Choueiri E., Abou Ghanem-Sabanadzovic N., EI Zammar S., Jreijiri F.

The overall average virus incidence was ca. 30 percent, ranging from 24 percent in peach to 36 percent in cherry. The most common viruses were Prunus necrotic ringspot virus (PNRSV), Prune dwarf virus (PDV) and Apple chlorotic leaf spot (ACLSV). Virus distribution differed greatly according to the location of orchards. PNRSV was dominant in peach (61percent) but it was also relevant in cherry (42 percent). The presence of PDV was consistently high (42 percent) in cherry and less (22 percent) in peach. ACLSV was 38 percent in cherry and 27percent in peach. Apple mosaic virus (ApMV), only in peach, was the least represented virus (2 percent). In two species, infections by two or more viruses (13 percent in peach and 19 percent in cherry) were also found. Plum pox virus (PPV) and three nepoviruses tested for (Tomato ringspot virus, ToRSV; Strawberry latent ringspot virus, SLRV; and Cherry leaf roll virus, CLRV) were not encountered.
