Alerts

The purpose of this notification is to advise stakeholders that the Department of Agriculture, Fisheries and Forestry (the department) has implemented further actions to manage the risk of the bacterial pathogen Xylella in imported nursery stock.

Effective immediately, regulatory measures to manage the risk of Xylella is now in place for members belonging to the plant family Simaroubaceae

These actions are being carried out under Australia’s emergency measures for Xylella. The emergency measures are in place to safeguard Australia from the entry of Xylella fastidiosa (and all of its sub-species) and X. taiwanensis.

The department will notify trading partners of this change through a Sanitary and Phytosanitary (SPS) notification.

What will change:
The known host range of Xylella is expanding. Under Australia’s emergency measures for Xylella, changes in host status means that measures are required to reduce the likelihood of this pathogen entering Australia.

Due to new published literature showing that Xylella infects new hosts, the emergency measures will be applied to the plant family Simaroubaceae. This change affects the following genera within BICON:

• Eurycoma
• Quassia

Further information on the import conditions that would need to be met for host plant propagative material are outlined within the department’s website.

What types of material are affected:
These changes affect all permitted Eurycoma and Quassia species, imported as nursery stock. This includes tissue cultures, rooted plants and cuttings.

The revised conditions do not apply to imports of true botanical seeds of Eurycoma and Quassia.

How will import permits and new permit applications be affected:
The department will contact affected import permit holders to vary existing permits in line with the above changes. As these permit variations will be initiated by the department, there will be no cost to import permit holders.

Background:
Xylella is Australia's top priority plant pathogen as it has the potential to severely impact our agricultural and horticultural industries and the environment. In addition to having a large host range, Xylella is easily spread by sap-feeding insects and the propagation of infected plants.

Emergency measures for Xylella were implemented in November 2015, and further expanded in August 2020, June 2021, November 2021 and May 2022, to strengthen Australia’s biosecurity requirements that safeguard us against its entry.  The department has commenced a pest risk analysis of Xylella to evaluate these emergency measures and consider ongoing risk management measures to ensure that measures are technically justified.

The department will continue to monitor and assess evidence of new risks posed by Xylella and may amend import conditions again in the future.
