Risultato della ricerca: Other

Abstract

After a recent detection of Citrus tristeza virus (CTV) in Calabria (Southern Italy), aninvestigation was initiated in the spring 2006 to survey for the virus in this Region. The survey showed thatCTV was not present in the nurseries which indicated that citrus mother plants and citrus plantlets ready formarketing have fulfilled completely the phytosanitary requirements. CTV was not detected in citrus-growingareas of Catanzaro, Cosenza and Crotone Provinces, but was found, at different levels in infected plants, in someorchards located in the Reggio Calabria and Vibo Valentia Provinces. Since the virus was detected not only inmaterial illegally imported from abroad but also in local varieties, aphid transmission of the virus to localcultivars is suspected. Molecular characterization of some of the detected CTV isolates showed that at leastthree different CTV accessions have been introduced in this Region.
