Abstract:

Weeds, pests and natural enemies are important biological components in the agricultural ecosystem. At present, the prevention and control of farmland weeds mainly depend on chemical herbicides. However, the long-term unreasonable use of herbicides has seriously affected the ecological balance among farmland weeds, pests and natural enemies. In recent years, the concept of protecting the diversity of farmland weeds and making them play an important role in maintaining the ecological balance of farmland has attracted wide attention. This paper reviewed the research and application technologies of farmland weeds and herbicides on the occurrence of pests and natural enemies on the common weeds in farmland and the use of herbicides, the relationship between weeds, pests and natural enemies, the effects of herbicides on pests and natural enemies, and application of farmland weeds in biological control. This paper aims to use the ecological function of farmland weeds more safely and reasonably, and provide habitat for the protection and utilization of natural enemies and new ideas for the green control of farmland pests.

Key words: farmland ecosystem, weed, pest and natural enemy, integrated pest management, functional plant
