This report highlights the urgent need for global action to reduce the spread of Xylella Fastidiosa, a plant pest of international concern. The disease poses a significant threat to a wide range of plant species and industries. The role of the International Plant Protection Convention (IPPC) and Regional Plant Protection Organizations (RPPOs) in facilitating global action is emphasized.

  2. Pest on International Concern(Xylella fastidiosa) • Australia is working to broaden and strengthen quarantine measures to safeguard against entry of Xylellafastidiosa (Xf) because: • There are a number of subspecies of the bacterium, which are spreading around the world

  3. Xylella fastidoisa • The host range of these subspecies is extensive (200+) and increasing almost daily • With the recent detections in France and Italy we think it is inevitable that the disease will continue to spread within Europe – it will be very difficult to eradicate it • Vectors are widespread

  4. Xylella fastidiosa • Some hosts are symptomless and many are traded internationally as nursery stock • The disease poses a significant threat to the large number of susceptible plant species including horticultural industries such as almond, blueberry, cherry, citrus, coffee, grape, olive, peach and plum, forestry and amenity trees. It also infects some grasses.

  5. Role of IPPC • Given the potential significant and global threat that is posed by the spread of Xylella, it would be very useful for the IPPC to step up and facilitate global action to reduce the spread of the disease. • The IPPC did get involved in the risk alert and some responses to the threat of wheat stem rust (UG99) some years ago.

  6. Role of IPPC • This could be by: • Issuing a global alert - immediately • Reporting spread • Establishing an expert advisory committee to assist CPs with risk assessment (there is a recent one out of Europe), changes in host status, surveillance, diagnostics, phytosanitary risk measures and management

  7. Role of IPPC • Providing useful resource materials/references to assist CPs reduce the risk of spread and disease impact

  8. RPPOs • RPPOs - asked to support PPPOs suggestion • RPPOs might also consider the role that they could play in assisting their members in protecting themselves from this threat
