1. Economic benefits. Insect control net coverage can realize no or less pesticide application in vegetable production, thus saving medicine, labor and cost. Although the use of insect prevention net increases the production cost, because of its long service life (4-6 years), long use time (5-10 months) in the year, and can be used for multiple crops (6-8 crops can be produced by planting leafy vegetables), the input cost of each crop is low (the effect is more obvious in disaster years). Good quality (no or less pesticide pollution) and good yield increase effect.
2. Social benefits. It has greatly improved the pest prevention and disaster resistance of vegetables in summer and autumn, and solved the problem of vegetable shortage that has plagued vegetable farmers and citizens for a long time. Its benefits are self-evident.
3. Ecological benefits. Environmental problems have been paid more and more attention. Chemical pesticides have significant control effects, but they expose many drawbacks. The frequent use of pesticides has caused the pollution of soil, water and vegetables. Every year, poisoning occurs due to the accidental consumption of pesticide contaminated fruits and vegetables; Insect resistance has been enhanced, and the control is becoming more and more difficult. The diamondback moth, Spodoptera litura and other pests have even developed to the point where there is no medicine to cure. And the purpose of pest control is achieved through physical control.
