The Department of Agriculture and Food, Western Australia (DAFWA) is the lead agency in control and containment measures for tomato potato psyllid (TPP).
This update contains information specific to those industries affected by TPP and Candidatus Liberibacter solanacearum (CLso) interstate trade movement restrictions.

Protocols for TPP carrier produce
Following the workshop held in early May in Adelaide, work on developing protocols supporting the in-principle agreements made by the other jurisdictions has continued as a priority.
Protocols for inspection, washing and spray treatments have been developed and were sent to the other jurisdictions for approval on Monday 22 May, 2017.
These protocols will be reviewed and, if approved, each state will change their entry conditions. DAFWA will then work with growers to help them meet these protocols.
These protocols relate to the following categories; strawberries, pack house packed vegetables and non-host nursery stock.
If growers have crops that are ready for immediate export, they can apply for an import permit from the receiving state. These permit requests are to be sent to the DAFWA Market Access team: TPP-MarketAccess@agric.wa.gov.au.
Please check the latest interstate trade requirements in relation to plant material and produce. Full details of the entry conditions are updated on the NSW, Victorian and South Australian department websites.
CLso testing for potatoes
Protocols developed by DAFWA to enable interstate movement and trade of potatoes have not been accepted by NSW, SA and Victoria. Further work is required towards reaching national agreement on CLso testing methods.
Resources have been allocated for DAFWA to work with national sub-committees on plant health diagnostics and surveillance, to help enable an agreement on acceptable CLso testing methods.
New protocols for movement of potatoes from WA into other states will be developed once there is agreement on acceptable methods for CLso testing.
The movement of potatoes will depend on the acceptance of these protocols by the other jurisdictions. All of this work will take time.
DAFWA has conducted fryer testing; where potato samples are fried and inspected for signs of the bacteria, which presents as dark bands or stripes, as part of the national response.
Suspect samples are retested and if required, a polymerase chain reaction (PCR) test is conducted in the South Perth lab.
DAFWA has tested 6.6 tonnes of potatoes – over 32,000 tubers. There is no evidence of CLso at this time.
Update on TPP surveillance activities
TPP and CLso surveillance and control activities are continuing in the control area. Please refer to the latest Industry update for more information.
