Abstract
Abstract Image
Low crop productivity due to pests and diseases can be resolved by safer, sustainable, and environmentally friendly pesticide nanoformulations.
In integrated pest management, the nanoencapsulation of botanical compounds is an important technique for enhancing the efficiency and stability of these substances. In this study, naringin-loaded neem oil nanoemulsion (NAR-NO NE) was synthesized and characterized for ζ-potential, particle size, stability, encapsulation efficiency, and drug release studies. In vitro release of naringin in double-distilled water revealed a sustained release profile up to a maximum of 59.3% from the NAR-NO NE within 24 h compared to naringin suspension, which showed a burst release of up to 82.3% within 24 h. Further, an optimized batch of NAR-NO nanoformulation was also characterized by transmission electron microscopy (TEM) and Fourier transform infrared (FTIR) spectroscopy. The optimized formulation showed a spherical morphology and was stable for up to 60 days of storage conditions. The comparative antibacterial potential of NAR-NO nanoemulsion and blank NO nanoemulsion was examined. NAR-NO nanoemulsion showed high antibacterial potential at the equivalent dosage level as against blank neem oil nanoemulsion. Finally, the biological evaluation of naringin-encapsulated neem oil nanoemulsion was studied against the bacterial blight of cluster beans.
