Watching brief for potential impact on tomato production in the Mediterranean. Other southern European countries likely to be more at risk. Precautionary action will be taken on findings on planting material to protect glasshouse crops and botanical gardens.
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.
