Used as a selective herbicide in corn crops to control a broad spectrum of broadleaf and grassy weeds. It works by inhibiting the enzyme HPPD (4-hydroxyphenylpyruvate dioxygenase), which is essential for carotenoid biosynthesis in plants. This inhibition leads to the breakdown of chlorophyll and plant death due to photo-oxidative damage. Effective at low application rates, it provides pre- and post-emergence weed control, particularly against resistant weed species such as glyphosate-resistant weeds. Its selectivity allows safe use in tolerant corn varieties while minimizing impact on the crop.
