Trifluralin is a common pre-emergent selective herbicide, a dinitroaniline. With about 14 million pounds (6,400 t) used in the United States in 2001, and 3–7 million pounds (1,400–3,200 t) in 2012, it is one of the most widely used herbicides. Trifluralin is also used in Australia, New Zealand, Brazil and previously in the EU. Introduced in 1964, Trifluralin was the first organofluorine compound used as an agrochemical.

Trifluralin is generally applied to the soil to control annual grass and broadleaf weed species. It inhibits root development by interrupting mitosis and controls weeds as they germinate. Trifluralin moves very little inside the plant, remaining in the roots.
