Abstract

Virus infections of cowpea.  Vigna unguiculata. are common in South Africa. There are three types of symptom found in the field viz. a vivid yellow mosaic with dark green blisters; dark green veinbands with necrosis and severe malformation, and a mild veinbanding or mosaic. There is no evidence of seed transmission but Aphis species are efficient vectors.
