Introduction To Plant Growth Regulators

Plant growth regulators are a class of substances that have similar physiological and biological effects to plant hormones. Substances that have been found to regulate plant growth and development include aminoethyl ester (DA-6), chlorfenapyr, sodium nitrophenolate, auxin, gibberellin, ethylene, cytokinin, abscisic acid, brassinolide, salicylic acid, jasmonic acid, paclobutrazol and polyamines, and the first nine categories are mainly used as plant growth regulators in agricultural production.
According to the dosage, period and method of use indicated on the registration and approval label, the use of plant growth regulators generally does not cause harm to human health. If there is irregular use, it may cause crops to grow too fast, or inhibit growth, or even die. It will have a certain impact on the quality of agricultural products and cause harm to human health. For example, green freshness (germination inhibition) that can prolong the storage period of potatoes, garlic and onions has a carcinogenic effect. Chinese law prohibits the sale and use of plant growth regulators that have not been approved by relevant national or provincial departments.
