The ever‐increasing resistance of plant microbes towards fungicides and bactericides has been causing serious threat to production in recent years. For the development an effective antifungal agent, we introduce a novel hydrothermal protocol for synthesis chitosan iron oxide nanoparticles (CH‐Fe 2 O 3 NPs) using acetate buffer low pH 5.0 intermolecular interaction Fe NPs CH. composite structure elemental elucidation were carried out by X‐ray power diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive (EDX), Transmission (TEM), Fourier Transformed Infrared Spectroscopy (FTIR) Ultraviolet Visible Absorption (UV–vis spectroscopy). Additionally, activity was evaluated both In vitro vivo against Rhizopus oryzae which is fruit rot disease strawberry. We compared different concentrations (0.25%, 0.50%, 075% 1%) CH‐Fe 50% synthetic fungicide (Matalyxal Mancozab) figure suitable concentration application field. XRD analysis showed high crystalline nature with average size 52 nanometer (nm). SEM images revealed spherical shape range 50–70 nm, whereas, TEM also shape, ranging from 0 nm 80 nm. EDX FTIR results presence CH on surface NPs. band gap measurement peak 317–318 bare respectively. Antifungal significantly increased increase concentration. overall synergetic potential organometallic suggest use other Phyto‐pathological diseases due biodegradable nature.
