A bacterial disease with a wide host range and many sub-species and strains; including those that could thrive in cooler climates; showing different levels of pathogenicity. Although EU regulated; there is some concern about the risk of introduction. Should an outbreak occur; there would be a need for eradication action which would result in environmental and social impacts.

About this section

Our plants are under greater threat than ever before. There is increasing movement of plants and other material traded from an increasing variety of sources. This increases the chances of exotic pests arriving with imported goods and travellers, as well as by natural means. Shoot is working with Defra to help members to do their part in preventing the introduction and spread of invasive risks.
