Four key principles should be followed when using plant growth regulators
Four key principles should be followed when using plant growth regulators:
1. Use appropriate dosages:
Do not arbitrarily increase the dosage. Plant growth regulators are substances with physiological and biological effects similar to plant hormones; they must not be used in excess. Generally, only a few grams or milliliters per *mu* (approx. 0.16 acres) are required. Farmers should not increase the dosage or concentration simply out of concern that a small amount will be ineffective; doing so can inhibit rather than promote growth, and in severe cases, may cause leaf deformity, withering, shedding, or even the death of the entire plant.
2. Do not mix indiscriminately:
Whether a plant growth regulator can be mixed with other substances—such as chemical fertilizers or pesticides—must be determined only after carefully reading the instructions and conducting trials. To save time, many vegetable growers mix them haphazardly with insecticides or fungicides, which can lead to failure in achieving the desired results or cause adverse reactions.
3. Use proper application methods:
Carefully read the instructions before use; do not simply add the regulator directly to water without following the proper procedure. Some regulators do not dissolve directly in water; without first preparing a concentrated stock solution and then diluting it to the required concentration, the agent may not mix evenly, thereby compromising its effectiveness. Therefore, strict adherence to the dilution instructions is essential.
4. Do not substitute regulators for fertilizer:
Plant growth regulators are substances that regulate biological processes; they cannot replace fertilizers, water, or other standard agricultural practices. Even growth-promoting regulators require adequate water and nutrients to function effectively. Excessive spraying under conditions of insufficient water and nutrients can actually be harmful. Consequently, if plants are growing poorly, management practices such as fertilization and irrigation should be prioritized; growth regulators should only be used once these basic needs are met to ensure they work effectively.
Adhering to these principles helps ensure the effectiveness and safety of plant growth regulators and prevents losses caused by improper use.
