Planthopper which can vector the pathogen causing Potato stolbur disease. Present elsewhere in Europe and increasing its range due to a new a nettle-preferring race. Main breeding hosts are not traded as planting material; but some minor hosts (e.g. Lavender) are.
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.
