Many new hosts for sugarcane mosaic (SCMV) and maize dwarf mosaic viruses (MDMV) are reported. A set of grasses is suggested as a means of identifying and separating these viruses, especially where all these viruses have been known to occur in the same locality. We have resolved some of the differences of opinion reported in the literature by testing all the SCMV and MDMV strains under identical conditions on the hosts in question.
