In October 2025, Tomato-Potato Psyllid (TPP) was found in Melbourne’s northern suburbs, following an earlier detection on the Bellarine Peninsula in 2024.

From 8 December, all Victorian businesses transporting TPP host or carrier plants or produce interstate will need to comply with entry requirements set by each destination jurisdiction. These requirements vary by state and differ for host and carrier commodities of TPP.

Agriculture Victoria is implementing accreditation arrangements to facilitate interstate trade of host or carrier plants or produce.

The latest Biosecurity Update from Agriculture Victoria is available here.

If you send produce interstate, please prioritise the application for accreditation.

To register for accreditation, you can fill in forms PSF-001 and PSF-260 and send them to biosecurityservicescentre@agriculture.vic.gov.au

Key points for Victorian growers

• It is important that you apply for accreditation as soon as possible.
•  If you grow host or carrier produce in Victoria and move it interstate your business will need to comply with destination jurisdiction entry requirements for Tomato potato psyllid (see links below). A summary of conditions for importation of fruit/vegetables with green material into other jurisdictions is also available in the tables at the end of this Biosecurity Update from Agriculture Victoria.
• Agriculture Victoria is implementing a certification system to facilitate movement of produce to other states and territories.
• The accreditation allows vegetable businesses to self-certify TPP carrier produce for interstate exports as an alternative to getting a Plant Health Certificate issued by an Agriculture Victoria authorised officer.
• Carrier produce means any produce that has green plant material attached (e.g. calyx, leaves). The definition excludes produce from the Convolvulaceae and Solanaceae family of plants (these are TPP host produce often referred to as TPP true hosts).

If you plan to move host or carrier plants or produce, you must be accredited by 8 December.

• Different states may have different requirements; please check the websites below for requirements for the state to which you are moving product.
• Watch the Agriculture Victoria Webinar from 27 November here.

TPP Carrier Produce – next steps

Agriculture Victoria has developed Interstate Certification Assurance (ICA-61) to describe the requirements that apply to packhouse washing, inspection and secure consignment of TPP carrier produce with leaves, calyx or other attached green material under an ICA arrangement.

Consignments originating from Victoria may be subject to inspection, treatment and certification requirements by destination states.

Apply for accreditation for your business to self-certify TPP carrier produce

1. Register for self-accreditation and training by referring to and completing the forms and documentation linked below, or request these from the Agriculture Victoria’s Biosecurity Services Centre at: biosecurityservicescentre@agriculture.vic.gov.au.
2. Once your application is processed you will receive links to the required e-Learning modules. The e-Learning modules and assessments replace the usual face-to-face initial audit which enables streamlining of the accreditation process.
3. You will be issued with a Certificate of Accreditation after successfully completing these modules and assessments. Please note that the assessment must be passed to receive accreditation. The assessment is challenging to maintain rigour in the process, and successful completion of the assessment.
4. Your business will be able to self-certify once their Certificate of Accreditation has been received.
5. Requirements come into effect on Monday 8 December 2025.
6. Check the websites below for the destination state for your produce to make sure you meet the requirements for that state.

Agriculture Victoria advises the process for business accreditation will take approximately five working days after submitting a completed application. Agriculture Victoria will be in contact if they have any questions.

Important: the definition of green material may differ across jurisdictions; please consult the relevant website below for requirements of the destination jurisdiction.

Next steps for TPP host produce not covered by ICA-61

TPP host produce is not covered by ICA-61 and will need to be consigned under another approved protocol. Market access requirements for true hosts (e.g. capsicum, eggplant, tomato) are currently being negotiated with other states under two agreements: PS-57 Nursery stock and PS-58 Host Produce.

Both will be released next week. Both protocols require treatment for all life stages of TPP, inspection and secure packaging.

More information on host produce arrangements is expected this week. Following a 2 November webinar on host produce and host nursery stock, a further webinar for the fruit industry (including capsicum, eggplant and tomato growers) will be held on Wednesday 3 December. You can register for that here.

About Tomato potato psyllid

Tomato potato psyllid (Bactericera cockerelli) is a tiny sap-sucking insect that affects potatoes, tomatoes, capsicum and other Solanaceous crops and weeds causing minor damage through feeding on host plants.

More significantly, TPP can transmit Candidatus Liberibacter solanacearum (CLso), the organism responsible for Zebra chip disease—a significant threat particularly to potato production. CLso has not been detected in Australia and all TPP collected in Victoria so far have tested negative to the pathogen.

If you suspect TPP, report it to the Exotic Plant Pest Hotline: 1800 084 881

AUSVEG will continue to provide further updates as they become available.
