Used as a pre-emergence and post-emergence herbicide in agriculture, particularly in orchards, vineyards, and soybean fields to control broadleaf weeds and some grassy weeds. It works by inhibiting protoporphyrinogen oxidase (PPO), an enzyme essential for chlorophyll synthesis, leading to the accumulation of toxic compounds in plant cells upon exposure to light. Effective against resistant weed species, it is often applied as a soil treatment before weed emergence or as a directed spray to avoid crop damage. Its residual activity provides extended weed control, reducing the need for frequent applications. Commonly used in integrated weed management programs due to its fast action and compatibility with certain crop protection systems.
