Permethrin, methomyl, and EPN-methyl parathion were combined with Elcar® (Baculovirus heliothis) in laboratory and field studies. No significant differences were detected between observed and expected mortality of Heliothis zea (Boddie) larvae in the laboratory, although slight increases in mortality were observed in some tests. In a small plot test on cotton, reduced rates (0.125, 0.25, and 0.5X the recommended rate) of permethrin, methomyl, and EPN-methyl parathion were combined with a recommended rate of Elcar. Permethrin-Elcar and methomyl-Elcar plots produced yields equal to those treated with Elcar alone, while EPN-methyl parathion plots had reduced yields.
