Preparation and Characterization of Emamectin Benzoate Solid Nanodispersion

الملخص EN

The solid nanodispersion of 15% emamectin benzoate was prepared by the method of solidifying nanoemulsion.

The mean particle size and polydispersity index of the solid nanodispersions were 96.6±1.7 nm and 0.352±0.041, respectively.

The high zeta potential value of 31.3±0.5 mV and stable crystalline state of the nanoparticles suggested the excellent physical and chemical stabilities.

The contact angle and retention compared with microemulsions and water dispersible granules on rice, cabbage, and cucumber leaves indicated its improved wettability and adhesion properties.

The bioassay compared with microemulsions and water dispersible granules against diamondback moths and green peach aphids provided an evidence of its enhanced biological activity.

This formulation composition could avoid organic solvents and obviously reduce surfactants.

It is perspective in raising bioavailability and reducing residual pollution of pesticides and further improving agricultural production and environmental safety.
