From Wikipedia, the free encyclopedia

Four-plane defoliant run, part of Operation Ranch Hand

Operation Ranch Hand was a U.S. Military operation during part of the Vietnam War, lasting from 1962 until 1971. It involved spraying an estimated 12 million + US gallons of defoliants over rural areas of South Vietnam in an attempt to deprive the Viet Cong of vegetation cover and food, in possible violation of the Geneva Conventions.[1][2]



For Operation Ranch Hand corporations like Dow Chemical Company and Monsanto Company were given the task of developing the following herbicides for this purpose:

The defoliant used in the largest quantity was Agent Orange, a mixture of herbicides now known to have been contaminated with dioxin. About 12 million gallons of Agent Orange and other chemicals were sprayed over Southeast Asia during American combat operations.[3]

In 2005, the New Zealand government confirmed that it supplied Agent Orange chemicals to the United States military during the conflict. Since the early 1960s, and up until 1987, it manufactured the 2,4,5T herbicide at a plant in New Plymouth, which was then shipped to U.S. military bases in South East Asia.[4][5][6]


A prime area of Ranch Hand operations was in the Mekong Delta, where the U.S. Navy patrol boats were vulnerable to attack from the undergrowth at the water's edge. Operation Ranch Hand was concluded May 1971 at Bien Hoa AB, RVN.
