Herbicides Used During the Vietnam War

During the Vietnam War, the military used herbicides to clear foliage from the jungles and base camps of Vietnam. The heavy foliage provided excellent cover for the enemy. Herbicides were also used to kill crops to diminish the enemy’s food supply. Exposure to these herbicides was later determined to pose a health risk to service members. The following list are the known herbicides and the time frame they were used in Vietnam:


Pink: 1962-1965




Pink-Green Mixture: 1962-1965


Purple: 1962-1965


Blue: 1962-1971


Orange: 1965 and after
