APPLICATIONS
Biochemistry Cholinesterase inhibitor. The
separate optical isomers, due to the chiral phosphorus atom, show different
types of insecticidal activity and ability to inhibit acetylcholinesterase (H.
Leader & J. E. Casida, J. Agric. Food Chem., 1982, 30, 546). Mode of action
Non-systemic insecticide and acaricide with contact and stomach action.
