TPP surveillance activities
During the next four weeks, department surveillance and diagnostic resources will be focused in the metropolitan Control Zone to further increase confidence levels that Candidatus Liberibacter solanacearum (CLso) in TPP is not present in Western Australia.
Sticky traps are currently being installed on commercial and residential properties, with all TPP samples being tested for CLso. To date there has been no detection of CLso in TPP or in host plants within Western Australia.
Moving forward, departmental surveillance activities will be scaled back during the cooler months when the psyllid is less active.
Transition to Management
As previously advised, the determination that TPP is not technically feasible to eradicate was endorsed at a National Management Group (NMG) meeting held in April. As a result, the department has moved its focus to increasing confidence levels that CLso in TPP is not present in Western Australia.
With support of NMG, the department is working with WA’s horticulture industry and national partners on a plan to prepare industry on how to manage the pest.
This plan will include targeted surveillance, control options on-farm, supply chain management, and restoring access to interstate markets for affected produce.
The national Consultative Committee on Emergency Plant Pests will continue to meet while this plan is being developed.
Quarantine Area Notice
A Quarantine Area Notice currently remains in place to help minimise the spread of TPP. The department is undertaking a cost-benefit analysis of maintaining the Quarantine Area Notice in consultation with industry.
The Quarantine Area Notice divides Western Australia into three quarantine zones – a Control Zone, Suppression Zone and Watch Zone, to direct the movement and treatment of commercially-produced vegetables and seedlings. 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
Update on market access
DAFWA hosted a two-day workshop in Adelaide (8 and 9 May) to discuss protocols to facilitate interstate trade and market access around tomato potato psyllid movement restrictions.
The workshop was positive and valuable with the other States agreeing in principal to support risk mitigation and treatment measures put forward by DAFWA for a range of non-host material (i.e. fruit, leafy vegetables, grains, nursery stock). These are workable for many WA growers and offer the appropriate level of protection for the other states.
Representatives from the Commonwealth and jurisdictions, Plant Health Australia, industry body Ausveg and some local WA representatives from industry, including vegetablesWA, were involved in the discussions.
Industry will be notified as these agreements are finalised and implemented.
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.
Exporters should contact the Quarantine WA Exports Officer to verify export requirements: Phone: 9334 1800, Fax: 9334 1880, Email: email@example.com.
Visit the department’s market access webpage for the latest information on interstate trade.
Check and report
Commercial growers are encouraged to continue 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
