Ronnel sprayed as a 0.5% emulsion on the ventral side of caged layers at a rate of 1 gal/l00 birds produced maximum residues of ronnel, 1.207 and 0.864 ppm, in skin and fat, respectively, at 1 day posttreatment. The maximum residue in eggs, 0.019 ppm, occurred 7 days posttreatment. No residues were detected in any tissues except skin at 21 and 28 days posttreatment. Residues in tissues of caged layers given a 2nd spraying 28 days after the 1st spraying were not greater than those produced after the 1st spraying. Also, with the 1st spraying, only skin had residues at 21 days posttreatment. However, at 28 days, there were residues in skin, and 2 samples of muscle contained residues of 0.008 and 0.003 ppm. No oxygen analogue of ronnel (dimethyl 2,4,5-trichlorophenyl phosphate) was detected in any tissue.
