Sweet potato feathery mottle virus (SPFMV)
The virus causes the sweet potato virus disease together with the Sweet potato chlorotic stunt virus (SPCSV). Infections by both viruses can cause serious yield losses. For example during a comparative trial in Uganda, yield losses by SPCSV were estimated at 14–52% and those by mixed infections of both viruses at 60–95% depending on the cultivar (Adikini et al., 2016). SPFMV is transmitted by aphids (e.g. Myzus persicae or Aphis gossypii) in a non-persistent manner, as well as by planting infected tubers. This disease can be managed through the use of resistant cultivars.
