Research Progress on Application of Nanotechnology in Preparation of Herbicides

At present, the application of nanotechnology has been involved in various fields of agriculture, and a series of progress has been made in the preparation of herbicide. The application of nanotechnology and nanomaterials can improve the performance of herbicides, thus achieving energy conservation and emission reduction and environmental protection. In this paper, the definition of nanotechnology, the classification of nanopesticides, the safety of nanopesticides and the application of nanotechnology in pesticides were briefly introduced. The application advantages of nanotechnology in herbicide preparation were further clarified. The research progress of nanoherbicide was reviewed from the aspects of mechanism, dosage form, preparation method and application status. Finally, the broad prospect, existing problems and development direction of nanotechnology in herbicide preparation were put forward.
