  • Applications

    Glufosinate-ammonium is primarily used as the active ingredient in non-selective herbicides to control weed species in agriculture, including fields, orchards, and other non-crop areas. It is commercially formulated into herbicide products in multiple forms such as emulsifiable concentrates and water-dispersible granules. In crop protection programs, it supports integrated weed management and resistance management through effective post-emergence control across a broad spectrum of weeds. It is involved in formulation development and product stewardship, including quality control to ensure consistency of the final herbicide products. In research and development, it is used to study herbicide chemistry, environmental fate, and regulatory aspects to support product registration and ongoing formulation optimization.
