Abstract: The disease caused by the virus complex of tomato yellow leaf curl (TYLC) is extremely severe in tomato plants, notably in Central America and Europe, and is caused by a complex of begomovirus species. The disease becomes predominant even in areas with the presence of other begomoviruses. In Brazil, the problems arisen from begomovirus infection are one of the major factors for damages and increasing the costs. The introduction of the TYLC complex implies in a great threat for growers. This study aimed to carry out detection tests based on PCR (polymerase chain reaction) and specific hybridization on suspected samples collected in the São Paulo State, Brazil. A total of 46 samples with symptoms resembling those caused by the TYLC complex were collected in Campinas county. All samples were negative for the detection of Tomato yellow leaf curl virus and Tomato yellow leaf curl Sardinia virus, the two most important virus from the TYLC complex. This result suggested that the two species have not yet been introduced in Brazil or that they are not widespread.
