Two viruses used in this study, Onion yellow dwarf virus (OYDV) and Tobacco rattle virus (TRV), were isolated from naturally infected onion (Allium cepa L.) plant growing in the field of onion plants during the survey carried out in 2007-2008 and 2008-2009 in seven Egyptian Governorates. The results indicated that the mean percentages of OYDV-infection were 24.48 and 19.98% and TRV-infection were 1.04 and 0.42% respectively in first and second seasons all over the seven governorates
