  • Applications

    Fluazifop-p-butyl (CAS 79241-46-6) is a selective grass herbicide in the aryloxyphenoxypropionate class, used in agriculture to control grasses in key crops such as soybeans, cotton, and peanuts. Real-world applications include: controlling grassy weeds in major crop systems; managing grasses in vegetables, fruits, and specialty crops; serving as the active ingredient in herbicide formulations (e.g., emulsifiable concentrates and water-dispersible granules) for pre- and post-emergence applications; integration into integrated weed management programs and tank-mix strategies with other herbicides; and supporting research and development to evaluate efficacy, crop safety, and environmental residues.
