Abstract

Cowpea mild mottle virus (angular mosaic of beans).

Abstract

Cowpea mild mottle virus (CPMMV) infects a wide range of cultivated legumes. It causes severe mosaic and/or necrosis on the leaves, stems and pods of beans (Phaselous), cowpea (Vigna) and soyabean (Glycine max). Yield losses of 64-80% have been recorded in groundnuts in Kenya (Bock et al., 1976, 1977) and 10-100% in soyabean in Brazil and Argentina (Brown and Rodrigues, 2017). The virus is transmitted in a non-persistent manner by the whitefly, Bemisia tabaci.
