This type of foliar fertilizer contains substances that regulate plant growth, such as auxin, hormones and other ingredients.
Its main function is to regulate plant growth and development. It is suitable for use in the early and middle stages of plant growth.

During the growth process, plants can not only synthesize many nutrients and structural substances, but also produce some physiologically active substances, called endogenous plant hormones. Although these hormones are present in small amounts in plants, they can regulate and control the normal growth and development of plants, such as cell growth and differentiation, cell division, organ construction, dormancy and germination, plant tropism, sensitivity, maturity, shedding, aging, etc., all of which are directly or indirectly regulated by hormones. Some organic substances artificially synthesized in factories that have similar molecular structures and physiological effects to natural plant hormones are called plant growth regulators.
Plant growth regulators and plant hormones are generally collectively referred to as plant growth regulators.

At present, the commonly used plant growth regulators in production are 
①Auxin: such as Naphthalene acetic acid (NAA), Indole-3-acetic acid, anti-drop agent, 2,4-D, etc.; 
②Gibberellic Acid: There are many types of Gibberellic Acid compounds, but the Gibberellic Acid used in production is mainly (GA3) and GA4, GA7, etc.; 
③Cytokinins: such as 5406;
④Ethylene: Ethephon; 
⑤Plant growth inhibitors or retardants: Chlormequat Chloride (CCC), chlorambucil, Paclobutrazol (Paclo), plastic, etc. In addition to the above, there are Brassinolide (BRs), zeati, abscisic acid, defoliants, triacontanol, etc.
