In recent years biogenic nanoparticles have emerged as an alternative approach for controlling agricultural pests. The current study investigates the nematicidal potential of green-synthesized silver oxide nanoparticles derived from <em>Vitex negundo</em> against second-stage juvenile (J2) and eggs of <em>M. incognita</em>.

The bioassay results revealed that both juveniles and eggs generally showed a concentration-dependent response. The <em>in vivo</em> treatment with biogenic nanoparticles showed reduced gall formation and increased plant growth in tomato plants. Maximum reduction in the galls and plant growth parameters was observed in higher concentrations (1000 ppm) of VND-AgONPs after 60 days compared to untreated inoculated control.

In this study, ZnO-NPs were utilized for establishment of callus and cell cultures in black seeds for the first time. Hypocotyl explants were cultured on Murashige and Skoog (MS) media with varying levels of ZnO-NPs, resulted in callus induction and biomass formation. Optimal response in callus growth parameters were observed when explants were grown on MS media supplemented with 60 mg/L ZnO-NPs, resulting in 71.2 % callus induction frequency, 28.2 g/L fresh biomass, 9.7 g/L dry biomass, and 63 % water content. A substantial increase in callus growth was observed when ZnO-NPs were combined with 6-Benzylaminopurine (BA) at ratio of 45:1.5 mg/L, resulting in 91.2 % callus induction frequency and 42.2 g/L fresh biomass. In cell suspension cultures, ZnO-NPs alone at 45 mg/L produced optimum callus biomass (60.9 g/L). However, in combination with BA, callus biomass did not increase significantly in cell cultures.

Green synthesis of metal nanoparticles represents an innovative and environmentally friendly approach in agriculture that enhances crop yield and quality. Unlike traditional physical and chemical methods, which are costly and produce harmful by-products, green synthesis uses biological agents like plants, fungi, and bacteria, making the process more sustainable and cost-effective. Bacterial cells demonstrate superior efficiency in the green synthesis of nanoparticles compared to plant cells. Their effectiveness is attributed to their unique morphological features, surface structures, and the presence of exopolysaccharides, sugars, proteins, enzymes, and various functional groups (such as carboxyl, phosphate, and amide). Interaction between bacterial cells and nanotechnology presents a promising approach for advancing smart agriculture by enhancing soil fertility, plant protection, and nanoparticle synthesis efficiency. By entering the structure of a living organism as an external factor, nanoparticles can cause extensive changes in the physiology and function of the cell. Therefore, the presence of a biological mediating agent with potential mechanisms capable of reducing the negative effects of nanoparticles can increase their efficacy as a long-term factor and reduce concerns about the harmful effects of nanoparticles on nature and living cells. By activating the pathways of NADPH, glutathione, and biofilm formation, this living agent first moderates the harmful effects of nanoparticles and acts as a filter, then provides them for the cell as a healthy biological-nanotechnological agent through a process known as green synthesis.

Four economically viable cassava root cultivars were evaluated for their tolerance to postharvest physiological deterioration (PPD) and quality retention after treatment with various chitosan-antioxidant formulations. The results indicated that the chitosan-quercetin formulation (CS-Q) was the most effective, achieving the lowest average H₂O₂ reduction of 67.7 % compared to untreated samples, followed by chitosan-beta-carotene (CS-BC) at 62.4 %, chitosan-ascorbic acid (CS-AA) at 38.3 %, and chitosan (CS) at 34.8 %. These reductions in H₂O₂ suggest that chitosan-antioxidant treatments can effectively delay PPD and extend cassava's shelf life for up to six months, depending on the cultivar, seasonal factors, and specific antioxidant composition. The successful implementation of this innovation offers a promising solution to delay PPD and enhance the efficiency of the cassava supply chain.

For this, healthy seeds of wheat were nanoprimed with Ag-CNPs and further inoculated with <em>A. flavus</em> so as to induce pathogenic stress. These seeds were sown in pots in a completely randomized block design and plants were raised from both nanoprimed and inoculated seeds, while plants were also raised from non-nanoprimed primed and uninoculated that served as control.
