To which plants should we focus our attention?

Hidden infectin is determined for ornamental pot plants of the family Solanaceae, which includes also potato, tomato and other vegetables. Flowers of ornamental species are in the form of big horns, for example Datura Brugmansia (Datura) suavolens and B. cordata (since containing alkaloids, they are also called angel horns), or in forms similar to potato flowers, for example Solanum jasminoides.

In the event of spread of PSTVd, the most endangered would be potato and tomato. Since no treatment exists after infection, preventive is the most effective protection agains the infection - prevention of introduction and spread. 

Inclusion of PSTVd on List I.A.I provides also for its compulsory suppression with the aim of eradication.
