Nanopesticide dosage forms are relatively single, and industry development has a long way to go

Nanopesticide is a pesticide preparation that uses functional materials and nanotechnology to stabilize the effective ingredients of pesticides in the formulation and use dispersion system in a nanoscale dispersed state, and can exert application properties that are different from those of the original dosage form when used. Nanopesticides are new pesticides. Compared with traditional pesticides, nanopesticides have the advantages of high efficiency, environmental protection, long duration of effect, and high stability. They are currently a hot spot in the field of pesticides.

my country is a major agricultural country in the world, with pesticide production scale and usage among the highest in the world. However, due to long-term large-scale and inefficient use of pesticides, pesticide residues in grains, fruits, vegetables, soil, and water bodies in many areas of my country exceed standards. The development of nanopesticides can not only achieve high efficiency and high value-added development of pesticides, but also help improve the quality and efficiency of agriculture.

The development of the nanopesticide industry is supported by policies. In January 2022, the “14th Five-Year Plan” National Pesticide Industry Development Plan issued by the Ministry of Agriculture and Rural Affairs and relevant departments mentioned that the innovative application of nanotechnology in pesticide formulations is encouraged; vigorous development of water Base-based, nano-based, ultra-low-capacity, sustained-release and other preparations. Under the guidance of policies, the research and development process of nanopesticides has accelerated, and the development of the industry will continue to improve.

According to the “2022-2027 China Nanopesticide Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, at present my country’s nanopesticide industrialization level is at the world’s leading level. Domestic companies and institutions engaged in nanopesticide R&D and production include the Chinese Academy of Agricultural Sciences, Nanjing Shansi Company, Mindelida, Zhongnong Lihua Biotechnology, etc.

In terms of dosage forms, nanopesticide dosage forms include microemulsions, nanoemulsions, nanodispersions, nanospheres, nanocapsules, nanomicelles, nanogels, etc. Due to technical limitations, there are currently few nanopesticide formulations and dosage forms that have been launched. The types are relatively single, mainly microemulsions, and there are fewer other types of pesticides. The future development of the nanopesticide industry has a long way to go.

Nanopesticide processing methods are mainly divided into two types, one is to directly process pesticide active substances into nanoscale particles; the other is to use nanomaterials such as polymers, solid liposomes, and silica as carriers through adsorption, coupling, and encapsulation. , mosaic and other methods to load pesticides to construct a nano drug loading system. Nanopesticides are a new trend in pesticide development, and the industry has broad prospects for future development. However, at present, nanopesticide research is still in its early stages, and industry development still suffers from low stability of preparation technology, imperfect and unified detection technology/evaluation system, and lack of systematic mechanisms. research and other issues.

Industry analysts said that nanopesticides are innovative applications of nanomaterials and technology in the field of pesticides. The development of nanopesticides can not only realize the Green and efficient development will also help to improve the quality and efficiency of pesticides. The nanopesticide market has broad development prospects, but the market is still in its early stages of development and pesticide formulations are relatively single. In the future, the nanopesticide industry still needs further exploration in terms of preparation technology, product formulations, standard formulation, and mechanism research.
