Quarantine area information

A Quarantine Area Notice (QAN) is in place to direct the movement and treatment of specified commercially-produced fruit, vegetables and seedlings to contain and control the tomato potato psyllid (TPP). The QAN can be downloaded from this page.

Quarantine Area Notice (QAN)

The measures aim to provide a consistent approach for all producers in the metropolitan area and surrounds, where the psyllid is present, and strengthen efforts to limit its spread into regional areas.

The Quarantine control zone covers the entire Perth metropolitan area and surrounds, which includes the shires of Wanneroo in the north and Serpentine-Jarrahdale in the south and Mundaring in the east, as well as the City of Mandurah and the shires of Gingin, Chittering and Murray.

A bordering suppression zone includes the shires of August-Margaret River, Beverley, Boddington, Boyup Brook, Bridgetown-Greenbushes, Brookton, Capel, Collie, Dandaragan, Dardanup, Donnybrook-Balingup, Harvey, Manjimup, Moora, Nannup, Northam, Toodyay, Victoria Plains and Wandering, and the cities of Bunbury and Busselton.


Information for industry

The QAN applies to commercial and home-grown host fruit, vegetables and nursery stock grown within the Quarantine Area.

Movement restrictions also apply to any machinery, equipment, soil or other plant growing medium used in connection with host plants.

Restrictions vary for each zone. Refer to the Quarantine Area map to determine which zone you are located in.

These changes are in line with a national response plan which includes containment measures for TPP and increased testing and monitoring for the bacterium Candidatus liberibacter solanacearum (CLso).

This will be coupled with ongoing surveillance and monitoring by the department for the pest and CLso.

Quarantine zones and movement restrictions for commercial growers

The control zone (red) requires testing for CLso and a three-step chemical treatment for host plants. There are requirements for treatment of host fruit moving outside of the control zone.

A suppression zone (orange) adjacent to the Ccntrol zone extends from Augusta-Margaret River in the south to Dandaragan in the north and to Brookton in the east. This zone also requires testing and treatment for some plants and produce moving into regional areas.

The watch zone (blue) for the remainder of the State involves ongoing surveillance and mandatory reporting where the pest is suspected.

For more information refer to the latest industry update, which is distributed by the department to keep commercial growers and industry informed of the current situation. Please refer to the documents on the right of this page.
