"Agent Orange is the combination of the code names for Herbicide Orange (HO) and Agent LNX, one of the herbicides and defoliants used by the U.S. military as part of its herbicidal warfare program, Operation Ranch Hand, during the Vietnam War from 1961 to 1971. Vietnam estimates 400,000 people were killed or maimed, and 500,000 children born with birth defects as a result of its use. The Red Cross of Vietnamestimates that up to 1 million people are disabled or have health problems due to Agent Orange.
A 50:50 mixture of 2,4,5-T and 2,4-D, it was manufactured for the U.S. Department of Defense primarily byMonsanto Corporation and Dow Chemical. The 2,4,5-T used to produce Agent Orange was later discovered to be contaminated with 2,3,7,8-tetrachlorodibenzodioxin (TCDD), an extremely toxic dioxin compound. It was given its name from the color of the orange-striped 55 US gallon (208 l) barrels in which it was shipped, and was by far the most widely used of the so-called "Rainbow Herbicides"."
