Pesticide residues on fruit. V.—Harvest residues of codling moth insecticides on apples

Persistence and harvest residue studies on apples have been undertaken using the codling moth insecticides lead arsenate, DDT, 1‐naphthyl N‐methylcarbamate (arylam; Sevin) and the OO‐dimethyl and the OO‐diethyl S‐(3,4‐dihydro‐4‐oxobenz‐1,2,3‐triazin‐3‐ylmethyl) phosphorothiolothionates [azinphos‐methyl and ‐ethyl (Gusathion and Gusathion A), respectively]. After application of these insecticides at commercially used times and rates, harvest residues do not constitute a consumer hazard, except upon occasion with lead arsenate.
