Grapevine leafroll is a complex disease that can be caused by any one of the nine serologically distinct closteroviruses, referred to as Grapevine leafroll-associated viruses 1 to 9 (GLRaV-1 to GLRaV-9). So far, it has been known the occurrence of GLRaV-1, GLRaV-2, GLRaV-3 and GLRaV-6 in Brazil. This work reports the identification of GLRaV-5 in leafroll-infected grape material from the State of São Paulo, by Biotine-ELISA. The virus was detected with low incidence in tested grape cultivars, except in 'Cardinal', which showed 100% infected. This is the first report of GLRaV-5 in Brazil.
