Tests for the control of the green peach aphid (Myzus persicae (Sulz.)) on late-crop plantings of potatoes were made at Prosser, Wash. Satisfactory control was either not obtained or, if so, only for 3 to 7 days following applications of several dosages of schradan, demeton, Thimet, Guthion, Am. Cyanamid 12008, Chlorthion, and parathion in 1955, and Diazinon, schradan, and combinations of schradan and Diazinon in 1956 during the period that the numbers of winged migrants present in the area steadily increased. After the peak of aphid migration had been passed and the numbers of winged aphids steadily diminished to the end of the season, many treatments that had previously been unsatisfactory gave good control for 13 to 17 days.
