Etymology: < agent n.¹ + orange adj.¹ The substance was so named after the colour coding on the drums containing it.

A defoliant and herbicide used by the United States during the Vietnam War to remove forest cover and destroy crops. Cf. agent n.¹ and adj. Compounds 1.Agent Orange is a 50:50 mixture of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) and 2,4-dicholorophenoxyacetic acid (2,4-D).It was one of a number of herbicides used by the U.S. military in South-East Asia between 1962 and 1971, and became notorious for causing death and injury on a wide scale and for giving rise to birth defects. Its extreme toxicity was attributed to contamination of the 2,4,5-T component with a dioxin (2,3,7,8-tetrachlorodibenzodioxin).
