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.

Scientifically controlling growth is key to high-quality potato yields. Chemical agents such as Paclobutrazol (Paclo) and Uniconazole, combined with agronomic measures, precisely control growth from the budding to early flowering stage to effectively inhibit excessive growth and promote tuber enlargement, thereby increasing yield and income.
