Change in Victoria’s silverleaf whitefly (SLW) area freedom status
Silverleaf white fly (SLW) is a significant biosecurity threat to a range of plant industries.
Victoria previously maintained an area freedom program for the pest except for a 50km radius around the townships of Murchison, Shepparton and Gillieston.
Recent detections of SLW in East Gippsland indicate that the pest has now more broadly established across Victoria.
Due to the further spread of SLW across Victoria, the state’s area freedom status does not meet national biosecurity requirements. Effective 1 August 2021, SLW will be considered as an established pest in Victoria.
From this date, producers consigning SLW host or carrier material to a sensitive interstate market including Western Australia and Tasmania must ensure consignments are treated in accordance with movement conditions set by these markets.
Entry conditions by destination:
- WA and TAS – Entry conditions related to SLW apply.
- New South Wales, Queensland, South Australia and Northern Territory – no entry conditions related to SLW.
SLW Biotype B feeds on over 600 plant species including vegetable, field, ornamental and weed species including: cucurbits, tomatoes, eggplant, capsicum, potato, brassicas, legumes, lettuce, sweetpotato, and cotton.
