“…The results of the present study showed that AgNPs have antibacterial and antifungal activity in vitro against R. solanacearum and F. oxysporum, respectively. This finding is consistent with previous studies, which showed that AgNPs are effective for killing phytopathogens (including fungi, Gram-positive bacteria, and Gram-negative bacteria) ( Table 1 ) [ 23 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Not all of them have carried out a basic characterization of the biogenic AgNPs obtained, which makes it difficult to explain the mechanism by which AgNPs interact with these microorganisms.…”

“…Until now, only a few articles including (at the same publication) results of antinematode, antifungal, and antibacterial studies against plant pathogens using AgNPs have been reported [ 23 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. Therefore, in this work, we screened the biosynthesized AgNPs against the plant pathogenic bacterium, R. solanacearum, and fungus, F. oxysporum .…”

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.

“…UV-Vis spectrophotometer was used to first confirm synthesis and presence of nanoparticles in the reaction mixture. Earlier literature showed that absorption between 400 -450 nm is usually characteristic of silver NPs in the UV-Vis region (Sathishkumar et al 2009;Ashraf et al 2020). Clear peaks recorded at 413 and 410 nm in case of reaction mixture containing extracts of white mulberry and bael leaves thus followed the trend.…”

Antifungal metal structures, using silver at nanoscale, were synthesized using leaves extract of two indigenous trees i.e., Morus alba (white mulberry) and Aegle marmelos (bael fruit). The antifungal characteristics of synthesized silver nanoparticles (AgNPs) was verified against Fusarium oxysporum, the causal agent of Fusarium wilt and Macrophomina phaseolina, the pathogen of charcoal rot, taking tomato as a model plant. Synthesized nanoparticles were checked against selected fungi in concentrations of 25, 50, 75 and 100 μg/mL. Negative control received no nanoparticles but sterilized water, whereas positive control plants were treated with chemical fungicide (Nativo). Result of in vitro and greenhouse experiments confirmed the potential of synthesized nanoparticles to reduce fungal growth and disease incidence. However, the NPs synthesized using leaves extract of white mulberry were more effective. In green house trials, the plants treated with NPs in a concentration of 100 μg/mL showed parallel results as were recorded in plants receiving fungicide. Similarly, both selected fungi also depicted slight variation in their responses towards various treatments as percentage of growth inhibition as well as disease incidence was more in F. oxysporum than in M. phaseolina. UV-spectrophotometer ascertained the optimization conditions by adjusting concentrations of silver nitrate between 1, 1.5, 2, 2.5 and 3 mM, incubation period of 24, 48, 72 and 96 h and pH of biosynthesis system adjusted at 4, 6, 8, 10 and 12. FTIR confirmed the presence of different functional groups available both in plant extracts and nanoparticles while, SEM indicated spherical, polydisperse morphology of AgNPs with size ranges from 20–48 nm respectively. In pot experiment nanoparticles synthesized using white mulberry leaves reduced fusarium infection up to 97% and macrophomina rot up to 92%. Nanoparticles synthesized using bael leaves extract were comparatively less effective against selected fungi than those synthesized using white mulberry leaves extract. Hence these results provided basis for the use of green synthesized NPs using white mulberry leaves extract as an alternative to conventional fungicides to help reduce environmental pollution. © 2021 Friends Science Publishers
