BACKGROUND This work reports the isolation and screening of rhizospheric microflora of chickpea and their role in the biosynthesis of silver nanoparticles (AgNPs). The antifungal potential of AgNPs for control of wilt disease of chickpea, caused by Fusarium oxysporum f. sp. ciceri (FOC) was evaluated in vitro and in vivo pot experiments. The effect of AgNPs on seed germination and soil community was also evaluated. RESULTS Among microbial strains, two bacteria, Pseudomonas sp. and Achromobacter sp. and two fungi, Trichoderma sp. and Cephalosporium sp., were identified for biosynthesis of AgNPs. AgNPs were confirmed by UV‐visible spectra (λ = 420 nm) and transmission electron microscopy (TEM) with size 20–50 nm. AgNPs showed very high antifungal activity (95%) against FOC in vitro at 100 µgmL−1 concentration. Pot experiments showed maximum and minimum reduction in wilt incidence over control, i.e. 73.33% for AgNPs and copper‐oxychloride (CuOCl) i.e. 26.67%, respectively. Seeds coated with AgNPs showed high germinability up to 98% and no negative impact was observed on soil community. CONCLUSION This study demonstrated the role of AgNPs against the fungal disease of chickpea that can be extended to other diseases of chickpea and other important Indian crops. © 2018 Society of Chemical Industry

by dispersion, suspension emulsion, or miniemulsion polymerization, while the preparation of polymer nanocarriers made from preformed polymers usually occurs by coacervation methods such as salting out, [13] emulsification-diffusion, [14] nanoprecipitation, and supercritical fluid technology. [15,16] Among those different preparation techniques, miniemulsion is particularly attractive due to its ability to prepare nanocarriers from either mono mer or polymer while allowing for the efficient loading of large doses of therapeutic agents, which can be lipophilic and/or hydrophilic compounds. [17] Furthermore, miniemulsion provides the opportunity to finely tune particle size distribution while preparing emulsion with high solid content of polymers. [18][19][20] The crosslinking of polymer-containing nanodroplets formed by miniemulsion is a particularly attractive method to produce nanocarriers (Figure 1). Hollow nanocapsules can be prepared by a polyaddition or polycondensation reaction occurring at the droplets interface. [21] In order to prepare nanocarriers, the polymer is dissolved in a good solvent and emulsified with an immiscible nonsolvent forming the continuous phase. After the emulsification, a crosslinking agent, soluble in the continuous phase, is added to the emulsion and the poly addition or polycondensation reaction between the polymer and crosslinking agent occurs at the surface of the droplet. When the reaction kinetic is fast enough, a shell insoluble in both phases can be formed at the interface. [22] To control the size and size distribution of the nanocapsules prepared by the polyaddition/polycondensation reaction at the droplet interface, it is critical to control the preparation of the miniemulsion used as a precursor. The two main factors leading to the broadening of the size distribution of the nanodroplets during miniemulsion are (i) Ostwald ripening and (ii) coalescence of the droplets occurring through collision. The coalescence could be controlled by the addition of an appropriate surfactant, which provides electrostatic or steric stabilization thus preventing droplet coalescence. Ostwald ripening is affected by multiple factors such as droplet size, Laplace pressure, polydispersity, and solubility of the dispersed phase in the continuous phase. In general, Ostwald ripening could be limited by the addition of compounds increasing the osmotic pressure in the system. These chemicals need to be highly insoluble in the continuous phase but completely soluble in the Nanocapsules Polymer nanocarriers are used as transport modules in the design of the next generation of drug delivery technology. However, the applicability of nanocarrier-based technology depends strongly on our ability to precisely control and reproduce their synthesis on a large scale because their properties and performances are strongly dependent on their size and shape. Fundamental studies and practical applications of polymer nanocarriers are hampered by the difficulty of using the current methods to produce monodispersed ...

The applications and benefits of nanotechnology in the agricultural sector have attracted considerable attention, particularly in the invention of unique nanopesticides and nanofertilisers. The contemporary developments in nanotechnology are acknowledged and the most significant opportunities awaiting the agriculture sector from the recent scientific and technical literature are addressed. This review discusses the significance of recent trends in nanomaterial-based sensors available for the sustainable management of agricultural soil, as well as the role of nanotechnology in detection and protection against plant pathogens, and for food quality and safety. Novel nanosensors have been reported for primary applications in improving crop practices, food quality, and packaging methods, thus will change the agricultural sector for potentially better and healthier food products. Nanotechnology is well-known to play a significant role in the effective management of phytopathogens, nutrient utilisation, controlled release of pesticides, and fertilisers. Research and scientific gaps to be overcome and fundamental questions have been addressed to fuel active development and application of nanotechnology. Together, nanoscience, nanoengineering, and nanotechnology offer a plethora of opportunities, proving a viable alternative in the agriculture and food processing sector, by providing a novel and advanced solutions. © 2017 Society of Chemical Industry.
