Terbuthylazine APPLICATIONS
Biochemistry Photosynthetic electron transport inhibitor at the photosystem II receptor site. Maize tolerance of triazines is attributed to conjugation with glutathione. Mode of action Herbicide, absorbed mainly by the roots. Uses Broad-spectrum pre- or post-emergence weed control in maize, sorghum, vines, fruit trees, citrus, coffee, oil palm, cocoa, olives, potatoes, peas, beans, sugar cane, rubber, and in forestry in tree nurseries and new plantings. It remains largely in the topsoil, controlling a wide range of weeds, at rates of 0.6-3 kg a.i./ha; high rates are only recommended as band applications. Phytotoxicity Phytotoxic to many annual plants and to aquatic plants. Formulation types SC; WG.
