Almond Prunus dulcis is a well known fruit grown for its unripe fruits and delicious seeds in Turkey. Agro ecological conditions in Trakya are suitable for almond production and promise great potential for establishment of commercial almond orchards. Some prevailing virus infections on almond trees however have reduced yield and quality in the region. In order to describe diseases and identify viruses 158 flower and 260 leaf samples were collected from symptomatic trees in 10 districts of region in 2010. By employing enzyme linked immunosorbent assay (DAS–ELISA), TAS-ELISA) and reverse transcriptase polymerase chain reaction (RT–PCR), Prunus necrotic ring spot virus (PNRSV), Prune dwarf virus (PDV) and Plum pox virus (PPV) viruses were identified. As a result of detection studies 31.15 % samples was found infected with PNRSV, 4.23 % of them had PDV, 1.92 % of them were infected with PPV individually and 1.54 % of them however infected with the mixture of PNRSV+PDV and PNRSV+PPV. So 38.85% of almond leaf samples were found infected with viruses in Trakya region of Turkey
