General biosecurity comments

A pest mainly of Prunus previously intercepted in the UK on wooden packaging imported from China. There have been longstanding outbreaks of the pest in Italy; a source of significant trade in plants for instant landscapes; and also findings in Germany. The UK will press for early EU regulation and consider UK national measures if risk increases.

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.
