Background:
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.
Results:
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.
Conclusion:
Therefore, lambda-cyhalothrin solid nanodispersion has broad application prospects in agricultural production and environmental protection. © 2018 Society of Chemical Industry.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
