History Herbicide reported by H. Gysin (Chem. Ind. (London), 1962, p. 1393). Introduced by J. R. Geigy S.A. (now Syngenta AG). Patents CH 337019; GB 814948 Manufacturers Griffin; Makhteshim-Agan; Syngenta

Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Also inhibits oxidative phosphorylation. Mode of action Selective systemic herbicide, absorbed by the leaves and roots, with translocation acropetally through the xylem from the roots and foliage, and accumulation in the apical meristems. Uses Used pre-emergence, at 0.8-2.5 kg/ha, in cotton, sunflowers, peanuts, potatoes, carrots, peas and beans; post-emergence, at 0.8-1.5 kg/ha, in cotton, potatoes, carrots, celery and leeks. Phytotoxicity Used as a directed spray on cotton while young, to avoid foliar injury. Formulation types FW; SC; WP. Selected products: 'Caparol' (USA) (Syngenta); 'Gesagard' (Syngenta); 'Cotton-Pro' (Griffin); 'Efmetryn' (Efthymiadis); 'Prometrex' (Makhteshim-Agan); mixtures: 'Cotralin' (+ alachlor) (Efthymiadis); 'Cottonex Pro' (+ fluometuron) (Aragro)
