Pesticide is an important agricultural necessity to control plant diseases and pests, ensuring safe production of food. However, the low efficacy, large dosage and high-frequency use of conventional pesticide formulation seriously induced food safety and ecological environment issues. In this research, lambda-cyhalothrin solid nanodispersion (LCSND) was developed by a self-dispersing method.
The mean particle size of the lambda-cyhalothrin solid nanodispersion was 32.7 ± 1.1 nm. It exhibited excellent dispersibility, wettability and stability, especially the improved bioavailability compared to the commercial formulations. Notably, the solid nanodisperison had a small particle size and large specific surface area. The solid nanodispersion without organic solvents can minimize the environment pollution and overcome the instability characteristic of the liquid formulations.
Therefore, lambda-cyhalothrin solid nanodispersion has broad application prospects in agricultural production and environmental protection. © 2018 Society of Chemical Industry.
农药是防治植物病虫害、确保食品安全的重要农业必需品。然而，常规农药制剂的低功效、大剂量和高频使用严重引发了食品安全和生态环境问题。本研究采用自分散法制备了高效氯氟氰菊酯固体纳米分散体。
高效氯氟氰菊酯固体纳米分散体的平均粒径为 32.7±1.1nm。它表现出优异的分散性、润湿性和稳定性，尤其是与商业制剂相比，生物利用度得到了提高。值得注意的是，固体纳米分散体具有较小的粒径和较大的比表面积。无有机溶剂的固体纳米分散体可以最大限度地减少环境污染，并克服液体制剂的不稳定性。
因此，高效氯氟氰菊酯固体纳米分散体在农业生产和环境保护方面具有广阔的应用前景。© 2018 英国化学学会。
