Abstract:

Systemic insecticides were applied to the soil on each side of potato seed pieces at planting time and/or were side dressed into the soil when 75% of the plants emerged, and multiple foliar sprays were applied to obtain seasonal control of Myzus persicae (Sulzer) and the suppression of potato leaf roll virus on 'Russet Burbank' potatoes in eastern castern Washington. Aldicarb gave superior control of aphids and suppressed spread of the virus; disulfoton gave fair control of aphids, but not much suppression of potato leaf roll virus; and phorate did not give sufficient control of aphids or the disease. The 2 applications of the systemic insecticides were more effective than either single application. Endosulfan and oxydemetonmethyl as foliar sprays (2-5 applications) gave better control of aphids than demeton and disulfoton but none significantly suppressed spread of the virus. All applications of systemic insecticides in combination with multiple applications of foliar spray gave significant control of aphids, and most treatments significantly suppressed the spread of disease,
