Abstract

A spot test for detection of two carbamate pesticides namely thiophanate methyl and cartap is described. Thiophanate methyl and cartap produced crimson coloured spots when treated with copper hexacyanoferrate reagent on silica gel-G spot test plate. The sensitivity of this spot test for detection of thiophanate methyl and cartap was found to be 5μg. The reagent did not respond positively with other carbamates namely carbaryl, carbosulfan, methomyl and propoxur. The described method is simple, sensitive, quick, and reliable for detection of these carbamates in different matrices including biological samples.
