First report of tomato chlorosis virus in Egypt
In autumn 2013, tomato plants (Solanum lycopersicum) presenting symptoms of leaf yellowing were observed both in the greenhouses and fields of the experimental station of the Faculty of Agriculture at Giza governorate. The presence of Tomato chlorosis virus (Crinivirus, ToCV - EPPO A2 List) in tomato plants was confirmed by RT-PCR. Plants in the vicinity of the infected sites were tested for the presence of ToCV. Out of 52 different plant species tested within 22 families, 44 tested postive for ToCV. Thirty seven out of these 44 plant species were considered as new hosts for ToCV. In another survey in 2017-2018, symptomatic and asymptomatic tomato samples were collected from open fields from Fayoum, Giza and Nobaria regions in Egypt (north of the country) and tested for a number of viruses. ToCV was detected in 5 out of 36 samples.
The situation of Tomato chlorosis virus in Egypt can be described as: Present.
