Tomato potato psyllid (TPP)

The Department of Primary Industries and Regional Development is working with the State’s horticulture industry to combat tomato potato psyllid (TPP), following a national decision that it is not technically feasible to be eradicated.

The damaging insect pest was detected in Western Australia for the first time in February 2017, prompting a national biosecurity response.  It has not previously been found in Australia.

TPP attacks a range of vegetable crops in the Solanaceae family including tomato, eggplant, capsicum, chilli, tamarillo and sweet potato.

A Quarantine Area Notice in Western Australia remains in place for the Perth metropolitan area and surrounds to help prevent the spread of the psyllid.

Spring surveillance boost to combat horticulture pest

Trapping for TPP will ramp up later this spring with the warmer weather conducive to increased insect activity.

WA commercial vegetable growers and backyard gardeners are asked to assist the survelliance program by hosting 'sticky traps' on their properties with host plant material.

The department has had great support from landholders in supporting TPP response activities since the pest was first detected in WA, with surveillance across more than 1600 properties and the deployment of more than 10 000 traps.

National agreement on TPP management plan

National agreement has been reached on a management plan for the tomato potato psyllid (TPP) by federal and state governments, and the horticulture industry.

The Transition to Management Plan will improve the capacity of the horticulture sector to manage TPP, and build confidence around the status of the bacterium Candidatus Liberibacter solanacearum (CLso) associated with the psyllid.

Development of the Transition to Management Plan follows the National Management Group decision earlier this year that TPP is not technically feasible to eradicate, and efforts should focus on effective management.

The pysllid has had a significant impact on Western Australian growers, limiting interstate trade for a range of host or carrier plants and produce.

There have been no detections of CLso in Western Australia to date.

The plan outlines the following major activities:

  • targeted surveillance for TPP/CLso complex during Spring 2017 and Autumn 2018
  • scientific research to improve understanding of TPP, its biology and options for control.
  • management of TPP through the development of national and enterprise management plans
  • market access and trade.

Other states will also implement surveillance plans for the pest.

The department will lead research work including examining chemical control options, post-harvest disinfestation trials and assessing biological control options using predator species.
