What are the application effects of insect nets?

Application effect

① Economic benefits. Insect-proof net coverage can realize the production of vegetables without spraying or less spraying, thus saving medicine, labor and cost. Although the use of insect nets increases the production cost, because the insect nets have a long service life (4-6 years), a long use time (5-10 months) in the year, and can be used in multiple crops (6-8 crops can be produced by planting leafy vegetables), the input cost per crop is low (the effect is more obvious in disaster years). Good vegetable quality (no or less pesticide pollution), good yield increase effect.

② Social benefits. Greatly improve the pest prevention and disaster resistance of summer and autumn vegetables, solve the problem of vegetable shortage that has plagued leaders at all levels for a long time, vegetable farmers and citizens, and its social effect is self-evident. 

③ Ecological benefits. Environmental problems have attracted more and more people's attention. The effect of chemical pesticides is remarkable, but many drawbacks are exposed. The frequent use of pesticides has caused the pollution of soil, water and vegetables, and poisoning incidents have occurred every year due to eating vegetables contaminated by pesticides. The resistance of pests is increasing, and the prevention and control is becoming more and more difficult, and the pests such as Diamondiella moth and Noctura terrestris even develop to the point of no medicine. The purpose of insect control is achieved through physical control.
