However, they were even more devastating for Vietnamese plant life.
George Black explains in The Nation what American invasion meant for Vietnamese natural environment:
"...Although the Romans used to destroy their enemies’ fields, and armies have always bombed and burned adversaries out of their hiding places, there is no real precedent for the systematic use of science and technology to destroy large portions of a country’s natural environment, as the United States did with its herbicide-spraying program in Vietnam. The overall operation was called Trail Dust, but it’s generally referred to as Ranch Hand. Another name that was sometimes used was Hades, and that may be the most apposite of the three...
...Agent Orange accounted for more than 60 percent of the spraying, but actually it was just one in a rainbow spectrum of herbicides, each employing a different cocktail of chemicals and color-coded by a painted band around its fifty-five-gallon storage barrel. Agent White was the second most widely used defoliant, while substantial amounts of Agent Blue were also sprayed, mainly to kill crops by desiccation. Agents Pink, Green and Purple were used in smaller quantities during the early years of the war..."
