Potato spindle tuber viroid detected on ornamental Solanaceae in the Czech Republic

In 2007, an extensive survey on Potato spindle tuber viroid (Pospiviroid, PSTVd – EPPO A2 List) was carried out on ornamental Solanaceae by the Czech NPPO. The survey was mainly targeted at Solanum jasminoides and Brugmansia species. A total of 91 samples from 35 locations were tested, including 50 samples of S. jasminoides and 41 samples of other species (Brugmansia sp., Solanum rantonnetii, Petunia sp., Lycopersicon esculentum, S. muricatum, Capsicum sp.). The presence of PSTVd was confirmed at 25 locations, mainly on S. jasminoides. PSTVd was also detected in Petunia x hybrida ‘Surfinia’ samples from 2 growers, in 1 sample of Brugmansia and 1 sample of S. muricatum. In addition, during this survey the presence of Tomato chlorotic dwarf viroid (Pospiviroid) was detected in Petunia x hybrida ‘Surfinia’ (see EPPO RS 2008/026).
The situation of Potato spindle tuber viroid in the Czech Republic can be described as follows: Present, first detected in 2007 in symptomless ornamentals (Solanum jasminoides, Brugmansia, Petunia), under eradication
