TPP/CLso spring surveillance complete

The Western Australian Department of Primary Industries and Regional Development has recently completed the spring round of surveillance for Tomato potato psyllid (TPP), which included testing TPP for Candidatus Liberibacter solanacearum (CLso). TPP can carry the bacterium CLso which is associated with Zebra Chip disease in potato.

The significant surveillance campaign targeting known populations of TPP across the Perth metropolitan area and surrounds was undertaken as part of the nationally-agreed Transition to management plan. The WA community has shown great support for our horticultural industries by offering to host a sticky trap at more than 1000 sites.

Over 4000 TPP were tested for CLso with no positive detections of the bacteria to date.

Some interstate markets require proof of area freedom from CLso – no positive detection of CLso under the agreed surveillance program will provide a high level of confidence of WA’s area freedom.

A further round of surveillance is anticipated to commence in early 2018. WA’s CLso status will be assessed following the completion of surveillance next year.

The department, in collaboration with industry, continues to progress other work under the Transition to management plan including the development of enterprise management plans for affected industries and trials of control options for TPP.

The department has recently updated the commercial grower Frequently Asked Questions on the TPP industry webpage – www.agric.wa.gov.au/tpp/industry-information.
