Sweetpotato, (Ipomoea batatas L.), is vegetatively propagated crop. Due to the following cycles of propagation, viruses are accumulated, which contributes to the decline of sweetpotato yield and quality. Stem cuttings of Abees cultivar were collected from several locations in Egypt and kept under controlled greenhouse conditions. Samples were tested for …

Both components of the virus complex that cause the sweetpotato virus disease (SPVD) in Nigeria can individually be transmitted by their respective vectors from diseased sweetpotato to healthy sweetpotato and to test plant, Ipomoea setosa. But in Isolation, neither the aphid nor the whitefly-transmitted component, both latent in sweetpotato, can …

Sensitive analytic techniques including double antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA), direct ELISA, dot-ELISA and reverse transcription polymerase chain reaction (RT-PCR) are compared and evaluated for their capability to reliably distinguish between healthy and sweet potato feathery mottle virus (SPFMV) infected sweet potato plants. The DAS-ELISA is not adequate …

The study aimed to assess the recent magnitude of virus diseases attacking sweet potato in the main production areas of the country. Ninety seven sweet potato fields were visited in eastern and southern Ethiopia in 2009 and a total of 235 symptomatic and 735 asymptomatic vine cuttings were collected. The …

Co-infection of Sweet potato chlorotic stunt virus (SPCSV, genus Crinivirus) with Sweet potato feathery mottle virus (SPFMV, genus Potyvirus) results in sweet potato virus disease (SPVD), a synergistic disease that is widely distributed in the sweet potato (Ipomoea batatas) growing regions of the world. Since both SPCSV and SPFMV are …

Sweetpotato (Ipomoea batatas L.) has a diverse range of positive characteristics including high yield per unit area, nutritional value, and resistance to several production stresses. However, diagnostics aspects for detection of sweetpotato feathery mottle virus (SPFMV) are not well understood. This paper documents such aspect via expression of SPFMV coat …
