Pests recently added to the EPPO A1/A2 Lists or of urgent phytosanitary concern 

- Last updated in 2021-09 -

 

 

In order to help its member countries, the EPPO Secretariat has listed below the pests which have recently been added to the EPPO A1/A2 Lists (during the last 5 years, i.e. since 2015) or which are currently presenting a particular risk for the EPPO region. The aim is also to encourage countries or areas at risk to consider taking phytosanitary measures. Recommended phytosanitary measures can be found in PRA reports (see EPPO Platform on PRAs)  .
