What are the precautions for using plant growth regulators?
Plant growth regulators are a type of pesticide that we use relatively often in our daily lives and that is also fairly common. Using plant growth regulators reasonably can effectively promote crop growth and improve yield and quality. However, when using plant growth regulators, there are also many points that require our attention. So what exactly are they? Below, let's take a look with the editor at the precautions for using plant growth regulators!
1. Pay attention to the dosage
When using growth regulators, we must pay attention to controlling the dosage well and must not increase or decrease it at will. This is because plant growth regulators, like plant hormones, are similar physiological substances and must not be used in excess. Under normal circumstances, only about a few grams are needed per mu. However, many people think that if they use too little, the effect will not be good. So they blindly increase the dosage or concentration. In that case, not only will it fail to help plant growth at all, but it will instead inhibit their growth. In severe cases, phenomena such as leaf deformity, yellowing and leaf drop, or even death of the whole plant may occur.
2. Do not mix at will
When spraying plant growth regulators, many vegetable growers mix them with various chemical fertilizers and pesticides for convenience. In fact, we cannot mix them at will. We should carefully check the instructions and precautions, and only after testing can we determine whether they can be mixed. Otherwise, if mixed blindly, not only will it fail to achieve the purpose of protecting flowers and fruits, but it may also cause pesticide damage as a result. For example, when using ethephon solution, because it is acidic, it must not be mixed with alkaline substances.
3. Pay attention to the method of use
The method of using plant growth regulators also requires a great deal of attention from us. Before use, we must carefully read the instructions and must not directly dilute them with water and apply them to crops. This is because there are many varieties of plant growth regulators, and not all varieties can be diluted with water. Some growth regulators cannot dissolve in water, so they must first be prepared into a stock solution and then adjusted to the required concentration. Otherwise, the solution will not be fully and evenly mixed, causing the efficacy to decline. Therefore, before use, they must be diluted according to the usage procedure.
4. Do not use them as a substitute for fertilizer
Many people think that plant growth regulators can promote crop growth, so after using them they neglect fertilization work. In fact, plant growth regulators cannot be used as a substitute for fertilizer, because growth regulators cannot serve as nutrients for plants. Their main role is to regulate crop growth and they cannot perform the role of fertilizer on crops. Moreover, if water and fertilizer conditions are poor, spraying too much plant growth regulator will also harm their growth. Therefore, if crops are growing poorly, we should first adjust fertilizer and water management well. Only by ensuring fertilizer and water and then reasonably using plant growth regulators can they effectively play their role.
