Abstract
Preplant application of carbofuran, weekly sprays of acephate, or Sunoco 6E oil emulsion failed to delay or reduce incidence of 3 non persistent aphid transmitted viruses of tobacco, potato virus Y (PVY), alfalfa mosaic virus, and tobacco vein mottling virus, in replicated field experiments. Correlation coefficients for PVY incidence and the number of alate aphids trapped 3 wk previously were 0.87 (P<0.01), 0.40, and 0.35 for Aphis spp., Myzus persicae (Sulzer) and Rhopalosiphum maidis (Fitch), respectively, suggesting Aphis spp. were the significant vectors.
