Established pest of a widely grown ornamental in the UK. Potential for economic and social impacts unless resistant varieties are developed. Statutory action unlikely to prevent further spread.
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.
