The tomato rugose virus (ToBRFV), which is a major threat to tomato crops, has been detected in Argentina, putting Brazil on alert to protect its own tomato crop. The virus has spread to several continents since it was first described in Israel in 2014. Researchers in Brazil are calling for mobilization and discussion to inform producers, technicians, and authorities about the risks and to establish partnerships to protect against the entry of the virus into the country.
