Phytoplasma present in Australia and New Zealand which could be damaging to grapevine and strawberry production; in particular; if introduced to the UK. EU regulations help to mitigate the risk of entry.
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.
