Fomesafen（Cat No.:R069449）is a diphenyl ether herbicide widely used for post-emergence weed control in soybean, cotton, and other broadleaf crops. It acts by inhibiting protoporphyrinogen oxidase (PPO), an essential enzyme in chlorophyll biosynthesis, leading to membrane disruption and cell death in susceptible plants. Fomesafen shows high selectivity, effectively targeting broadleaf weeds while sparing crops when applied properly. In research, it is used to study herbicide resistance, PPO enzyme function, and plant stress responses. Its persistence and environmental behavior also make it important in ecological and agricultural chemistry studies.
