摘要
农药的不科学使用容易引发一系列生态环境安全问题,严重制约着我国农业的可持续发展。纳米科技的长足进步推动了现代植物保护学科在交叉领域的不断深化和发展。以纳米科技为依托的药剂递送系统,可有效减少农药使用量,提升农药利用率,具有广阔的应用前景。该文结合最新的纳米农药研究进展,重点论述纳米农药的概念,介绍纳米农药的载体种类,分析纳米农药扩大靶标接触面积、促进植物内吸作用、提升叶面附着能力和调控药剂精准释放的增效机理,并对纳米农药的前沿应用进行展望。
Unscientific application of pesticides has led to a series of ecological and environmental security issues,which constrains the sustainable agricultural development in China.The rapid progress in nanotechnology promotes the development of modern plant protection as an interdisciplinary field.Nano-based pesticide delivery system can reduce the application of pesticides and increase the utilization rates of pesticides,which has a good potential in future applications.Based on the recent advances in nanopesticides,this review introduced the concept and carriers of nanopesticides,analyzed the synergistic mechanisms of nanopesticides in increasing contact area with target pests,promoting plant uptake,increasing adhesive ability to leaves,and regulating the release of pesticides.The future prospects of nanopesticide application were also discussed.
