    APPLICATIONGS
    Photosynthetic electron transport inhibitor at the photosystem II receptor site. Maize tolerance of triazines is attributed to conjugation with glutathione. Biochemistry
    Herbicide, absorbed mainly by the roots. Mode of action
    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/ha; high rates are only recommended as band applications. In Europe, used mainly on maize and sorghum with a maximum application rate of 1.5 kg/ha, mainly in mixture with other herbicides. Uses
