Increasing concerns about chemical fungicides require sustainable alternatives for crop protection. Microbe-mediated synthesis of metal nanoparticles offers a sustainable, eco-friendly and highly effective strategy plant disease management. This study investigates the mycosynthesis zinc oxide (ZnO NPs) using culture filtrate Trichoderma harzianum their antifungal activity against Alternaria brassicae . Nanoparticles were synthesized under optimized conditions cell-free (CFCF) concentration, substrate pH temperature. Ultraviolet-visible (UV-Vis) spectroscopy confirmed an absorption peak between 200 400 nm, while X-ray diffraction (XRD) confirms hexagonal crystal structure with average size 29 nm. Dynamic light scattering (DLS) zeta potential analysis revealed hydrodynamic 50.79 nm surface charge −17.49 mV, indicating good stability. Fourier transform infrared (FTIR) identified functional groups (C=O, N-O, O-H) that are crucial stabilization. Scanning electron microscopy (SEM) High-resolution transmission (HR-TEM) spherical, rod-shaped sizes 12 41 Mycogenic-zinc (M-ZnO significantly inhibited mycelial growth A. by 91.48% at μg/mL, compared to chemically ZnO NPs μg/mL (79.62%) mancozeb 0.2% (82.96%). SEM-EDX deformations M-ZnO in fungal hyphae, confocal laser scanning (CLSM) showed increased reactive oxygen species (ROS) formation impaired membrane integrity treated cells. Stress enzyme superoxide dismutase (SOD) catalase (CAT) 44.2 U/mol 39.6 NPs. Our studies suggest T. have even lower doses can be used as alternative traditional without affecting environment.

Plant responses to abiotic stresses through diverse mechanisms and strategic measures in utilizing nanomaterials have positively impacted crop productivity. Stress can cause membrane depletion, reactive oxygen species formation, cell toxicity death, reduction plant growth. However, mitigate some of the negative impacts enhance yield. Some endophytic microbes synthesize nanomaterials, which maintain health growth via nitrogen fixation, siderophore production, phytohormones synthesis, enzyme production without any pathological effects. Nanoparticle-synthesizing endophytes also help boost biochemical physiological functions by ameliorating impact stresses. The increase use implementation nano-growth enhancers from beneficial microbes, such as nano-biofertilizers, nano-pesticides, nano-herbicides, nano-fungicides are considered safe eco-friendly ensuring sustainable agriculture agrochemical usage. Promisingly, nanotechnology concepts aim sustain protect plants oxidative activation anti-oxidative enzymes. relieve stress still require further discussion literature. Therefore, this review is focused on induction tolerance plants,
