“…The most attractive and cost-effective nanomaterials for environmental protection and water remediation processes are derived from noble metals. In this application, the high surface area to volume ratio, chemical stability, and enhanced catalytic activity properties from plant extract-mediated green synthesized AuNPs and AgNPs can be employed for water monitoring, purification, drinking water treatment, and agriculture wastewater treatment [ 147 , 148 ].…”

Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and agricultural applications. Nanobiotechnology, combined with green chemistry, has great potential for the development of novel and necessary products that benefit human health, environment, and industries. Green chemistry has an important role due to its contribution to unconventional synthesis methods of gold and silver nanoparticles from plant extracts, which have exhibited antimicrobial potential, among other outstanding properties. Biodiversity-rich countries need to collect and convert knowledge from biological resources into processes, compounds, methods, and tools, which need to be achieved along with sustainable use and exploitation of biological diversity. Therefore, this paper describes the relevant reported green synthesis of gold and silver nanoparticles from plant extracts and their capacity as antimicrobial agents within the agricultural field for fighting against bacterial and fungal pathogens that can cause plant, waterborne, and foodborne diseases. Moreover, this work makes a brief review of nanoparticles’ contribution to water treatment and the development of “environmentally-friendly” nanofertilizers, nanopesticides, and nanoherbicides, as well as presenting the harmful effects of nanoparticles accumulation in plants and soils.

“…As an alternative to the above, "green synthesis" has been used and has shown to be environment friendly, since it involves the use of yeasts, plant extracts, or microorganisms (bacteria and fungi) in the production of nanoparticles that have antibacterial/antifungal properties (Sastry et al, 2003). These nanoparticles can be used to mitigate the pathogenic load of numerous compounds and surfaces (Graily-Moradi et al, 2020).…”

New natural reducing agents with a lower negative impact on the environment and with a high antimicrobial potential are required for the process of obtaining silver nanoparticles through the chemical reduction method. The use of plant extracts can be a fast track in the formation of nanoparticles. In this case, organic compounds such as terpenes, flavonoids, enzymes, proteins, and cofactors present in plants act as reducing agents for nanomaterials. This research evaluated the antimicrobial property of silver nanoparticles from extracts of Crescentia cujete L. The presence of quercetin (flavonoid) was determined by high-performance liquid chromatography (HPLC); the production of silver nanoparticles (AgNPs) was established by green synthesis; the size and morphology of the nanomaterials were evaluated by scanning electron microscope (SEM). The antimicrobial capacity was studied by two analysis methods: modified culture medium and surface seeding. The presence of quercetin (26.55 mg L-1) in the crude extract of Crescentia cujete L., identified by HPLC, was evidenced. Nanoparticle formation was spherical, with an average size of 250 ± 3 and 460 ± 6 nm. Microbiological cultures with treatment showed 94% microbial inhibition. It was concluded that the Crescentia cujete L., leaves shoed an acceptable concentration of quercetin to be used as a useful adjuvant to enhance the reduction of NPs synthesis. The nanoparticles produced by green synthesis proved to have a positive effect to combat pathogenic microorganisms.

“…Metals play an important role in the plant management; application of direct metal can cause phytotoxic effects to plants but once it was used with nanotechnology improves plant's quality and quantity [12]. Nano agriculture lies on various types of metals like silver [13], silica [14], sulphur [15], gold [16], titanium [17] etc. but silver particles has been widely used since very long time because of its antimicrobial and anti-viral properties [18-23] also silver nanoparticles are hydrophilic in nature so disperse easily and distribute uniformly in water [24,25].…”

In the current situation several types of synthetic pesticides are available but they are harmful for the ecosystem and do possess a devastating impact on human health. The other side organic fungicides and biocontrol agents are also accessible in the market which relies on specific environmental conditions and can be used only under particular situations. Most of the organic methods are slow and time-consuming processes and contrary farmers don't have time as biological processes of the plants are fast, so the timing is foremost valuable for economic yields. To combat the existing situation there is an alternate solution exists in the form of nano technology for the management of plant pathogens and currently nano fungicides i.e., AgNps, CuNPs, TiO 2 , chitosan nanoparticles and nano emulsions are being used in the sector of plant diseases management. These days' nanoparticles are used in the agriculture sector because of their antifungal, antibacterial and antiviral properties. Nano silvers (silver nanoparticles) and nano sensors are applied against abiotic stresses and insect pests as fertilizers, growth promoters and insecticides respectively. Presently many researches were conducted on silver particles and silver nano-based fungicides show high effectivity against plant pathogens. Hopefully in the future, silver nanoparticles will be marketed for the control of plant diseases and insect pests and for the detection of pesticides. Therefore, this manuscript addresses all the possible applications and approaches of nanoparticles as effective and ecofriendly tools imparting growth to the plants which reduces impact of plant diseases on plant part as plant system is strengthen and to combat against plant pathogens & insect pests because of their antifungal, antibacterial, antiviral & insecticidal properties.
