Nanoscience will leave no field untouched by its ground breaking technical innovations; the agricultural sector is no exception. The advantage of using plants for the synthesis of nanoparticles is that they are easily available, safe to handle and possess a broad variability of metabolites that may aid in reduction. A number of plants are being currently investigated for their role in the synthesis of nanoparticles. Gold nanoparticles with a size range of 2- 20 nm have been synthesized using the live alfa alfa plants The antibacterial effects of Ag salts have been noticed since antiquity and Ag is currently used to control bacterial growth in a variety of applications, including dental work, catheters, and burn wounds. Different biological methods are gaining recognition for the production of silver nanoparticles (Ag-NPs) due to their multiple applications. The use of plants in the synthesis of nanoparticles emerges as a cost effective and eco-friendly approach. One of the most important applications of Ag –NPs is their use as an anti- bacterial agent. Melia azedarach L. was selected in this study for producing silver nanoparticles that are tested against E coli, Bacillus subtilis and Enterobacter aerogenes. It was found that Melia azedarach nanoparticles display strong potential for the synthesis of silver nanoparticles as antibacterial agents by rapid reduction of silver ions. The silver nanoparticles of Melia azedarach showed better antibacterial activity against E coli, Bacillus subtilis, Enterobacter aerogenes.
