Industry Update 14 - Tomato potato psyllid (TTP) complex

The Department of Agriculture and Food has confirmed one new detection of tomato potato psyllid (TTP) since the last update on 26 April 2017.

TTP has been confirmed on a total of 74 properties/locations, of which 42 are commercial horticulture properties, mostly in the metropolitan Control Zone.

There has been no detection of the associated bacteria Candidatus Liberibacter solanacearum (CLso) to date.

Response Update

As previously advised, the National Management Group* has agreed it is not technically feasible to eradicate TPP in Western Australia, and supports transitioning to a management program for 12 months, to May 2018.

*The National Management Group (NMG) is the decision making body for national exotic plant pest eradication programs under the Emergency Plant Pest Response Deed (EPPRD).

Transition to Management

The department is working with WA’s horticulture industry and national partners on a Transition to Management (TTM) plan to prepare industry to manage the pest.

The 12-month 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 the plan is developed.

TPP surveillance activities

During the next four weeks, department surveillance and diagnostic resources will be focussed in the metropolitan Control Zone to further determine the presence/absence of CLso in TPP in Western Australia.

Sticky traps will be installed on commercial and residential properties.  TPP samples will be tested for CLso.

Departmental surveillance activities will be scaled back during the cooler months when the psyllid is less active and recommence when weather conditions warm up in the spring, and there is increased TPP activity.

Growers can still send suspect TPP samples to the department for laboratory testing.

Quarantine Area Notice

A Quarantine Area Notice 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

Interstate trade

Update on market access

New South Wales, South Australia, Victoria, Queensland and the Northern Territory have introduced varying emergency interstate movement controls for tomato potato psyllid and CLso host plants, a range of non-host material and used machinery and equipment from WA.

Import restrictions are made by the receiving state or territory.

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: qa@agric.wa.gov.au.

The department’s market access team is developing proposed protocols and is in dialogue with other states to facilitate interstate trade for Western Australian host and non-host produce as quickly as possible.

Pathway Prioritisation Risk Assessment workshop

DAFWA is hosting a workshop in Adelaide next week (8 & 9 May) to discuss protocols to facilitate interstate trade and market access.

Representatives from each State government, Plant Health Australia, industry body AUSVEG, Nursery & Garden Industry Australia and selected industries impacted by TPP movement restrictions, have been invited.

The purpose of this workshop is to seek harmonisation and domestic and international equivalence across jurisdictions on the categorisation, treatment protocols and entry conditions for plants and plant products that are exported from WA.

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 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
