Update of the situation of Tomato brown rugose fruit virus in Mexico
In Mexico, Tomato brown rugose fruit virus (Tobamovirus,ToBRFV- EPPO Alert List) was first observed in 2018 in Michoacán (EPPO RS 2019/014). Further surveys were carried out to assess the presence of the virus in Mexico. As of February 2019, 117 outbreaks were found in 20 States (Aguascalientes, Baja California, Baja California Sur, Chiapas, Chihuahua, Coahuila, Colima, Durango, Guanajuato, Hidalgo, Jalisco, Michoacán, Morelos, Puebla, San Luis Potosi, Sinaloa, Sonora, Tamaulipas, Yucatán, Zacatecas). ToBRFV is causing damage on tomato (Solanum lycopersicum) and Capsicum sp. crops.
A positive sample for ToBRFV was also detected in aubergine (Solanum melongena) in the municipality of Elota (State of Sinaloa) in December 2018. This is the first reported case on S. melongena. It may be noted that in another study, inoculation trials did not result in virus transmission to S. melongena (cv. Classic, cv. 206 - Luria et al., 2017).
Phytosanitary measures are applied to mitigate the entry and spread of ToBRFVon the Mexican territory. They include phytosanitary requirements for the importation of seeds, seedlings, plants and cuttings of tomato, capsicum and aubergine as well as national regulation for the production of propagative material of tomato, capsicum and aubergine.
