Light micrograph (LM) of 2,4-D (herbicide) crystals. 2,4-D (2,4-dichlorophenoxyacetic acid) is a common systemic herbicide used in the control of broadleaf weeds. It is the most widely used herbicide in the world. 2,4-D was introduced in 1946, when it was the first commercially successful selective herbicide. It allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crops. 2,4-D is sold in various formulations under a wide variety of brand names. It continues to be used because of its low cost despite the availability of more selective, more effective, safer products. Commercial formulations used today use the trimethylamine salt or one of several esters. The amine salt formulations can cause irreversible eye damage.
