Quarantine Area – approved treatments for movement of TPP host plants

A Quarantine Area Notice is in place to help minimise the spread of the Tomato potato psyllid (TPP) in Western Australia.

Commercial growers should be familiar with the Notice, including Clause 4, which sets out the spray regime required for movement of commercial host plants, such as seedlings or nursery stock, from the Quarantine Area to other areas in Western Australia.

 Alternative approved treatments

Clause 5 of the Quarantine Area Notice allows movement of host plants from the Quarantine Area if prepared in an approved manner.

The alternative approved manners of preparation for movement published on the department’s website, details the preparation required to allow commercial growers to move host plants by applying abamectin or bifenthrin or spirotetramat within 7 days prior to movement, in addition to spraying plants with methomyl no more than 36 hours prior to movement.

These treatment guidelines maintain a satisfactory level of effectiveness against TPP while improving the practicality of spray application and dispatch timing for the nursery and garden industry.

QAN treatment guidelines apply to the movement of host plants within Western Australia only. Records of treatment and the details of transporters and consignees must be kept.
