By March 24, 2017 No Comments

Quarantine Area Notice update

Major changes to the Quarantine Area Notice (QAN) come into effect Monday 27 March 2017. The link to the notice is available here.

Three zones have been established to direct the movement and treatment of Solanaceous and Convolvulaceae plants and produce (i.e. tomato, potato, chilli, capsicum, eggplant, tamarillo, sweet potato) to contain and control the pest.

The Control (red) Zone applies to the Perth metropolitan area and the City of Mandurah, and the shires of Gingin, Murray and Chittering.

The Suppression (orange) Zone includes the shires of August-Margaret River, Beverley, Boddington, Boyup Brook, Bridgetown-Greenbushes, Brookton, Capel, Collie, Dandaragan, Dardanup, Donnybrook-Balingup, Harvey, Manjimup, Moora, Nannup, Northam, Toodyay, Victoria Plains, Wandering, Waroona, West Arthur, Williams and York and the cities of Bunbury and Busselton.

The blue ‘watch’ zone for the remainder of the State involves ongoing surveillance and reporting where the pest is suspected.

A map of the Quarantine Area zones is available online.

The revised measures aim to provide a more consistent approach for all producers in the metropolitan area and surrounds, where the psyllid is present, and strengthen efforts to limit its spread into regional areas.

These changes are in line with a national response plan which includes containment measures for tomato potato psyllid and increased testing and monitoring for the bacterium Candidatus liberibacter solanacearum (CLso).

The department acknowledges the efforts of many growers, and businesses, who have already been complying with measures and assisting surveillance activities to help limit the spread this pest.

Key changes

Individual Pest Control Notices still apply if the psyllid is detected on a property. These Notices are likely to include movement control and required treatments on affected crops.

More information on the QAN is available in the Frequently Asked Questions and zone movement flow charts for seedlings; fruit; ware potatoes; seed potatoes; machinery and equipment on the department website.

Host plants (seedling) movement – Movement of seedlings outside the Quarantine Area to other parts of the State require a three-step chemical treatment for host plants, as outlined in the QAN and must be found free of CLso under an approved testing program conducted by the department. To arrange testing contact TPP.BiosecurityOfficer@agric.wa.gov.au

Consigners of host plants to a destination outside the Quarantine Area must provide the department with advice of consignments to be moved. This advice must be provided to TPP-OperationsOfficer@agric.wa.gov.au a week prior to movement.

Movement of seedlings within the control zone require three-step treatment as outlined in the QAN.

Host fruit (eg capsicum, chilli, eggplant, tamarillo, tomato) – Host fruit produced within the control zone must receive approved post-harvest treatment to move outside of this area. Approved treatments are available on the department website.

An alternative post-harvest protocol for Solanaceous fruit involving a range of washing, flood spraying, brushing and drying methods is now available under a certification assurance arrangement.

Ware and processing potatoes Ware and processing potatoes produced within the Quarantine Area must be free of all above ground plant material and washed or brushed before movement.

Seed potatoes – Seed potatoes produced within the Quarantine Area must be found free of CLso under an approved testing program conducted by the department, prior to movement outside of this area to other parts of the State. To arrange testing contact TPP.BiosecurityOfficer@agric.wa.gov.au. They must also be free of all above ground plant material and washed or brushed before movement.

Machinery and equipment – Movement of machinery and equipment used in association with host plants on a property which is within the quarantine area and destined for a place outside the quarantine area, must be washed free of plant material and soil with high pressure hot water or treated with an insecticide.

Records of treatment must be kept.

National response update

The National Management Group – comprising all Australian governments, affected industries and Plant Health Australia – met on 22 March 2017 and agreed to a national response plan for the incursion of TPP.

The psyllid poses a significant threat to important horticultural crops and has the potential to transmit CLso.

The response plan includes control and suppression of tomato potato psyllid and increased surveillance to determine the existence of the ‘complex’ – where the psyllid and CLso exist together – and eradication where this ‘complex’ is found. To date, there has been no confirmed detection of CLso.

Surveillance for tomato potato psyllid and CLso is priority. This response component is 30 days, which will allow for critical information on the nature and spread of the pest to be collected.

The communique is available at the Australian Department of Agriculture and Water Resources website.

Interstate trade

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.

Practice sound farm biosecurity procedures 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
