The vegetable growing industry is an important civilian production industry. In recent years, with the growing scale of vegetable cultivation, the variety of cultivation styles, the variety of pests in vegetable fields is increasing, the frequency of insect pests is increasing, and the cultivation of vegetables is increasing. The hazards of the industry are also growing. In order to solve the problem of vegetable field pests, while ensuring the development of green ecology and ensuring the quality and safety of agricultural products such as vegetables, the green prevention and control technology of insecticidal lamps is used in vegetable fields. It uses insecticidal lamp to kill insects, has the advantages of high efficiency, green, simple operation, and no resistance to pests. After application, it can significantly reduce the density of insects, reduce the use of pesticides and environmental pollution, improve the quality of agricultural products, and achieve the goal of increasing production and quality.
Common pests in vegetable fields include Plutella xylostella, Spodoptera exigua, Spodoptera litura, Melon, Little Wood Tiger, Chafer, Bean Wild, and Tobacco, and insecticidal lamps have a strong trapping effect on these vegetable pests. Especially for Plutella xylostella, Spodoptera exigua, etc., which have higher levels of drug resistance, if pesticides are used to kill insects, because these pests are resistant to insecticides, the insecticidal effect will become worse and worse, and insecticidal lamps will be used for prevention and control. The effect is good, and the side effects are small, which brings safer and more reliable green prevention and control technology for vegetable field pest control.
In recent years, the green prevention and control technology brought about by insecticidal lamps has been highly praised and has become a key technology for green pest control of vegetable pests. It has applications in the production of open vegetables and facility vegetables. According to the test, every lamp in the general vegetable field can trap about 2,000 pests per day. It is the physical insecticide that has the most insecticidal species and the best insecticidal effect. The effective control area of ​​each insecticidal lamp can reach 60 mu, and the input cost per mu is low. Generally speaking, an investment can be used continuously for 5 to 6 years. In addition, after application, it can effectively reduce pesticide expenditure, and has obvious effects of reducing drugs and controlling diseases, and has extremely high economic and social benefits. And this green prevention and control technology should be vigorously promoted and applied in modern agricultural production.
