A number of surveys were carried out in the main stone fruit growing areas of Malatya, Elazig, Igdir, Erzincan and Erzurum provinces of East Anatolia (Turkey) for the detection of Prunus necrotic ringspot (PNRSV) and Apple chlorotic leaf spot (ACLSV) viruses. A total number of 1451 samples were tested by ELISA (1319 apricot, 97 cherry, 17 peach, 9 plum and 9 sour cherry). The presence of PNRSV and ACLSV was proved by ELISA and mechanical inoculations. ACLSV was detected on apricot, sweet cherry and peach but not on plum and sour cherry. The incidence of ACLSV infection in all species was 0.34%. PNRSV was detected on sweet cherry and peach but not on apricot, plum and sour cherry. The infection level of PNRSV was 0.27% on the tested stone fruits. Total infection ration of East Anatolia was determined as 0.82% induced by ACLSV and PNRSV. The sanitary status of stone fruits was satisfactory. Considering the total infection level of stone fruits tested, the East Anatolia was determined as the cleanest apricot culture area of the world.
