Plant growth regulators, also known as pesticides, abuse of plant growth regulators can easily cause crop phytotoxicity, affect yield and quality, and increase production costs. In order to avoid phytotoxicity during the use of regulators, the following points must be paid attention to when using plant growth regulators:
1. Do not arbitrarily change the method of use or reuse.
Increase the dosage or concentration of plant growth regulators at will, which will not only not promote plant growth, but will inhibit its growth, so it should be applied at a suitable period in strict accordance with the concentration and interval of the instructions.
2. Do not blindly prepare.
Before using plant growth regulators, carefully read the instructions for use and do not use directly with water. Since some regulators cannot be directly dissolved in water, if the "mother liquor" is not prepared in advance and then prepared to the required concentration, it is difficult to mix the agent at one time, and the use effect will also be affected.
3. It is not possible to substitute medicines for fertilizers.
Plant growth regulators must have sufficient water and fertilizer conditions to play a significant role. If they are used as fertilizers, the hope of promoting crop growth is pinned on plant growth regulators, rather than conventional fertilization, irrigation, cultivating, and loosening soil. Technological efforts will eventually affect the effect of plant growth regulators.
4. Do not mix with other agricultural substances at will
Whether plant growth regulators can be mixed with other substances such as chemical fertilizers and pesticides, do not save trouble for the picture. They are often mixed with chemical fertilizers, pesticides, pesticides, etc. at will. It must be determined after carefully reading the instructions and after testing.
5. Do not use it in the farmland.
Plant growth regulators such as ethephon and gibberellin are used in the reproduction of crops such as vegetables, cotton, and wheat, which can cause increased infertility and a serious reduction in the germination rate of seeds. Therefore, use regulators with caution in reserved crops.
