A broad-leaf herbicide, now banned for use in the United States. Its full name is 2,4,5-trichlorophenoxyacetic acid. After postemergence treatment it is readily absorbed by foliage and roots and translocated throughout the plant. This herbicide gained much notoriety during and after the Vietnam War because it was a component in the defoliant Agent Orange, which has been implicated in cancer occurrence in some war veterans. The carcinogen 2,3,7,8-TCDD is formed as a byproduct in the manufacture of 2,4,5-T. The Environmental Protection Agency (EPA) restricted the use of 2,4,5-T in 1971, and suspended usage in 1979 following concerns that it caused miscarriages in women living in areas where application of 2,4,5-T had occurred.
