Dimethoate is a widely used organophosphate insecticide used to kill insects on contact. It was patentedand introduced in the 1950s by American Cyanamid. Like other organophosphates, dimethoate is an anticholinesterase which disables cholinesterase, an enzyme essential for central nervous system function.
