National agreement on TPP Transition to Management Plan
To read the original Department of Primary Industries & Regional Development email click here.
National agreement has been reached on a Transition to 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.
TPP was found in Western Australia in early February 2017, prompting a large biosecurity response. The pest 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.
What is the TPP Transition to Management Plan?
The TPP Transition to Management Plan aims to manage and limit the impact of the TPP/CLso complex throughout Australia.
The plan continues the TPP response until mid-May 2018, and is led by the Western Australian Department of Primary Industries and Regional Development with support from affected industries, and federal and state governments.
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.
WA transition to management activities
Working closely with WA’s horticulture industry and government partners, the Department of Primary Industries and Regional Development has overall responsibility for rolling out TPP management activities over the next 8 months.
The Department will appoint a project manager to lead the coordination of WA’s TPP management activities, with support from surveillance, entomology and laboratory staff. In addition, the department’s project manager will work closely with the national TPP program coordinator.
The department will be responsible for reporting to the national Consultative Committee on Emergency Plant Pests (CCEPP) on the implementation of the plan.
- Surveillance for TPP will ramp up during spring 2017 autumn 2018, as insect activity is expected to peak during this seasonal
- Surveillance will target metropolitan and regional areas where TPP populations are known to
- Surveillance activities include installing ‘sticky traps’ on commercial and non- commercial properties with host material, including production crops and/or weeds.
- Support for surveillance activities by WA growers has been
- The department’s TPP surveillance team will be in contact with growers to arrange placement and collection of traps on
- Each trap will be inspected by department entomologists and any psyllids collected will be tested for
- Testing of more than 7000 psyllids is required to determine a high level of confidence about the presence or absence of CLso in
- More than 1900 psyllids have been tested to
- While the department is targeting known populations of TPP, commercial growers in any area of WA may request surveillance and testing of TPP to inform their on- farm management and business
- Other states are required to develop surveillance plans for the pest in accordance with national and international
- Detection of a suspect or confirmed case of CLso will be reported to the Australian Chief Plant Protection Officer and CCEPP.
- The department will undertake chemical (pesticide) trials at its laboratory facilities to establish a list of effective chemicals for use in tomato, potato and capsicum crops.
- Results of the chemical trials will be submitted to the Australian Pesticides and Veterinary Medicines Authority (APVMA) for
- The department will also carry out chemical effectiveness trials to assist post- harvest disinfestation of capsicum, chilli and
- Department researchers will undertake collaborative trial work with biological control providers to evaluate potential biological control agents (i.e. predator insect species).
- This research will feed into the future national TPP research and development agenda.
- The department’s TPP market access working group continues to work with the state and territory jurisdictions to re-establish markets suspended following the detection of TPP in WA. The department is achieving this through the development of workable and cost-effective
- Future interstate trade for host material will be influenced by CLso surveillance outcomes. No detection of CLso under the agreed surveillance program will provide a high level of confidence of WA’s freedom from
- WA will be able to use this improved level of confidence in market access negotiations with other state and territory
Enterprise and national management plans
- The department will work with TPP-affected industries in WA to develop enterprise management plans to help minimise the spread and impact of the pest.
- Industry will be encouraged to take a leadership role in their development and implementation of enterprise management plans which are critical to the effective control of
- Completed enterprise management plans will include:
- pest and pathogen biology and their identification
- identification of risk pathways
- control and management options
- on-farm biosecurity awareness and implementation, including signage and
- post farm-gate
- A National Management Plan will be developed to give the community and trading partners confidence TPP is being actively managed in Australian production
Quarantine Area Notice
A Quarantine Area Notice remains in place to help minimise the spread of TPP until a cost benefit analysis is completed by the department.
Detailed information in relation to movement and treatment requirements for specified zones under the Quarantine Area Notice is available from www.agric.wa.gov.au/tpp
Check and report
Commercial growers are encouraged to check for, and report sightings of unusual insects or damage to their plants through the MyPestGuide reporter app or by contacting the department on 1800 084 881.
Good farm biosecurity procedures should be in place to prevent the entry, establishment and spread of pests and diseases. More information on biosecurity is available at the Farm Biosecurity website www.farmbiosecurity.com.au
