Report Number
Pest Id
Potato spindle tuber viroid - (PSTVD0)
Report Status
Currently, PSTVd is known to occur in the hosts listed below. Greenhouse tomatoes (Lycopersicon esculentum) (single property, South Australia) and field tomatoes (Queensland) Ornamental/white potato vine (Solanum laxum Spreng, synonym S. jasminoides) (Queensland) Annual Saltbush (Western Australia)  Atriplex semilunaris (Western Australia) Thorny saltbush (Rhagodia eremaea) (Western Australia) Streptoglossa sp. (Western Australia) Flaxleaf fleabane (Conyza bonariensis) (Western Australia) Blackberry nightshade (Solanum nigrum) (Western Australia) Thornapple (Datrua stramonium) (Western Australia) Apple-of-Peru (Nicandra physalodes) (Western Australia) Malvaceae (Western Australia)
Pest Status (old values from ISPM 8 -1998 )
  • Present: only in some areas
  • Transient: actionable, under eradication

  • Present: not widely distributed and under official control
  • Present: transient
Geographical Distribution
Western Australia (Carnarvon), Queensland, South Australia (one property)

PSTVd has been identified in a range of hosts in Australia and its distribution has been verified through a national survey. In pest free areas, when found in commercial production systems, PSTVd is eradicated through crop destruction. PSTVd was detected in ornamental potato vine and non-commercial tomatoes in Queensland and in wild plants in Western Australia, indicating that it is potentially established in these regions. The symptoms of PSTVd vary and are dependent on the strain of the viroid in conjunction with the host species and stage of development. Some hosts detected with PSTVd have been reported to be asymptomatic. PSTVd can cause economic losses in a range of Solanaceae crops. Most areas of Australia are free from PSTVd. PSTVd remains a regulated pest and phytosanitary measures will be maintained. The pest status in Australian States and Territories is as follows: Present: in some areas of Australia (Western Australia at Carnarvon; Queensland) Transient: actionable, under eradication (South Australia) Absent: no pest records (Tasmania, Northern Territory) Absent: pest eradicated (New South Wales, Victoria)

PSTVd has been found in weeds and in tomato, capsicum and chilli crops and some ornamental plants. In pest free areas, PSTVd is eradicated upon detection in commercial production systems (Commercial production systems means commercial crops, nurseries and glasshouses). PSTVd is established in Western Australia at Carnarvon and in Queensland.
