Used as a selective herbicide in agriculture, particularly in corn (maize) crops. It controls a broad spectrum of annual grasses and broadleaf weeds by inhibiting the enzyme HPPD (4-hydroxyphenylpyruvate dioxygenase), which is essential for plant pigment formation. This leads to chlorophyll degradation and plant death. Applied pre-emergence or early post-emergence, it provides residual soil activity, offering extended weed control. Due to its systemic action, it is effective at low application rates and is often used in combination with other herbicides to enhance spectrum and manage resistance.
