From 8 December 2025, Victorian businesses sending nursery stock interstate need to meet the import conditions set by the destination state/territory for Tomato Potato Psyllid (TPP). These conditions vary depending on whether the consignment is a TPP host or a TPP “carrier”. Agriculture Victoria

​

What is TPP and why does it matter?

TPP (Bactericera cockerelli) is a small sap-feeding insect that attacks plants in the Solanaceae family (including tomato, potato, capsicum/chilli and eggplant). It can also settle on non-host plants, which are treated as “carriers” for biosecurity purposes. Agriculture Victoria+1

TPP was first detected in Victoria in November 2024 (Bellarine Peninsula) and later detected again in October 2025 in Melbourne’s northern suburbs, which has triggered tighter interstate movement requirements. Agriculture Victoria+1

​

What is ICA-62?

ICA-62 is an Interstate Certification Assurance pathway (released 7 November 2025) that allows accredited nurseries to self-certify eligible TPP carrier nursery stock for certain interstate markets. While accreditation could be obtained earlier, the requirement to operate under it takes effect from 8 December 2025. Agriculture Victoria

​

What ICA-62 generally requires (in plain English)

While requirements can differ by destination, ICA-62 is built around a simple risk-reduction approach:

• Treatment timing: Stock is treated within 72 hours before dispatch. Agriculture Victoria+1

• Inspection: Inspection occurs after treatment to confirm the treatment worked. Agriculture Victoria

• Sampling: The inspection rate is 2% of the consignment or 600 plants (whichever is greater) — small consignments may require inspection of all plants. Agriculture Victoria

• Secure packing/transport: Stock must be packed and transported in a way that prevents reinfestation during freight. Agriculture Victoria+1
