Used as a selective herbicide in agriculture, particularly in sugar beet cultivation, to control broadleaf weeds and some grass species. It works by inhibiting photosynthesis in susceptible plants, leading to their rapid decline. Commonly applied pre-emergence or early post-emergence, it provides effective weed management while allowing crop tolerance due to selective metabolism. Often found in combination with other herbicides to broaden the spectrum of weed control. Its deuterated form (D13) is primarily used in analytical laboratories as an internal standard for residue testing and metabolic studies, ensuring accurate quantification in environmental and biological samples.
