The Problem

Increased sweetpotato production in sub-Saharan Africa is hampered by high incidence of virus diseases. Sweet potato virus disease (SPVD), caused by synergistic interaction between Sweet potato feathery mottle virus (SPFMV) and Sweet potato chlorotic stunt virus (SPCSV), can cause up to 98% yield losses. The crop is vegetatively propagated, and so viruses accumulate with each generation and are difficult to control.
