包埋技术在植物精油类生物农药控释中的应用

In order to control pests and diseases and increase grain yield, pesticides are widely used in modern agriculture. However, the irrational use of chemical pesticides has caused many problems, such as soil water pollution and pesticide residues in products, which are contrary to the national sustainable development strategy. Therefore, the development of safe and non-toxic biopesticides has become an inevitable trend, in which the effective components of botanical pesticides come from plants, which have the advantages of non-toxicity, green and easy degradation. As a new biopesticides, it has become a research hotspot. However, the active ingredients of botanical pesticides are mostly plant essential oils, which have some pain points such as insolubility in water, instability and poor efficacy. In this paper, the research progress of the application of embedding technology in the controlled release of plant essential oil pesticides by researchers at home and abroad in recent years is described. The technology and mechanism of embedding plant essential oil with alginate, chitosan and cyclodextrin were introduced and analyzed. The application prospect of embedding technology in the field of plant essential oil biopesticides was also prospected.
