First report of Tomato chlorosis virus in Brazil
During 2006 and 2007, surveys were carried out in the region of Sumaré in Brazil (São Paulo State) on virus diseases of tomato (Lycopersicon esculentum). Observations were made in 3 tomato fields and it was found that some plants showed symptoms of interveinal chlorosis and necrosis on the basal leaves. Symptoms were only observed at a low incidence on old and fruit-bearing plants, and affected plants were randomly distributed within the fields. Laboratory analysis (electron microscopy, RT-PCR, sequencing, whitefly transmission tests) confirmed the presence of Tomato chlorosis virus (Crinivirus, ToCV – EPPO A2 List) in diseased tomato plants. This is the first report of ToCV in Brazil.
The situation of Tomato chlorosis virus in Brazil can be described as follows: Present, first found in 2006 in field tomatoes near Sumaré, São Paulo State.
