The pesticides were created for control of insect born deceases affecting man and in the protection of crops and live stock. Carbamate group of pesticides are also use for the same manner. Because of the ease of their availability and low cost the insecticides are often misused for homicidal and suicidal and sometime in accidental poisoning. Identification of those pesticides becomes essential to protect the ecology/mankind from the adverse effect of pesticide residues and forensic toxicology and criminology purposes. Thin layer chromatography and spot tests are found to the best choice for routine work in toxicology purposes for detection of carbamate pesticides. Thus several chromagenic reagents and solvent systems are studied which shows different colour spots after reaction with these insecticides and thus help in their identification. A review of the identification techniques of carbamate insecticides namely Carboryl, Carbofuran, Methomyl, Propoxur, Thiophanate methyl and Cartap by using thin layer chromatography technique and spot test are reported in this paper.
