Used as a pre-emergence and post-emergence herbicide in agriculture, particularly in crops like soybeans, cotton, and vegetables. It controls a broad spectrum of annual broadleaf and grassy weeds by inhibiting protoporphyrinogen oxidase, an enzyme involved in chlorophyll synthesis. This leads to the accumulation of toxic compounds in plant tissues, causing rapid desiccation and death of susceptible weeds. Effective in low application rates and commonly used in orchards, vineyards, and field crops. Provides residual soil activity, offering extended weed control. Often included in integrated weed management programs to reduce reliance on single-mode-of-action herbicides.
