TPP Quarantine Area

A Quarantine Area is in place to direct the movement and treatment of host plants to contain and control the Tomato potato psyllid (TPP) in Western Australia.

The current Quarantine Area Notice can be downloaded from this page.

Quarantine Area Notice (QAN)

A new QAN with revised conditions is effective as of 1 November 2017. This replaces the previous QAN which expired on 31 October 2017.

The QAN was developed in consultation with WA’s horticultural industry and applies to commercially-produced and home-grown host plants or nursery stock grown within the Quarantine Area. The new QAN refines and simplifies previous control measures, and aims to minimise the spread of TPP in Western Australia. 

Prescribed treatment is required for host plants, such as seedlings or nursery stock, where they are moving from the Quarantine Area to Specified local government areas in Western Australia. 

The Quarantine Area includes the Perth metropolitan area and a number of local government areas. See the full list in the table below.

The QAN aims to strengthen efforts to limit the spread of TPP in WA.

Commercial treatment guidelines

Movement and treatment conditions apply to TPP host plants produced within the Quarantine Area, and not to host fruit and vegetables, or machinery and equipment.

The guidelines apply to the movement of host plants within the state only.

Pest Exclusion Notices

Following extensive surveillance, a decision was made by the National Management Group that it is not technically feasible to eradicate TPP in Western Australia. As a result, Pest Exclusion Notices are no longer issued for detection of TPP on properties within the Quarantine Area.

As of 1 November 2017, a Quarantine Area Notice is in place which requires TPP host plants originating from the designated Quarantine Area to be treated in an approved manner prior to being moved to areas outside of the Quarantine Area.

Research by the Department of Primary Industries and Regional Development aims to confirm the efficacy of different chemistry to increase TPP control options available to growers.

The department recommends growers implement a process to ensure product entering their property meets their biosecurity requirements by using a vendor declaration, and continue to ensure good biosecurity processes are in place.
