“…4B). The SEM images in the present results, obtained for the mycosynthesized ZONPs were similarly as irregular in shape and matched to the previous findings (Manimegalai et al 2023). The occurrence of zinc oxide element, which denotes the reduction of a zinc ion in the reaction mixture, was detected via EDX investigation.…”

Potato (Solanum tuberosum) crops have experienced a 22% reduction due to attacks from microbial pathogens and pests. Dry rot disease occurred from risks in El-Minya governorate, Egypt, where potato is the major cultivated crop. Potato cultivar ‘Cara’ samples were collected from the markets of six regions in El-Minya for isolation. They were also tested for the application of biosynthesized zinc oxide nanoparticles (ZnONPs) for disease management. The ability of Exserohilum rostratum to synthesize ZnONPs was documented via UV-visible, X-ray diffraction, Fourier transform infrared spectrum, and transmission and scanning electron microscopy. Spherical shape and crystallite small size (51.0 ± 3.0 nm) were attributed to the created ZnONPs. The ZnONPs were applied in the bio-control of the causative agent (Fusarium nygamai) of dry rot disease and large economic loss of potato cv. ‘Cara’ productivity. The mycosynthesized ZnONPs by E. rostratum at 100 μg/ mL (3 mM) showed antifungal activity against F. nygamai with higher reducing value of mycelium growth diameter 2.0 ± 0.14 cm compared to Revanol 50%, traditional product with a diameter of 3.85 ± 0.10 cm. Overall, ZnONPs are an excellent agent that can be applied to repress the most common fungal disease of potato.

“…The presence of secondary metabolites in S. cordifolia leaf extract reduces Zn 2+ ions to zero valent Zn atoms, which initiate the nucleation process and play a crucial role in the conversion of residual Zn 2+ into ZnO. Additionally, the zinc oxide acts as a reluctant as well as a stabilizing and capping agent for synthesizing the bio‐fabricated ZnONPs [44,45] . FTIR analysis revealed the presence of functional groups, such as alkyl halides, aromatic, nitro compounds, amides, anhydrides, carboxylic acids, aldehydes, and alkenes, in S. cordifolia .…”

[44,45] FTIR analysis revealed the presence of functional groups, such as alkyl halides, aromatic, nitro compounds, amides, anhydrides, carboxylic acids, aldehydes, and alkenes, in S. cordifolia. Similar results were found with ZnO NPs from other extracts, including Cocus nusifera extract, Solanum lycopersicum and Cumin cyminum [46] and [47] found that the peak value of 3645.77 cm À 1 for ZnONPs obtained from Allergi mairarum extract matched with the OÀ H graph, whereas the range of the peak value of 1697.96 cm À 1 was linked to C=O stretching.…”

Strobilanthes cordifolia has emerged as a promising material in traditional medicine. In this study, we have made an attempt to synthesize zinc oxide nanoparticles derived from S. cordifolia leaf. The team employed a wide range of techniques including UV, FT‐IR, XRD, FE‐SEM with EDAX, HR‐TEM with SAED, DLS, Zeta potential, BET and PZC analysis to thoroughly examine the properties of the NPs. FTIR analysis provided evidence of various functional groups within the NPs. XRD analysis demonstrated the crystal nature and phase purity of the NPs. SEM analysis showcased the spherical shape of the particles, while TEM revealed their rod‐like shape with sizes averaging at approximately 10 nm. DLS analysis indicated the average particle size, and the high zeta potential value confirmed the stability and BET analysis deciphered the specific surface area of the biosynthesized NPs. The NPs confirmed strong antioxidant properties with DPPH, ABTS, and hydroxyl radicals. Enzyme studies confirmed good anti‐cholinergic activity and anti‐inflammatory efficacy, highlighting their potential therapeutic benefits. The NPs demonstrated promising wound healing properties. Overall, this research study sheds light on the medicinal aspects of zinc oxide nanoparticles from S. cordifolia leaf extract and it offers exciting prospects for future exploration and development in this field.
