Azinphos-methyl (Guthion) (also spelled azinophos-methyl) is a broad spectrum organophosphate insecticide manufactured by Bayer CropScience Gowan Co. and Makhteshim Agan. Like other pesticides in this class it owes its insecticidal properties (and human toxicity) to the fact that it is an acetylcholinesterase inhibitor.
