One-Pot Fabrication and Characterization of Silver Nanoparticles Using Solanum lycopersicum: An Eco-Friendly and Potent Control Tool against Rose Aphid, Macrosiphum rosae

Abstract

The espousal of nanotechnology is a current come-up of the present revolution. As we know that the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae), is a key pest on rose plant in Kashmir Valley, India, it exhibits a worldwide distribution. In the present study, we have synthesized biologically silver nanoparticles (Ag NPs) from Solanum lycopersicum and characterized them by UV-vis spectroscopy, TEM, and X-RD analysis. The experiment was performed by leaf dip method. Insecticidal solutions of different Ag NPs concentrations, namely, 200, 300, 400, and 500 ppm, were tested on M. rosae. For assessment purposes, leaves were treated with distilled water (used as control). Aphid mortality data revealed that the Ag NPs were effective at 500 ppm concentration. As the concentration and day’s treatment increased, the aphid mortality rate also increased. There were statistically significant differences in M. rosae mortality between concentrations by LSD at 5%. In wrapping up, the use of Ag NPs in pest control processes will be the most novel eco-friendly approach in the Kashmir Valley, India, in future.

Biosynthesis of Silver Nanoparticles by Marine Actinobacterium Nocardiopsis dassonvillei and Exploring Their Therapeutic Potentials

“…Bio-AgNPs synthesized by M1 strain have insecticidal activity against M. rosae found on R. damascene var semperflorens ( Table 4 ). Bio-AgNPs had the highest mortality rate after 48 h, with the exception of 200 μg/ml, which had the highest mortality rate after 36 h. AgNPs were effective as insecticides at a concentration of 500 ppm ( Bhattacharyya et al, 2016 ). The extraordinary strength, chemical reactivity, and electrical conductivity of nanoparticles may explain their remarkable efficacy as insecticides.…”

“…The insecticide activity of Bio-AgNPs was evaluated using the plant dip technique established by Bhattacharyya et al (2016) . An insect colony of Macrosiphum rosae was grown on potted rose plants at 22 ± 2°C at the Entomology Laboratory, Department of Zoology, Taif University, KSA.…”

Tiny Flies: A Mighty Pest That Threatens Agricultural Productivity—A Case for Next-Generation Control Strategies of Whiteflies

“…Nanotization of a chemical pesticide viz: deltamethrin has resulted in ~10-fold enhancement in the toxicity of the pesticide against the green-house whitefly ( T. vaporariorum ) [ 172 ]. Researchers have also explored metal-NPs in general and Ag- and Zn-NPs in particular as pesticides to achieve effective control of sap feeders [ 173 , 174 , 175 ]. For example, Bhattacharya et al, 2016, synthesized biologically active Ag-NPs from tomatoes and tested against the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae), a key pest on the rose plant.…”

“…For example, Bhattacharya et al, 2016, synthesized biologically active Ag-NPs from tomatoes and tested against the rose aphid, Macrosiphum rosae (Hemiptera: Aphididae), a key pest on the rose plant. When leaves were dipped in insecticidal solution of Ag-NPs at a concentration of 400 and 500 ppm, 100% mortality of adults was observed in four and three days, respectively [ 173 ]. Similarly, decreased population density of B. tabaci nymphs was recorded on leaves of eggplants treated with Ag-NPs (3000 ppm) prepared from jujube leaf aqueous extract under greenhouse conditions [ 174 ].…”

Biogenic silver nanoparticles from Trichodesma indicum aqueous leaf extract against Mythimna separata and evaluation of its larvicidal efficacy

“…Th e use of plant extracts also reduces the cost of microorganisms' isolation and culture media thereby enhancing the cost competitive feasibility over nanoparticle synthesis by microbes (Prasad 2014). Nanostructure materials show unusual physical, chemical and biological properties, which are completely distinct from their bulk materials and individual molecules Bhattacharyya et al 2016). Nanotechnology includes encapsulation and entrapment of nanoagrochemicals such as nanofertilizers, nanopesticides, nanoherbicides, plant growth stimulating nanoscale biomolecules and other active substances by using polymers, dendrimers, surface ionic attachments etc.…”
