Toxic chemical defoliant [that strips trees and plants of their leaves] used by American military in Vietnam to deprive the enemy of food and of hiding places in the jungles, by killing all vegetation.
Nicknamed “Agent Orange” because of the identifying orange stripe on its steel drum containers. It was sprayed over large areas by aircraft and over smaller areas by hand. It was supposed to have been diluted 20:1, but it was used full strength. Many Vietnam Veterans suffer from health problems caused by exposure to Agent Orange.
