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. Exhibits a translaminar effect. Has ovicidal properties. Uses Control of insects (particularly Lepidoptera) and mites on cotton, maize, sugar beet, soya beans, potatoes, vegetables, and other crops, at 250-1000 gha. Phytotoxicity Slight reddening of cotton may occur.
