A combination of thin-layer chromatography and infrared spectrophotometry technique was used for identification of trace amounts of some organophosphorus insecticides (dimethoate and a mixture of methylparathion-sumithion) extracted from plant materials. The advantages of this method are the relative simplicity, the rapidity, the reliability of identification in one or mixture of insecticides, and the possible application to another insecticides.
