Agent Green is the code name for a powerful herbicide and defoliant used by the U.S. military in its Herbicidal Warfare program during the Vietnam War. The name comes from the green stripe painted on the barrels to identify the contents. It was one of the so-called "rainbow herbicides" that included the more infamous Agent Orange. Agent Green was only used between 1962 and 1964, during the early "testing" stages of the spraying program.
Agent Green's only active ingredient was 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), one of the common phenoxy herbicides of the era. It was later learned that a dioxin, 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD), is produced as a side effect of the manufacture of 2,4,5-T, and was thus present in any of the herbicides that used it. Owing to Agent Green's consisting entirely of 2,4,5-T, along with the similar Agent Pink, it contained many times the level of dioxin found in Agent Orange.
During much of the fighting in the Vietnam War, chemical agents were used by the United States to defoliate the landscape. Although many different chemical agents were used, the most well known today is “Agent Orange,” one of the “Rainbow Herbicides.”
