“…Some studies showed that AgNPs synthesized from different fungal species can be employed in pest control [ 81 ]. In a study, Dhanasekaran and Thangaraj [ 82 ] evaluated the larvicidal activity of biogenically synthesized AgNPs against the larvae of Culex mosquito vector, which causes filariasis.…”

Nanotechnology is a new and developing branch that has revolutionized the world by its applications in various fields including medicine and agriculture. In nanotechnology, nanoparticles play an important role in diagnostics, drug delivery, and therapy. The synthesis of nanoparticles by fungi is a novel, cost-effective and eco-friendly approach. Among fungi, Fusarium spp. play an important role in the synthesis of nanoparticles and can be considered as a nanofactory for the fabrication of nanoparticles. The synthesis of silver nanoparticles (AgNPs) from Fusarium, its mechanism and applications are discussed in this review. The synthesis of nanoparticles from Fusarium is the biogenic and green approach. Fusaria are found to be a versatile biological system with the ability to synthesize nanoparticles extracellularly. Different species of Fusaria have the potential to synthesise nanoparticles. Among these, F. oxysporum has demonstrated a high potential for the synthesis of AgNPs. It is hypothesised that NADH-dependent nitrate reductase enzyme secreted by F. oxysporum is responsible for the reduction of aqueous silver ions into AgNPs. The toxicity of nanoparticles depends upon the shape, size, surface charge, and the concentration used. The nanoparticles synthesised by different species of Fusaria can be used in medicine and agriculture.Nanotechnology is a new and developing branch that has revolutionized the world by its applications in various fields including medicine and agriculture.

“…Besides, Campolo et al () reported that essential oil of citrus (EOs) as emulsions are included in polyethylene glycol (PEG) nanoparticles (EO‐NPs) improved higher mortality through contact on eggs and larvae in the pest tomato borer ( Tuta absoluta Meyrick). Besides, Sayed, Kim, and Behle () found that silver nanoparticles (AgNPs) synthesized by using the entomopathogenic bacterium, Bacillus thuringiensis kurstaki (Btk) improved virulent toward on cabbage looper larvae ( Thriclopusia ni Hübner). In regards to insect pest on grain during storage, Golden, Quinn, Shaaya, Kostyukovskya, and Poverenova () found that when the natural pest‐managing agent pulegone was encapsulated into nanoemulsions, improved high (>90%) mortality rates in rice weevil ( Sitophilus oryzae L) and red flour beetle ( Tribolium castaneum Herbst), for as long as 5 weeks.…”

Nanoscience and nanotechnology have been shown to have the capacity to help study, manipulation,design, and synthesis of new nano-sized materials to manufacture new products with desirable features never seen before. The unique properties of materials at nanoscale opens an excellent possibility for nanotechnology to be used in soil environmental remediation, and water, and air decontamination. In crop management, nanomaterials are used to regulate the controlled release of nutrients, fertilizers, and pesticides. However, it is not only necessary to expose the positive effects by the application of the nanomaterials but also to demonstrate the impacts on soil and nontarget organisms (plants, mesofauna, macrofauna, and soil microbiota). In this context, pieces of evidence on the adverse effects of engineered nanoparticles (ENP) on the physicochemical and biological properties of soils are discussed in this paper. We have found a diversity of contradictory results. The summaries, findings, and conclusions of most of the investigations support the need to understand the biological or physicochemical transformation and transport of ENP in soil, and in the plant-organism relationship. Better understanding regarding the soil biota coupled with the ecological ENP behavior could ensure the safe use of ENP. Nanomaterials can change the physicochemical and biological properties of the soils; consequently, long-term in situ field trials are required, and meanwhile, land-application of nanomaterials should be limited to scientific experiments to fill knowledge gaps to not jeopardize the global food production or the environment and worldwide human health.

“…Silver nanoparticles are also used in gene regulation, for instance a sublethal dose of silver nanoparticles was not found having direct effect on N 2 fixing (anfD, nifH, nifD, vnfD) and N 2 denitrifying (napB, norB, nirH, narG) genes but other involved genes (amoA1, amoC2) in nitrification is upregulated in Nitrosomonas europaea [49]. In tissue culture, the use of silver nanoparticles in callus formation, root and shoot generation have been reported, for instance Tecomella undulata explant medium with the use of silver nanoparticlefound increasingnumber of shoots and the formation of callus [50][51][52]. Silver nanoparticles also improve the quality of the plant when used astissue culture methods, for instance variety Solanum nigrum was improved by somaclonal variationwith the use of silver nanoparticles [53].…”

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.
