With the advancement of modern bioengineering technology and the improvement of the commercial production level of biological products, bio-pesticides have been more and more widely used in agricultural production in recent years, and have received good results. However, many farmers have a vague understanding of biological pesticides .

Some people think that after the application of biological pesticides, chemical pesticides can be used, or the era of chemical pesticides is over, and biological pesticides are opposed to chemical pesticides. Some people think that foods that do not use biological pesticides cannot be called pollution-free foods. One-sided emphasis on the role of biological pesticides; some believe that bio-pesticide is good, that is, slow effect, poor visual effect, leaving an ineffective impression to farmers eager to prevent pests and diseases; some farmers will be efficient in biological agents

Mix with fungicides or acidic compound solutions to lose control. All of these hinder the healthy and orderly application of bio-pesticide. Therefore, there should be a comprehensive understanding of bio-pesticides and the correct use of technology.

First, we should see the advancement of biological pesticides

There are many contents of biological pesticides, including microbial pesticides, biochemical pesticides, genetically modified organism pesticides, natural enemy biological pesticides, and plant-derived pesticides. The application of biological pesticides can kill a variety of pests and diseases, and can produce pollution-free green foods. Third, it can reduce environmental pollution, ensure the safety of humans and animals, and protect natural enemies. Fifth, pests and diseases are not easy to produce resistance. However, bio-pesticide is only one of the pesticide components, and it is not yet a substitute for chemical pesticides.

Second, understand the mechanism of action of biological pesticides

Biological pesticides have a gradual process of poisoning pests and diseases. Such as high-efficiency Bt, first numb the pest nerve, and then destroy its internal organs to death, it takes 1 to 3 days. Another example is the insect virus, which is the nucleic acid of the virion that enters the pest and absorbs the nutrients in the insect body, causing the cell tissue to disintegrate and die, which takes 3 to 5 days. Although the visual effect of biological pesticides is slower than that of chemical pesticides, the harmful functions of pests and diseases have been suppressed after application, or they exist in name only. Therefore, it must be rationally applied according to the characteristics of these pesticides.

Third, the correct application of biological pesticides

1. Strictly apply the biological pesticides a few days in advance according to the forecast of pests and diseases in the local plant protection department.

2, to strictly follow the dosage of the drug, can not increase or decrease the concentration of application.

3. In order to improve the control effect and safety performance, it can be mixed with some low-toxic chemical pesticides to minimize the pollution of high-toxic pesticides. However, high-efficiency BT is prohibited from being mixed with fungicides and acidic compounding liquids, and cannot be applied in mulberry gardens.

4. Cannot expose or damp biological pesticides.

5, choose to use the medicine on a sunny afternoon or cloudy, after the medicine, it must be re-sprayed once in the rain.
