A survey was carried out in Apulian peach orchards to assess the presence and distribution of viruses and viroids. About 2,500 trees in 6-4 commercial plantings were individually sampled and checked by ELISA for Prunus necrotic ringspot (PNRSV), prune dwarf (PDV) and apple mosaic (ApMV) ilarviruses, apple chlorotic leaf spot closterovirus (ACLSV) and plum pox potyvirus (PPV). Search for peach latent mosaic viroid (PLMVd) was limited to 113 plants. Slightly more than one third (35,3 per cent) of the samples was infected by one or more viruses. The prevailing virus was PNRSV (52 per cent), followed by ACLSV (26 per cent). PDV (7,7 per cent) and ApMV (4,5 per cent). Mixed infections were about 10 per cent. PPV was not detected in any of the samples. PLMVd was identified in 27,4 per cent of the samples examined, most of American origin.
