During the war in Vietnam, the US tested agents orange, blue, and purple at CFB Gagetown. A 1968 U.S. Army memorandum titled “defoliation tests in 1966 at base Gagetown, New Brunswick, Canada” explained: “The department of the army, Fort Detrick, Maryland, has been charged with finding effective chemical agents that will cause rapid defoliation of woody and Herbaceous vegetation. To further develop these objectives, large areas similar in density to those of interest in South East Asia were needed. In March 1965, the Canadian ministry of defense offered Crops Division large areas of densely forested land for experimental tests of defoliant chemicals. This land, located at Canadian forces base Gagetown, Oromocto, New Brunswick, was suitable in size and density and was free from hazards and adjacent cropland. The test site selected contained a mixture of conifers and deciduous broad leaf species in a dense undisturbed forest cover that would provide similar vegetation densities to those of temperate and tropical areas such as South East Asia.”
