viroid
Brazil, China, Mexico, Thailand, The Republic of Korea
Mainly solanaceous crops, capsicum, and ornamentals
PSTVD0
Successful eradication of the viroid has been reported for the USA and Canada. PSTVd-7 data shows little evidence of asymptomatic plants and testing of asymptomatic plants did not increase detection of Potato spindle tuber viroid significantly, if at all. Concluded that inspection for Potato spindle tuber viroid symptoms was a "good aid" in determining if a tomato crop was infected with the viroid.
5 Known Hosts
Capsicum annuum
pepper
Yes
CABICPC, ISFRPLD
ISF RPLD concludes that seed as a pathway is uncertain, because seed transmission was shown in the laboratory. However, significant references exist indicating that under certain situations, Potato spindle tuber viroid may be seed transmitted.
Yes
RT-PCR
RT-PCR is the standard method of the NSHS.
PSTVd-10, PSTVd-8, PSTVd-9, NSHSUSDA, PSTVd-11
Biological, Cultural, Mechanical
References suggest using PSTVd certified free seed, field monitoring and infected plant removal, though field detection may be difficult. Seed treatments are ineffectual.

Petunia spp.
petunia
No
PSTVd-10
Seed transmission in artificially inoculated plants in the laboratory. Though seed may be implicated, no references found indicating that seed is a pathway in nature.

Solanum melongena
eggplant
Not a host
PSTVd-10, ISFRPLD, EPPO, PSTVD-17
Eggplant is not a known natural host of PTSVd. It has only been used as an experimental host in various studies. Seed transmission was not found, however it was present in the placenta and ovary wall but not the ovules.

Solanum tuberosum
potato
Yes
CABICPC, EPPO, PSTVd-15, PSTVd-12, PSTVd-13
Potato is considered the main host of PSTVd. It is reported to be transmitted via true potato seed (TPS) but is reported to primarily spread mechanically.
Yes
RT-PCR
CABICPC, EPPO, PSTVd-14
Mechanical,
Proper sanitation procedures are important to prevent mechanical transmission. Ensure use of healthy seeds.
