Potato (Solanum tuberosum) is the third crucial global crop facing threats from Alternaria solani, a necrotrophic fungal pathogen causing early blight disease. Beyond crop impact, it leads to substantial production reduction and economic losses worldwide. This study introduces a green synthesis method for producing Ferric Oxide nanoparticles (FNPs) using dried Guava (Psidium guajava) leaves. Guava leaf extract acts as a reducing agent, with iron (III) chloride hexahydrate (FeCl3·6H2O) as the oxidizing agent. This study employed various characterization techniques for Ferric Oxide nanoparticles (FNPs). Fourier Transform Infrared Spectroscopy (FTIR) revealed peaks at 877 cm−1, 1180 cm−1, 1630 cm−1, 1833 cm−1, 2344 cm−1, and 3614 cm−1, associated with Maghemite vibrations, polyphenol compounds, and amino acids. UV–Vis spectroscopy exhibited a characteristic absorbance peak at 252 nm for FNPs. Scanning Electron Microscope (SEM) images illustrated particle sizes of 29-41 nm, and Energy Dispersive Spectroscopy (EDS) indicated elemental composition. X-ray diffraction (XRD) confirmed crystalline FNPs with peaks at 26.78, 30.64, 36.06, 38.21, 43.64, 53.52, 57.42, 63.14 and 78.32. Disease resistance assays demonstrated FNPs’ effectiveness against A. solani, reducing disease incidence and severity. In the leaf detach assay, concentrations of 15, 10 and 5 mg/L showed a dose-dependent reduction in disease severity and incidence. The Greenhouse Assay confirmed FNPs’ concentration-dependent effect on disease incidence and severity. The study also explored FNPs’ potential as biocontrol agents showing no adverse effects on overall plant development. Additionally, the study highlighted the agronomic potential of FNPs in enhancing plant growth and development emphasizing their role as micronutrients in biofortification. The findings suggest the promising application of FNPs in plant protection and biofortification strategies.

Iron (Fe) is necessary for plant growth and development. Iron deficiency disrupts major metabolic and cellular activities such as respiration, DNA synthesis, and chlorophyll synthesis. Iron also activates various metabolic pathways and is vital to numerous enzymes. Iron is widely distributed in soil, but plants do not readily absorb it. In addition to neutral pH, Fe also forms insoluble Fe complexes under alkaline conditions. The fundamental cause of Fe chlorosis is an imbalance between the solubility of Fe in soil and the demand for Fe by plants. Various Fe fertilizers, including organic, chelated, and inorganic, are administered to the soil and leaves to treat Fe deficiency and chlorosis. Currently, used Fe fertilizers are expensive, easily adsorb on soil particles, and cause Fe to leach out of the soil with water, thereby diminishing their efficiency. They also need to be applied repeatedly, resulting in an excessive Fe fertilizer concentration in the soil that can cause harm to the plants. The usage of Fe nanofertilizers in agricultural production has expanded to address the disadvantages of existing Fe fertilizers. The advantages of nanosized Fe fertilizers include their physical and chemical characteristics, such as the high surface area to volume ratio that aids in easy absorption by plants’ roots and leaves. Controlled‐release iron oxide nanofertilizers supply the regulated release of nutrients in a way that is coordinated with the nutritional needs of the crops. This improves the accumulation of nutrients in the plant, filling in the gap of nutrient deficiency and lowering environmental risks due to leaching. The possibility of iron oxide nanoparticles as Fe micronutrient fertilizers, their uptake and mechanism of action, advantages, and limitations are critically highlighted in this review article.
