Il viroide del tubero fusiforme della patata individuato in Cestrum nocturnum in Campania.

During the summer 2010, an asymptomatic plant of Cestrum nocturnum, grown in a nursery of Anacapri municipality (province of Naples, Campania region), was found infected by potato spindle tuber viroid (PSTVd). This further occurrence of PSTVd in Cestrum nocturnum confirms that the plants belonging to the Cestrum genus could represent a potential reservoir of PSTVd. Consequently, to contain the disease, the sanitary inspections must necessarily be extended to the species belonging to this genus. Some epidemiological aspects, as well as the main actions to be taken to prevent the spread of the disease caused by PSTVd, are also discussed. A brief reference of the current legislation in the European Community concerning the quarantine organisms concludes this note.
