Currently, the main plant growth regulators used in vegetable production include 1-Naphthyl Acetic Acid (NAA), Indole Acetic Acid (IAA), Gibberellic Acid (GA3), Chlormequat Chloride (CCC), methyl naphthaleneacetate, quinacrine, Ethephon, Paclobutrazol (Paclo), and B9.

Prohexadione calcium is a plant growth retardant/inhibitor. Its core function is to inhibit gibberellin biosynthesis, thereby Controlling excessive vegetative growth of the above-ground parts (stems and leaves), resulting in shorter, sturdier plants with shorter internodes.

Diethyl aminoethyl hexanoate DA-6 is a plant growth regulator primarily used to promote crop growth, increase yield, and improve quality. The following describes its specific application methods for potatoes, sweet potatoes, and ginger during their tuber expansion phase.

Paclobutrazol is Most commonly used and most effective,It is a gibberellic acid synthesis inhibitor. It inhibits longitudinal cell elongation, shortening internodes, resulting in a shorter and more robust plant, thicker leaves, and darker leaf color.
