| Abstract: | Investigations were carried out in the main stone-fruit growing areas of Lebanon to assess the phytosanitary condition of commercial orchards. The presence of virus and virus-like diseases and their identification was ascertained through: (i) field surveys, (ii) sap transmission to herbaceous hosts, (iii) graft transmission to woody indicators; and (iv) ELISA and IEM tests. The mean infection level was 25%. ranging from 5% in apricot to 45% in cherry. The following viruses were identified: apple chlorotic leaf spot trichovirus (ACLSV), prunus necrotic ringspot (PNRSV) and prune dwarf (PDV) ilarviruses. Plum pox potyvirus (PPV), apple mosaic ilarvirus (ApMV), and six nepoviruses tested for (SLRV, TBRV, RRV, CLRV, ArMV and ToRSV) were not encountered. |
