Bacterial pest affecting citrus and field vegetables now present in parts of the EU. Carrots are the main crop potentially at risk; but main vectors responsible for transmission are unlikely to establish in the UK. EU regulations should be updated to reflect extended host range. Industry may be interested in pursuing research to investigate impacts on field vegetables.

Pest mainly associated with Citrus in South Africa; occasionally intercepted with cut flowers. EU listing should be updated to reflect interception findings.
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.
