Virus infection, by a number of different types of viruses, is one of the most important constraints to sweetpotato production globally, especially in Sub-Saharan Africa (SSA). Sweet potato chlorotic stunt virus (SPCSV) and Sweet potato feathery mottle virus (SPFMV) are considered to be the most widespread and are particularly devastating when occurring in combination to cause the sweetpotato virus disease (SPVD). Beyond East Africa, there is no clear information about the prevalence and distribution of different viruses and virus strains infecting sweetpotato. This information is essential to enable control of the viruses. Diagnostic tests are not available for all viruses hence improved and cheaper diagnostic methods are required. In this poster, progress on improving sweetpotato virus diagnostics is reported.
