General description

Parathion-methyl is an organophosphate insecticide, which is extensively used for agricultural purposes. Its mode of action involves the inactivation of the enzyme acetylcholinesterase (AChE) in insects and also mammals. It undergoes degradation by soil microorganisms to yield p-nitrophenol as the product.
