Used primarily as a selective herbicide in agriculture, especially in the cultivation of onions, garlic, and certain ornamental crops. It controls annual grasses and some broadleaf weeds by inhibiting cell division in root tips, thereby preventing weed establishment. Commonly applied pre-emergence, it is effective in both field and greenhouse settings. Due to its residual activity, it provides extended weed control, reducing the need for frequent applications. Often included in integrated weed management programs where resistance to other herbicides is a concern.
