“…Silver nanoparticles, with their widespread range of antibacterial activities, have gained substantial attention as a prospective nano-pesticide used in agriculture. Numerous in vitro studies confirmed the activity of silver nanomaterials against the development of various pathogens [116]. The silver nanomaterial toxicity mechanism has not been entirely resolved yet; conversely, it can be noted that it is mainly developed from the silver ion discharge.…”

Nanotechnology implies the scientific research, development, and manufacture, along with processing, of materials and structures on a nano scale. Presently, the contamination of metalloids and metals in the soil has gained substantial attention. The consolidation of nanomaterials and plants in ecological management has received considerable research attention because certain nanomaterials could enhance plant seed germination and entire plant growth. Conversely, when the nanomaterial concentration is not properly controlled, toxicity will definitely develop. This paper discusses the role of nanomaterials as: (1) nano-pesticides (for improving the plant resistance against the biotic stress); and (2) nano-fertilizers (for promoting the plant growth by providing vital nutrients). This review analyzes the potential usages of nanomaterials in agroecosystem. In addition, the adverse effects of nanomaterials on soil organisms are discussed. We mostly examine the beneficial effects of nanomaterials such as nano-zerovalent iron, iron oxide, titanium dioxide, nano-hydroxyapatite, carbon nanotubes, and silver- and copper-based nanomaterials. Some nanomaterials can affect the growth, survival, and reproduction of soil organisms. A change from testing/using nanomaterials in plants for developing nanomaterials depending on agricultural requirements would be an important phase in the utilization of nanomaterials in sustainable agriculture. Conversely, the transport as well as ecological toxicity of nanomaterials should be seriously examined for guaranteeing its benign usage in agriculture.

“…In phytofabrication of nanoparticles, generally, the metal ions are added to the plant part extract and then continuously stirred in a magnetic stirrer. The formation of nanoparticles can be confirmed visually when the resultant solution changes its color [30,32]. It is due to the activity of the antioxidant, such as polyphenol, flavonoids, and phytoalexins, that act upon the metal ion and convert it to nontoxic element metal in nanoform.…”

Chitosan is a naturally occurring biopolymer having multifaceted applications in agriculture, medicine, food industry, and cosmetics. The association of this natural biopolymer with nanotechnology can produce revolutionary effects in plant protection and agriculture. Nano-chitosan can be fabricated using various methods. However, the green synthesis approach has gained attention in recent years. The green engineered nanoparticles are economical, energetically feasible, and environmentally benign. The biosynthesized nano-chitosan has evolved as a potential plant protection agent. Chitosan nanoparticles possess antifungal, antibacterial, and antiviral properties, and are found to be effective against seed-borne and soil-borne pathogens. Nano-chitosan also behaves as an effector molecule and induces local and systemic defense responses in plants. The mode of action of nano-chitosan involves alterations in membrane permeability, replication, cytoplasmic alterations, induction of defense-related genes, and cell lysis. Furthermore, chitosan nanoparticles can be used for soil improvement and can reduce pest and pathogen attacks, thereby promoting the growth of plants. The authors outline the methods of synthesis and characterization of chitosan nanoparticles, their utilization in plant protection and growth promotion, along with the underlying mechanisms.

“…The first strain of Pseudomonas stutzeri AG259 that was obtained from a silver mine, was the source of the discovery that bacteria could synthesize silver nanoparticles (Dutta and Kaman, 2017;Haefeli et al, 1984). At concentrations as low as 2.5 µg mL -1 , Nano-Ag exhibited inhibition of Citrobacter freundii, Erwinia cacticida and all the tested xanthomonads in vitro (Liang et al, 2017).…”

“…At concentrations as low as 2.5 µg mL -1 , Nano-Ag exhibited inhibition of Citrobacter freundii, Erwinia cacticida and all the tested xanthomonads in vitro (Liang et al, 2017). In the agricultural context, silver nanoparticles have proven effective in controlling plant pathogens at lower doses compared to chemicals, consequently reducing cultivation costs and promoting environmental sustainability (Dutta and Kaman, 2017).…”

The mesmerizing science of nanotechnology is the process of manipulating atoms and molecules to produce materials characterized by their minuscule dimensions, including nanoparticles ranging from 1 to 100 nanometers. Despite being relatively new areas of study, nanoscience and nanotechnology are rapidly emerging as the forefront of research, continually generating the latest discoveries. Every year, nearly 20-40% crop losses occur mainly due to diseases and pests. The only method currently used to control plant diseases are toxic pesticides and fungicides, which pose risks to both the human well-being and the ecosystem. To reduce these problems the only needed solution is nanotechnology. It employs the use of nanoparticles synthesized by various methods. Plant diseases are managed effectively by using diverse nanoparticles, like silver nanoparticles, copper nanoparticles and zinc oxide nanoparticles. The rapid detection of plant pathogens, the biosensor-based control of pests and diseases, soil management and other areas are all greatly impacted by nanotechnology.
