2019 SASHA Brief 17. Are begomoviruses a threat to sweetpotato production in Sub-Saharan Africa?

Begomoviruses have progressively been reported to be infecting sweetpotatoes throughout the world. Despite showing few symptoms, limited studies have reported them to have a varying but significant impact on root quality and yield. A cultivar with moderate resistance to Sweet potato feathery mottle virus (SPFMV) and/or Sweet potato chlorotic stunt virus (SPCSV) had a yield reduction of 47% from of single infection of a begomovirus, in contrast to a SPVD susceptible cultivar, which was hardly affected by it.
