  • Applications

    Prohexadione calcium (CAS 127277-53-6) is a plant growth regulator used broadly to suppress vegetative growth in a range of crops by inhibiting gibberellin biosynthesis. In practice, it is applied in agriculture and horticulture to manage growth in fruit crops, cereals, and ornamentals, including greenhouse settings, by reducing canopy height and improving manageability. Common use cases include: (1) field crops to limit vegetative expansion; (2) fruit crops to reduce height and facilitate pruning and harvest; (3) ornamentals and container-grown plants for height control and shape maintenance; (4) cereals and small grains to reduce lodging; (5) turf and golf course management to lower mowing frequency and maintain desirable leaf density. Applications are typically delivered as a foliar spray, with local regulations and formulation limits governing use.
