General biosecurity comments

UK (along with certain other European countries) received potentially infested trees in 1992; but these were destroyed at the end of the trial period and targeted surveillance has failed to find any trace of the nematode. Main impacts are on elm; apple and mulberry and industry should source such material carefully.

General biosecurity comments

A bacterial disease with a wide host range detected in Corsica. Although EU regulated; there remains some concern about the risk of introduction. This subspecies is known to be able to thrive in cooler climates. Should an outbreak occur; there would be a need for eradication action which would result in environmental and social impacts.

About this section

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.
