The dosage should be appropriate and cannot be increased at will. Plant growth regulators are substances with similar physiological and biological effects to plant hormones and should not be overused. Generally, the amount per mu is only a few grams or a few milliliters. Some farmers are always afraid that the use of less is not effective, increase the use or use concentration at will, doing so will not only not promote the growth of the plant, but will make its growth is inhibited, serious even lead to leaf deformities, dry fall off, the whole plant died.
Don't mix. Many vegetable farmers in the use of plant growth regulator, in order to save trouble, often at will with chemical fertilizers, pesticides, fungicides, etc. Plant growth regulator, chemical fertilizers, pesticides and other substances can be mixed, must carefully read the instructions and after the test to determine, otherwise not only to promote growth or flowers and fruit, supplement fertilizer, but also due to the improper mixing of pesticides. For example, ethephon is usually acidic and cannot be mixed with alkaline substances. Amine fresh ester meets alkali to decompose easily, cannot mix with alkaline pesticide, chemical fertilizer.
Use it properly. Some vegetable farmers often do not read the instructions carefully before using plant growth regulator, but use the plant growth regulator directly into water. Whether can mix water directly must see clearly, because some plant growth regulator can not be dissolved directly in water, if not prepared in advance into mother liquor and then prepared into the required concentration, it is difficult to mix agents, will affect the use of the effect. Therefore, the use must be strictly diluted in accordance with the instructions.
Growth regulators should not be used in place of fertilizers. Growth regulator is not a plant nutrient, can only play a role in regulating growth, can not replace the use of fertilizer, in the condition of inadequate water and fertilizer conditions, spray too much plant growth regulator is harmful. Therefore, in the discovery of poor plant growth, the first step is to strengthen the fertilization and watering management, on this basis to use the growth regulator can effectively play its role.
Plant growth regulator belongs to pesticide products, product packaging must have the regular "three certificates of pesticide", marked with yellow.
6. Use in strict accordance with the instructions and take protective measures to prevent the impact on human, animal and drinking water safety.
