DA-6+Ethephon,It is a compound dwarfing, robust, and anti-lodging regulator for corn. Using Ethephon alone shows dwarfing effects, wider leaves, dark green leaves, upward leaves, and more secondary roots, but leaves are prone to premature aging. The use of DA-6+Ethephon compound agent for corn to control vigorous growth can reduce the number of plants by up to 20% compared with using Ethephon alone, and has obvious effects of increasing efficiency and preventing premature aging.

S-Abscisic Acid (ABA) is a plant hormone. S-Abscisic Acid is a natural plant growth regulator that can promote coordinated plant growth, improve plant growth quality, and promote plant leaf shedding. In agricultural production, Abscisic Acid is mainly used to activate the plant's own resistance or adaptation mechanism to adversity, such as improving the plant's drought resistance, cold resistance, disease resistance, and salt-alkali resistance.

4-Chlorophenoxyacetic acid (4-CPA) is a phenolic plant growth regulator. 4-Chlorophenoxyacetic acid (4-CPA) can be absorbed by the roots, stems, leaves, flowers, and fruits of plants. Its biological activity lasts for a long time. Its physiological effects are similar to endogenous hormones, stimulating cell division and tissue differentiation, stimulating ovary expansion, inducing parthenocarpy, forming seedless fruits, and promoting fruit setting and fruit expansion.
