  • Applications

    Chlormequat Chloride is used primarily as a plant growth regulator to reduce plant height and improve lodging resistance in cereals such as wheat, barley, and rice, typically applied as a foliar spray; in horticulture, it is employed to control size and form of ornamental crops and nursery stock, helping with landscaping and production efficiency; it is also used as a research tool in plant growth regulation studies to investigate gibberellin pathways and to support optimization of agricultural practices. Use is subject to local regulations and formulation limits.
