Incursion of tobacco ringspot virus in Italy
Tobacco ringspot virus (Nepovirus nicotianae, TRSV, EPPO A2 List) was detected in a Malus domestica plant conserved in the nuclear stock of mother plants at the Laimburg Research Centre (Alto Adige) in May 2023 during a routine phytosanitary inspection for the presence of quarantine viruses. The scion had been imported from North America in 2021, grafted on a Malus domestica rootstock and kept into post-entry quarantine facility until May 2023. It remained asymptomatic during this period.
