Biosecurity alert: Tomato potato psyllid

The Department of Agriculture and Food, WA is working with the WA horticulture industry to respond to the detection of tomato potato psyllid, an exotic plant pest.

This is the first time the psyllid has been detected in Australia.

Tomato potato psyllid attacks a range of plants including potato, tomato, eggplant, capsicum, chilli, tamarillo, sweet potato and goji berry. It is a significant production pest.

The psyllid has been confirmed mainly in the Perth metropolitan area in commercial and residential properties, and retail outlets. There have also been detections in regional areas.

Ongoing surveillance

The Department of Agriculture and Food, Western Australia (DAFWA) has installed hundreds of traps across regional and metropolitan areas on commercial and residential properties. Traps are checked regularly.

Metropolitan growers

Due to the large number of metropolitan infestations, we are no longer asking residents, including home and community gardeners to report suspect detections. Instead, undertake control in your gardens in accordance with the options provided by DAFWA.

Residential growers can access a list of approved chemicals and eco-friendly oils from this page

A community alert flyer to distribute and display at metropolitan retail outlets can also be downloaded from this page.

Commercial growers need to be aware of requirements for movement of produce into regional areas of Western Australia (see Quarantine Area Notice and map below).

Regional growers

DAFWA is urging regional growers including home and community gardeners to continue surveillance for the pest. See the video below on how to check your garden.

Report any suspect sign of the psyllid immediately to DAFWA through the MyPestGuide Reporter app. Do not undertake any treatment or control.

A community alert flyer to distribute and display at regional retail outlets can be downloaded from this page.

You can also report findings to DAFWA via web, phone or email:

Quarantine Area Notice and map

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 pest.

A new QAN is in effect, which divides Western Australia into three quarantine zones - a Control (red) Zone, Suppression (orange) Zone and Watch (blue) Zone. The new QAN can be downloaded from this page.

Frequently Asked Questions for commercial growers can also be downloaded from this page. More information for backyard growers and the community is available.

The revised measures aim to provide a more 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 Control Zone covers the metropolitan area, 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.

The 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.


See the map below to determine which zone you are in.
