One can provide non-polluting vegetables:
Most of the vegetables are edible parts. The roots, leaves, flowers and fruits are rich in nutrients and vitamins. They are often eaten directly without processing. Therefore, people are very concerned about the pesticide pollution of vegetables. If biological control techniques are applied to control vegetable pests. It can avoid pesticide pollution and ensure the safety of humans and animals.
The second is to avoid the resistance of vegetable pests:
In the case of many vegetable pests, vegetable farmers use chemical pesticides for prevention and control. Over time, drug resistance is produced. Farmers often have to increase the amount of pesticides and increase the number of pesticides. The more pesticides are used, the more insects The more healing the vicious circle, the increased resistance of pests and the decline in chemical control. Biological control through biological and its products, can effectively control vegetable pests, ensure the high quality and high yield of non-polluting vegetables, reduce the input of organic pesticides, and fundamentally remove the selection pressure of chemical pesticides for controlling pests in vegetable fields, thus eliminating pests. The hotbed of drug resistance effectively reverses the vicious cycle of chemical pesticide abuse into a virtuous cycle.
Third, protect the environment
The environmental pollution of chemical pesticides has become a common concern of all countries in the world. Once some pesticides enter the field, they will degrade after several years, ten years or even more than half a century. Chemical pesticides seriously damage people's health and even affect the happiness of future generations. Control of vegetable worms often requires large and multiple spraying of chemical pesticides. This not only pollutes vegetables, but also inevitably causes pollution of surrounding weather, soil and waters, destroys ecological balance, and worsens people's living environment. The application of biotechnology to control vegetable pests will not cause environmental pollution and can provide people with a clean and pollution-free living space.
