Cacodylic acid (AsOH(CH<sub>3</sub>)<sub>2</sub>), an organic form of arsenic, is a defoliant and was used in the Vietnam War under the name Agent Blue. In the United States, it is sometimes sprayed on cotton fields, where it causes the plants to desiccate, making harvesting of cotton bolls easier. Cacodylic acid is also the primary excreted metabolic product of arsenic in humans. | Cacodylic acid (AsOH(CH<sub>3</sub>)<sub>2</sub>), an organic form of arsenic, is a defoliant and was used in the Vietnam War under the name Agent Blue.
