Abstract

Etiology, ecology, epidemiology and control of groundnut rosette disease in Africa.

Abstract

Groundnut rosette disease appears to be restricted to Africa and is transmitted persistently by Aphis craccivora. The virus causes up to 100% yield loss during years of severe epidemic. Infected plants contain two viruses, groundnut rosette virus (GRV) and groundnut rosette assistor virus (GRAV) and a viral satellite RNA. This paper reviews the aetiology, ecology and vector of the virus including their epidemiology and control strategies. Future research needs are suggested.
