both exhibitors at RHS shows and to shows staff on plant health regulations and RHS plant health policy. It is intended to provide guidance on plants that represent a significant risk to UK plant health because of the pests that may be associated with them. Although it will be updated as new information becomes available it cannot provide an exhaustive list of all risks. The document does not provide guidance on plants that are pests in their own right due to their invasiveness, and whose movement is regulated by legislation, e.g. plants listed in Schedule 9 of the Wildlife and Countryside Act (1981) or in Commission Implementing Regulation 2017/1263. A list of plants on Schedule 9 of the Wildlife & Countryside Act (1981) is available here, and those controlled by Commission Implementing Regulation 2017/1263 are detailed here. This document provides guidance on import regulations but is NOT an exhaustive list of all requirements on imported plants. Plant health regulations are updated regularly. If you are sourcing plants from abroad for RHS shows, you should always check the latest plant health requirements with the APHA. Call the Plant Health Helpline on 01904 405 138 or email: [email protected] In terms of official regulations, plants are either prohibited (cannot be imported or moved), controlled (must be accompanied by official documentation) or uncontrolled (can be moved freely). The RHS have introduced additional policies on plants used at shows to provide additional protections and ensure all shows have a high plant health status. 1 Certain hosts of Xylella fastidiosa, a major bacterial disease causing devastating outbreaks in Europe, are prohibited from use at RHS shows unless they are UK sourced and grown. This is defined as those having been propagated from seed in the UK or having been grown in the UK for a minimum of 12 months preceding their use in an RHS Show. The hosts are: Coffea spp. (coffee) Hebe spp. (hebe) Lavandula spp. (lavender) Nerium oleander (oleander) Olea europaea (olive) Polygala myrtifolia (polygala) Prunus spp. (cherry, plum etc.) Rosmarinus officinalis (rosemary) Spartium junceum (Spanish broom) The RHS also has additional requirements on the use of semi-mature trees at shows. These trees are defined as those that are over 5 metres in height OR have a circumference of 20 cm. Semi-mature trees used at shows must: 1. Sourced and grown in the UK. (This is defined as those having been propagated from seed in the UK OR having been grown in the UK for a minimum of 12 months preceding their use in an RHS Show.) OR 2. If imported, held and monitored in the UK for at least 3 months prior to use in an RHS Shows. The RHS plant health team will carry out spot checks on exhibitors and gardens to ensure they are complying with RHS policy. You are strongly encouraged to keep all documentation in association with your plants such as plant passports and delivery notes, so that these can be examined in the event of a spot check. 2 Contents Introduction ........................................................................................................................... 6 How to use this Document .................................................................................................... 6 Section 1.
