This study deals with the green synthesis of Co₃O₄ nanostructures using a simple reverse micelle-based method and evaluates their dual function as a plant growth promoter and bacterial disease control agent. Co₃O₄ nanotubes were synthesized using cobalt(II) chloride as a precursor, purified soybean oil as the organic phase and Tween 80 as a surfactant. The characterization of the nanostructures was carried out by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).</p> <p>The agricultural performance evaluation of these nanostructures in research showed that their application leads to significant improvement in growth parameters including shoot length, root length and dry weight of plants and reduction in the percentage of infected leaf area. The antibacterial mechanism was through cell membrane destruction and apoptosis induction. These results indicate that greenly synthesized Co₃O₄ nanotubes can be used as a dual-purpose agent in sustainable agricultural management to promote plant growth and control bacterial diseases.</p> Ramin Karimian Seyed Javad Davarpanah Copyright (c) 2026 Journal of Applied Plant Biology 2026-02-24 2026-02-24 4 1
