  • Applications

    Gibberellic acid (CAS 77-06-5) is a plant growth regulator used mainly in agriculture and horticulture to modulate development in crops and ornamentals. Typical applications include breaking seed and bulb dormancy and promoting germination; stimulating stem elongation and vegetative growth in young plants; enhancing flowering and fruit set in certain crops; increasing fruit size and uniformity, notably in grape production; and supporting propagation programs in nurseries through improved germination and seedling vigor. It is applied under label directions and remains subject to local regulations and formulation limits.
