Problems in the use of pesticides and chemical fertilizers

Pesticides and fertilizers are substances that we need no matter what we grow. It is also the key to ensure the normal growth of crops and improve the yield and quality. However, we need to pay more attention to the use of pesticides and chemical fertilizers, and many people have a lot of problems in their use. So what are the specific ones? The following editor brings you the problems in the use of pesticides and chemical fertilizers, let's have a look!

1. Pursue quick effect

When using pesticides and fertilizers, many people prefer quick-acting ones, because after using quick-acting pesticides and fertilizers, they will have an effect in a short period of time. For example, the content of some foliar fertilizer is mainly nitrogen fertilizer, which can be reduced about three days after spraying. In fact, if the rapid effect is used too much, it will lead to overgrowth, which will affect the development of the crop during the whole growth period. In serious cases, a high level of pesticide residues is still used, resulting in serious excessive pesticide residues in crop products, which is harmful to human health.

2. Chasing after the new and seeking differences

At present, there are many kinds of pesticides and fertilizers in our country, among which there are some "three no products". Because of the fast renewal of pesticides and fertilizers, many people like to use some new pesticides. Take pesticides as an example, although the new pesticides may have a control effect on some pests that are already resistant. But now because there are a lot of pesticides are mainly mixed agents, it is very easy to cause drug damage when it is used. Moreover, some new types of pesticides and fertilizers have not been publicized and promoted, and their effects are not well understood, so it is easy to have all kinds of problems if they are used blindly.

3. Overuse

Excessive use of pesticides and fertilizers is one of the most common problems. Many people blindly pursue yield and constantly apply fertilizer and spray. And when in use, the dose is also far beyond the range requirements. Therefore, it is often easy to lead to drug and fertilizer damage to crops, which is not only not helpful to the growth of crops, but also has a great impact on the yield. In addition, farmers will believe too much in the effects of some fertilizers and pesticides, so as to use a single pesticide fertilizer for a long time, the effect will be worse and worse for a long time.

4. Usage

When we are fertilizing, the use of methods is also very important. The application method of fertilizer will be different according to the different growing period of crops. If it is not used properly, it is easy to cause fertilizer damage to crops. For example, if farm manure that is not fully mature is applied, it is easy to bring harmful gases and bacteria into the field, affecting the growth of crops. When using pesticides, many people do not understand the knowledge of plant protection and fertilizer. Resulting in abnormal crops can not be diagnosed in time, they began to use drugs blindly, which is also very disadvantageous to the growth of crops.

The above is a brief introduction to the problems existing in the use of pesticides and chemical fertilizers. That's all for today's introduction. This article is for reference only. I hope it can help you all.
