Upcoming changes in nursery stock hosts requiring emergency measures for Xylella

Effective from 10 July 2020

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

These actions are being carried out under Australia’s emergency measures for Xylella and will commence on 3 August 2020. 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 also notify trading partners of this change through a Sanitary and Phytosanitary (SPS) notification.

What will change:

  1. Regulatory measures will apply to more plant families.

    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 nine (9) additional plant families.

    These families are:

    • Cannaceae

    • Gesneriaceae

    • Linaceae

    • Polemoniaceae

    • Resedaceae

    • Scrophulariaceae

    • Simmondsiaceae

    • Strelitziaceae

    • Tamaricaceae

    This change affects 59 genera within BICON; see Table 1 for a list of affected genera. These additional families will increase the total number of regulated plant families from 89 families to 98 families.

    An overview of import conditions that would need to be met for plant propagative material (excluding seeds) are outlined within the department’s website.

  2. Genera within existing regulated plant families are being updated

    Since emergency measures were introduced in 2015, the department continues to review the application of existing conditions to ensure that they are fit-for-purpose and effective in managing biosecurity risks. Import conditions are being revised to ensure that emergency measures are appropriately targeted to the original list of 89 regulated plant families. These changes will result in:

    2.1. Thirty-nine (39) genera requiring additional measures for Xylella (Table 1).

    2.2. Seventeen (17) genera no longer requiring regulatory measures for Xylella, as they do not belong to a regulated plant family (Table 2).

What types of material are affected:

These changes affect all permitted genera and species within affected plant families, imported as nursery stock. This includes tissue cultures, rooted plants, budwood and cuttings.

These requirements do not apply to imports of true botanical seeds.

What about consignments that are in-transit:

The revised conditions will apply to consignments that are exported to Australia on or after 3 August 2020.

  • Consignments that are exported to Australia prior to 3 August 2020 will be permitted entry into Australian territory under existing conditions.

  • Commercial documentation (i.e. bill of lading or airway bill) must be provided to the department to verify that the date of export was prior to 3 August 2020. Consignments that are unable to meet this requirement will be subject to the revised conditions.

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.

As we transition to the revised measures, there will be delays to the issuance of new import permits for affected genera. However, we will work with permit applicants to minimise trade impacts as much as practically possible. Permit applicants will be required to provide information on their import plans to assist with this process.

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 to broaden and 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.
