Abstract:

In a series of 6 experiments conducted in southern California during the late falls and winters of 1961, 1962, and 1963 on control of the cabbage aphid, Brevicoryne brassicae (L.); and the green peach aphid, Myzus persicae (Sulzer), results generally showed that when maximum temperatures were below 70, parathion, endosulfan, naled, and azinphosmethyl did not provide effective control. Data indicated that insecticide residues of parathion, endosulfan, demeton and dimethoate on the crops sampled volatilize and are taken up more slowly and persist longer on leafy vegetables and on greens than on cabbage. This finding emphasized the need for a more thorough study of insecticides and their residues on different kinds or varieties of crops as well as of the various factors including weather conditions and insecticide formulation that might influence persistence of residues.
