What common mistakes are made when using plant regulators?

Plant growth regulators are organic compounds that are artificially synthesized (or naturally extracted from microorganisms) and have growth and development regulating effects similar to natural plant hormones.What common mistakes are made when using plant regulators?

I. Introduction to the use of plant regulators

Plant growth regulators are substances that people, after understanding the structure and mechanism of action of natural plant hormones, artificially synthesize to have physiological and biological effects similar to plant hormones. They are used in agricultural production to effectively regulate the growth and development process of crops, achieving goals such as stable and increased yield, improved quality, and enhanced crop stress resistance.

Plant growth regulators are chemically synthesized substances that regulate plant growth and development, as well as natural plant hormones extracted from organisms. They are called plant growth regulators. Common plant growth regulators include fast-acting diethyl aminoethyl hexanoate (DA-6), forchlorfenuron, sodium nitrophenolate, brassinosteroid, and gibberellin.

II. What common mistakes are made when using plant regulators?

1. No longer using fertilizer after applying plant regulators

Plant growth regulators can only exert significant effects under conditions of sufficient water and fertilizer. However, some plant growth regulators have their effects exaggerated by manufacturers, causing some farmers to use them as fertilizer and pin their hopes for promoting crop growth on plant growth regulators, rather than putting effort into conventional techniques such as fertilization, irrigation, intertillage, and soil loosening, which ultimately affects the effectiveness of the plant growth regulators.

2. Using them randomly without regard to the specific conditions of plant growth

Plant growth regulators must be used at key moments in plant growth to exert their maximum effect. If the timing of use is inappropriate, ideal results cannot be achieved, and “side effects” may even occur. Some farmers lack sufficient understanding of this, believing that spraying plant growth regulators at any time can promote growth, increase yield, and increase income. Therefore, they spray at any time without considering the timing, resulting in poor spraying results, and in some cases even reduced yield and income.

3. Using the wrong dosage

Plant growth regulators are hormone-type substances, and generally only a few grams or a few milliliters are needed per mu. However, some farmers always worry that a smaller dosage will have no effect and arbitrarily increase the dosage or concentration of the plant growth regulator. This not only fails to promote plant growth, but instead inhibits it, and in severe cases can even lead to leaf deformity, drying and shedding, and death of the entire plant.

4. Mixing with other drugs and fertilizers

Whether plant growth regulators can be mixed with chemical fertilizers, pesticides, and other substances must be determined only after carefully reading the instructions and conducting tests. However, many farmers, when using plant growth regulators, often mix them arbitrarily with chemical fertilizers, insecticides, fungicides, and the like to save trouble, hoping to simultaneously promote growth or preserve flowers and fruits, supplement fertilizer, or prevent diseases and pests. But if mixed improperly, it will yield “half the result with twice the effort,” or even “all work and no gain.”

5. Not following the instructions for use

For example, a certain gibberellin widely used in production must first be dissolved with alcohol or warm high-proof baijiu before it can be mixed with water for use. However, some farmers, before using plant growth regulators, often do not carefully read the instructions for use, but instead directly mix the plant growth regulator with water. Because some plant growth regulators cannot dissolve directly in water, and because a trace amount of plant growth regulator, if not first prepared into a “mother liquor” and then diluted to the required concentration, is difficult to mix evenly in one go, this also affects the effectiveness of use.
