The percentage of field grown sweet corn plants infected by maize dwarf mosaic virus (MDMV) was significantly less for plants receiving applications of mineral oil (mineral oil = 15.4% and mineral oil and aphicide = 16.7%) than plants untreated (23.2%) and plants having only an aphicide treatment (27.7%). The mineral oil had no adverse affect on aphid population growth. The mineral oil caused no phytoxicity. Alates of the following species of aphids, known to transmit MDMV, were trapped: corn leaf aphid, Rhopalosiphum maidis (Fitch); English grain aphid, Macrosiphum avenae (F.); green peach aphid Myzus persicae (Sulzer); and potato aphid, Macrosiphum euphorbiae (Thomas).
