Awareness needs to be maintained due to the risk of entry as a 'hitchhiker' and monitoring of the pest in countries where it is known to be present.
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.
