Abstract:Ronnel (O,O-dimethyl O-(2,4,5-trichlorophenyl) phosphorothioate; formerly designated Dow ET-57 and manufactured under the trade name Trolene) was administered orally to steers and heifers in a commercial feed lot in the Imperial Valley, California for control of Hypoderma lineatum (De Vill.) and H. bovis(L.). It was given in a bolus at the rate of 100 mg./kg. of body weight. Effective control of cattle grubs was obtained even in animals treated late following infestation. Best results were obtained when treatment was made before the grubs reached the animal's hack Hide damage and carcass trim were greatly reduced on the treated animals as compared with the controls. No significant weight gain of the treated animals over the controls was noted.
