Beflubutamid is a selective contact herbicide used in agriculture, primarily for controlling broadleaf weeds and some grasses in cereal crops such as wheat, barley, and rice. It functions as a protoporphyrinogen oxidase (PPO) inhibitor, which disrupts porphyrin biosynthesis, leading to the accumulation of phototoxic protoporphyrin IX, membrane damage, lipid peroxidation, and rapid necrosis of treated weeds. Effective in pre-emergence and early post-emergence applications, it offers good crop selectivity while minimizing impact on cereals. Beflubutamid is commonly tank-mixed with other herbicides to expand weed control spectrum and mitigate resistance risks in integrated weed management programs.
