Recently, a kind of nano-bio-pesticides that were prepared through nano-chemical treatment of nicotine and had no toxic or side effects on humans and animals appeared on the site of research and development of Sichuan nano-bio-pesticides. The pesticidal effect of this pesticide is 3 times that of ordinary pesticides, and the production cost is only half that of ordinary pesticides. According to Jiang Weimin, head of Sichuan High-tech Office, Sichuan Science and Technology Department issued a scientific research project on the "development and development of nano-bio-pesticides" in 2003. The Sichuan Academy of Agricultural Sciences and Guanghan Hengyu New Materials Co., Ltd. cooperated to carry out technical research. Recently, it has successfully developed an environmentally friendly, highly effective, and low-toxic plant-derived nano biological pesticide. Using a 58,000-fold transmission electron microscope, 95% of the pesticides were found to be less than or equal to 100 nanometers in size. Because of the nanoization of the original plant-derived pesticide particles, the coarse and partially solid phases represented by the complex components of the original Chinese medicines have been realized. Sedimentary, part of the volatile oil floating, a considerable part of the water-insoluble complex heterogeneous system, has become a highly dispersed and easily soluble in water stable homogenous state, its physical, chemical and biological properties are also mutated. Nanotechnology is used to promote plant cell wall breaking, effective lipid-soluble and water-soluble insecticidal substances are effectively released and directly acted on pests, greatly improving the efficacy.
