Ametryn is a selective systemic herbicide, absorbed by the roots and leaves, with translocation acropetally through the xylem, and accumulation in the apical meristems. Used to pre- and post-emergence control of most annual grasses and broad-leaved weeds in pineapples, augar cane, bananas, citrus fruit, maize, cassava, coffee, tea, sisal, cocoa, oil palms, and on non-crop land. Application rates are in the range 2-4 kg/ha except when used as a directed spray on maize. Also used as a potato haulm desiccant.
