Abstract
The use of Co-Ral® (O-(3-chloro-4-methylumbelliferone) O,O-diethyl phosphorothioate) as a topical spray for the control of cattle grubs has created a demand for a method for determining residues of this pesticide in animal products. A colorimetric method has been developed, and clean-up procedures have been worked out for determining Co-Ral in fat and other tissues. The method has a sensitivity of 0.1 p.p.m. on a 50-gram sample or 0.2 p.p.m. on a 25-gram sample.Keywords
