Rosette is the most destructive virus disease of groundnut in sub-Saharan Africa. It is caused by a complex of groundnut rosette assistor virus, groundnut rosette umbravirus and its satellite RNA. The disease appears to be indigenous to Africa. The disease is thought to have spread to the introduced groundnut from indigenous host plants. Unresolved issues of importance include the nature of the primary source(s) of inoculum, the means of survival of the disease and vector during unfavourable periods, and the distances over which the aphid vector can disperse and disseminate virus. It is suggested that the ecology and epidemiology of rosette disease need further investigation. It is also suggested that progress can be made by developing a co-ordinated multi-disciplinary research programme, and by making full use of the latest techniques. It is concluded that this information could prove useful for explaining the sporadic disease epidemics that cause serious crop losses and occasional total crop failure, and would facilitate the development
