First report of tomato brown rugose fruit virus in Egypt
In June 2019 leaf samples from hybrid tomato (Solanum lycopersicum) were collected in 4 sites in Fayoum and Ismailia Governorates. Twenty samples were collected from plants with viral symptoms and 9 from asymptomatic plants. The diseased samples showed leaf mosaic, deformation and necrosis, as well as discoloration and deformations on fruits. Samples were tested by DAS-ELISA for the presence of viruses that induce similar symptoms on tomato plants. Out of the 20 diseased samples, 4 tested positive for Tomato spotted wilt virus (Orthotospovirus, TSWV – EPPO A2 List), 3 for Pepino mosaic virus* (Potexvirus, PepMV - EPPO A2 List), 3 for Tomato mosaic virus (Tobamovirus, ToMV), 2 for Tomato chlorosis virus* (Crinivirus, ToCV - EPPO A2 List), 6 for Tomato brown rugose fruit virus (Tobamovirus, ToBRFV – EPPO Alert List), and 3 samples had a mixed infection with TSWV and ToBRFV. The identity of ToBRFV was confirmed by RT-PCR. This is the first report of ToBRFV in Egypt.
The situation of Tomato brown rugose fruit virus in Egypt can be described as: Present.
* The EPPO Secretariat had no previous reports of the presence of PepMV and ToCV in Egypt.
