Used as a selective herbicide in agriculture, particularly for controlling broadleaf weeds and some grassy weeds in crops like corn, sugarcane, and pineapple. It works by inhibiting photosynthesis in susceptible plants, leading to their eventual death. Applied pre-emergence or early post-emergence, it is effective in reducing weed competition, thereby improving crop yield. Due to its persistence in soil and potential for groundwater contamination, its use is restricted or discontinued in many regions. Often applied as part of integrated weed management programs where residual control is needed.
