The Department of Agriculture and Food has confirmed three new detections of tomato potato psyllid during the past week. The psyllid has now been confirmed on 67 properties, with the majority still in the metropolitan area.
There are 12 detections in regional areas outside the Quarantine Control Zone. You can view a map of the quarantine zones and more information about the these at www.agric.wa.gov.au/tpp.
New detections in regional areas include two commercial horticulture properties in the Busselton area and one commercial horticulture property in the Manjimup area.
Surveillance and testing
- Vital surveillance for the psyllid and the bacterium Candidatus liberibacter solanacearum (CLso) continues to be a focus.
- Department officers have inspected more than 780 commercial and non-commercial properties across the state.
- More than 4800 surveillance ‘sticky’ traps have been installed across regional and metropolitan areas since surveillance activities began. Traps are collected for analysis several days later.
- Every trap is visually inspected by department officers for the tomato potato psyllid.
- Large volumes of insect and plant material have been tested.
- Psyllids found on a trap undergo diagnostics to determine morphology, and are tested for the bacteria, with no detections of CLso to date.
- More than 2200 plant samples have been tested for CLso, with no detections.
- More than 1600 tuber samples have had the ‘zebra chip test’ for CLso with no positives.
Containment and suppression measures for the TPP complex continue as a priority under the national response agreement.
Major changes to the Quarantine Area Notice (QAN) are now in effect for commercial and non-commercial specified plants and produce.
Detailed information in relation to movement and treatment requirements for specified zones under the QAN was included in the previous Industry Update (10), issued 24 March 2017. The latest information is also available from www.agric.wa.gov.au/tpp
Individual Pest Control Notices may be applied where the psyllid is detected on a property.
New South Wales, South Australia, Victoria, Queensland, Tasmania and the Northern Territory have emergency interstate movement controls in place for tomato potato psyllid and Candidatus liberibacter solanacearum (CLso) host fruit, vegetables and plant material, and used machinery and equipment from WA.
Please check the latest interstate trade requirements in relation to plant material and produce.
Exporters should contact the Quarantine WA Exports Officer to verify export requirements:

The department and industry are urgently seeking clarity on these measures, and reiterated the need for them to be in line with international guidelines and scientific evidence.
The department has created a specific market access team and is negotiating proposed protocols for interstate trade of seed potatoes and nursery stock, and is reinforcing to national bodies the need for this process to be handled as a priority given the economic implications for WA producers.
Check and report
Commercial vegetable producers, particularly in regional areas, are urged to check for signs of the psyllid and report via MyPestGuide Reporter app, email or phone.
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 farmbiosecurity.com.au
