Plantain orchards in the major plantain production area in southern Nigeria were surveyed in 1995 for the occurrence of banana streak virus (BSV) disease. Plantain plants showing BSV-like symptoms were found in 37 of 71 villages visited and in 49 of 147 orchards. BSV was positively identified by ISEM and/or ELISA in 30 orchards in 27 villages. The incidence of symptomatic plants in an orchard ranged from 1 to 17% (mean 4.2%). Of 58 leaf samples taken from plants with symptoms and indexed for both BSV and cucumber mosaic virus (CMV), 36 (62%) tested positive for BSV and none tested positive for CMV. The survey results show that BSV is common and widespread in the plantain-growing area of southern Nigeria.
