Rust fungus affecting blueberry and hemlock. This fungus has been detected in Europe (Germany; Netherlands and Portugal). Some uncertainty about the suitability of UK native host species. But the case for regulation should be considered based on the EPPO PRA.

General biosecurity comments

Polyphagous moth pest which defoliates deciduous trees and; with repeated infestation; can cause tree death. Present in North America and current import requirements do not fully mitigate the risk of introduction. A PRA will help to assess the level of risk more fully.

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.
