A detailed characterization of two South African isolates is given. One isolate is transmitted by Schizaphis graminum (Rondani) and is SGV-like. The other is transmitted by Rhopalosiphum padi (L.) and Diuraphis noxia (Mordvilko), and is related to PAV-like isolates. The latter has isometric particles 25 + 0.8 nm in diameter and apparent buoyant density of 1.435 g/cm3 in cesium chloride and a protein of Mr 24.5 kDa that degrades to 22.5 kDa on storage. It also contains ssRNA of Mr 1.8 MD and produces dsRNA of Mr 1.8 MD and produces dsRNA of Mr 3.4 MD in infected plants. Both isolates appear relatively vector nonspecific
