Identification of the East African strain of Sweet potato chlorotic stunt virus as a major component of sweet potato virus disease in southern Africa
Plant Disease 82 (9), 1063-1063
Abstract: During 1998, sweet potato, Ipomoea batatas, plants grown in Zambia were surveyed for virus diseases. Plants with symptoms of severe stunting, leaf distortion, chlorosis, mosaic, or vein clearing were examined. The presence of sweet potato feathery mottle potyvirus (SPFMV) as well as sweet potato chlorotic stunt crinivirus East African strain (SPCSV-EA) was demonstrated in 22 symptomatic plants using enzyme-linked immunosorbent assays. SPFMV and SPCSV-EA was also detected in 2 samples collected near Antsirable, Madagascar. The disease incidence in that region was generally <1% but occasionally reached >20%.
