Abstract
The appropriate action threshold for application of insecticidal sprays to control green peach aphid, Myzus persicae (Sulzer), on potatoes, Solanum tuberosum (L.), appeared to be ca. 30 apterae/105 leaves. For seed production, assuming a soil systemic was used at planting, an action threshold of ca. 10 apterae/105 leaves was indicated. Spraying on a schedule, even with effective aphicides, can result in late-season green peach aphid control problems more severe than occur on untreated potatoes. Serious outbreaks resulted when an insecticide to which the aphid is resistant was applied on a schedule. During this study, 2 insecticides, pirimicarb and fenvalerate, lost much of their original effectiveness against green peach aphid.
