1. The dosage should be appropriate and cannot be increased at will. Plant growth regulator is a kind of substance which has similar physiological and biological effects with plant hormone. Generally each mu dosage only needs a few grams or a few milliliters. Some farmers are always afraid of less dosage has no effect, arbitrarily increase dosage or use concentration, so that not only cannot promote plant growth, but will make its growth inhibited, and even seriously lead to leaf deformity, dry off, the whole plant died.
2. Don't mix it up. When many vegetable farmers use plant growth regulators, they often mix them with chemical fertilizers, insecticides and fungicides to save time. Whether plant growth regulator can be mixed with chemical fertilizers, pesticides and other substances must be determined after careful reading of the instructions and through tests. Otherwise, the effects of promoting growth, preserving flowers and fruits, and supplementing fertilizers will not be achieved, but drug damages will occur due to improper mixing. For example, ethephon is usually acidic and cannot be mixed with alkaline substances. Amines are easy to decompose when exposed to alkali and cannot be mixed with alkaline pesticides and chemical fertilizers
3. Use it properly. Before using the plant growth regulator, some vegetable farmers often do not read the instructions carefully, but use the plant growth regulator directly mixed with water. Whether can directly add water must see clearly, because some plant growth regulator can not be directly dissolved in water, if not prepared in advance into the mother liquor and then prepared into the required concentration, it is difficult to mix pharmaceutical, will affect the use effect. Therefore, be sure to dilute in strict accordance with the instructions.
4. Growth regulators should not be used in place of fertilizer. Growth regulators are not plant nutrients and can only play a role in regulating growth and cannot replace fertilizer. In the case of insufficient water and fertilizer conditions, excessive spraying of plant growth regulators will be harmful. Therefore, when plant growth is found to be poor, management such as fertilization and watering should be strengthened first, and only on this basis can growth regulator be used to play its role effectively.
5. Plant growth regulators belong to the pesticide category, and the product package must have normal "pesticide Certificate 3" with yellow label.
6. Use in strict accordance with the instructions and take protective measures to prevent any impact on the safety of human, livestock and drinking water.
