Interpretive Summary:

Technical Abstract: The high demand for protein consumption in the ever-increasing population has put great pressure on food animal and crop production systems. To increase profit margin along with productivity, the utilization of antibiotics to promote animal growth and reduce mortality has contributed to the emergence of resistant bacteria that may affect humans as well as the animals themselves. Thus it is necessary to find a simple and economical way to counter or reduce the proliferation of these antibiotic resistant bacteria. Nanoparticles with antimicrobial properties hold a great promise in this arena. This study utilized silver nanoparticles synthesized from bitter melon (Momordica charantia) and sugar cane (Saccharum officinarum) extracts to test against common agricultural pathogens (e.g., fungi and Escherichia coli). The synthesized nanoparticles were characterized and confirmed as silver nanoparticles by using the UV spectroscopy, FTIR, and SEM analysis. The results show that these silver nanoparticles are effective against agricultural fungi and pathogens such as Phytophthora capsici, Colletotrichum acutatum, Cladosporium fulvum, and Escherichia coli.
