Antibacterial and Antifungal Studies of Biosynthesized Silver Nanoparticles against Plant Parasitic Nematode Meloidogyne incognita, Plant Pathogens Ralstonia solanacearum and Fusarium oxysporum

Abstract

The possibility of using silver nanoparticles (AgNPs) to enhance the plants growth, crop production, and control of plant diseases is currently being researched. One of the most effective approaches for the production of AgNPs is green synthesis. Herein, we report a green and phytogenic synthesis of AgNPs by using aqueous extract of strawberry waste (solid waste after fruit juice extraction) as a novel bioresource, which is a non-hazardous and inexpensive that can act as a reducing, capping, and stabilizing agent. Successful biosynthesis of AgNPs was monitored by UV-visible spectroscopy showing a surface plasmon resonance (SPR) peak at ~415 nm. The X-ray diffraction studies confirm the face-centered cubic crystalline AgNPs. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques confirm the rectangular shape with an average size of ~55 nm. The antibacterial and antifungal efficacy and inhibitory impact of the biosynthesized AgNPs were tested against nematode, Meloidogyne incognita, plant pathogenic bacterium, Ralstonia solanacearum and fungus, Fusarium oxysporum. These results confirm that biosynthesized AgNPs can significantly control these plant pathogens.

Silver Nanoparticles (AgNPs) in Urea Solution in Laboratory Tests and Field Experiments with Crops and Vegetables

“…The disinfectant action of AgNPs, which is known and applied on a larger s medicine [49,50], has been investigated in recent decades for possible application i tecting agricultural and horticultural plants [51,52]. The AgNPs used in our resear nificantly reduced the infestation of germinating seeds by pathogens.…”

Green Synthesis of Silver Nanoparticles Using the Plant Extract of Acer oblongifolium and Study of Its Antibacterial and Antiproliferative Activity via Mathematical Approaches

“…In a similar study, the green synthesis of silver nanoparticles was orchestrated with the aim of increasing crop production, growth, and resistance to disease. The synthesized nanoparticles were analyzed for their antifungal and antibacterial properties against several plant pathogens and strengthened the foundation for the synthesis of silver nanoparticles [20]. Following this, the current study reports an unprecedented, one-step, costeffective method for AgNPs biosynthesis at room temperature from Acer oblongifolium plant leave extract.…”

Effect of Phyto‐Assisted Synthesis of Magnesium Oxide Nanoparticles (MgO‐NPs) on Bacteria and the Root‐Knot Nematode

“…In comparison to the control, minimum inhibitory concentration (MIC) is defined as the concentration at which no growth is seen. The noninhibitory concentration (NIC) is the lowest concentration at which normal observable growth can occur [ 4 , 7 ].…”

“…As described in the literature [ 5 , 6 ], a number of variables, such as airflow, breathing rate, lung volume, and particle size, affect the delivery of NPs to the lung as well as their distribution and deposition. Plant-based synthesis of nanoparticles is a simple, environmentally safe, economical, and safer approach for human use [ 7 ]. Plants or plant extracts are utilized as reducing and capping agents in the manufacture of nanomaterials [ 8 , 9 ].…”
