The use of plant growth regulators
1. The dosage should be appropriate, and the dosage should not be increased arbitrarily. Plant growth regulators are a class of substances that have similar physiological and biological effects to plant hormones and should not be used in excess. Generally, the dosage per mu is only a few grams or a few milliliters. Some farmers are always afraid that the dosage will not be effective, so they increase the dosage or concentration at will. This will not only fail to promote plant growth, but will inhibit its growth, and even lead to leaf deformity, dryness and shedding, and the death of the entire plant.
2. Do not mix at will. When using plant growth regulators, many vegetable farmers often mix them with chemical fertilizers, pesticides, fungicides, etc. at will to save trouble. Whether plant growth regulators can be mixed with chemical fertilizers, pesticides and other substances must be determined after careful reading of the instructions for use and tests. Poisoning occurs. For example, ethephon is usually acidic and cannot be mixed with alkaline substances; diethyl aminoethyl hexanoate is easily decomposed in the presence of alkali and cannot be mixed with alkaline pesticides and fertilizers [2]
3. Use the method properly. Before using plant growth regulators, some vegetable farmers often do not read the instructions carefully, but use the plant growth regulators directly with water. Whether it can be directly mixed with water must be seen clearly, because some plant growth regulators cannot be dissolved in water directly. Therefore, when using, be sure to dilute in strict accordance with the instructions for use.
4. Growth regulators cannot replace fertilizer application. Growth regulators are not plant nutrients, they can only regulate growth and cannot be used as a substitute for fertilizers. In the case of insufficient water and fertilizer conditions, spraying too much plant growth regulators is harmful. Therefore, when poor plant growth is found, management such as fertilization and watering should be strengthened first, and growth regulators can be used on this basis to effectively play their role.
5. Plant growth regulators are pesticide products, and the product packaging must have the formal "Three Pesticide Certificates", and the labeling band is yellow.
6. Use in strict accordance with the instructions, and take protective measures to prevent the impact on the safety of people, animals and drinking water.
