Used as a selective herbicide in agriculture, particularly for controlling grass weeds in broadleaf crops such as soybeans, cotton, and vegetables. It works by inhibiting acetyl-CoA carboxylase, an enzyme essential for fatty acid synthesis in grasses, leading to growth cessation and plant death. Applied post-emergence, it effectively manages both annual and perennial grasses while showing minimal impact on the broadleaf crops it protects. Commonly formulated as the butyl ester for improved leaf penetration and rainfastness.
