“…Although crop rotation has been documented as a safe method for controlling soil-borne diseases like Fusarium solani (Liu et al, 2009), it is often ineffective due to varying climate conditions and economic bene ts (Liu et al, 2010). The traditional approach of seed dressing and eld application with classical chemical fungicides have been utilized to reduce and suppress some Fusarium diseases (Musheer et al,2022); However, the adverse impacts of this chemical fungicide on the environment and human health have pushed farmers to focus on creating harmless agricultural management practices. Therefore, there is an urgent need to identify a viable and harmless strategy for preventing the spread and development of Fusarium root rot.…”

Incorporating green chemistry concepts into nanotechnology is an important focus area in nanoscience. The demand for green metal oxide nanoparticle production has grown in recent years. The beneficial effects of using nanoparticles in agriculture have already been established. Here, we highlight some potential antifungal properties of Zizyphus spina leaf extract-derived copper oxide nanoparticles (CuO-Zs-NPs), produced with a spherical shape and defined 13–30 nm particle size. Three different dosages of CuO-Zs-NPs were utilized and showed promising antifungal efficacy in vitro and in vivo against the selected strain of F. solani causes tomato root rot disease and is molecularly identified with accession number (OP824846). In vivo, results indicated that, for all CuO-Zs-NPs concentrations, a significant reduction in Fusarium root rot disease occurred between 72.0 to 88.6% compared to 80.5% disease severity in infected control. Although treatments with either the chemical fungicide (Kocide 2000) showed a better disease reduction and incidence with (18.33% and 6.67%) values, respectively, than CuO-Zs-NPs at conc. 50 mg/l, however CuO-Zs- NP at 250 mg/l conc. showed the highest disease reduction (9.17 ± 2.89%) and lowest disease incidence (4.17 ± 3.80%). On the other hand, CuO-Zs-NPs at varied values elevated the beneficial effects of tomato seedlings' vigor at the initial stages and plant growth development compared to either treatment with the commercial fungicide or Trichoderma Biocide. Additionally, CuO-Zs-NPs treatments introduced beneficial results for tomato seedlings' development, with a significant increase in chlorophyll pigments and enzymatic activity for CuO-Zs-NPs treatments. Also, it was indicated that treatment with CuO-Zs-NPs led to a rise in the number of mature pollen grains compared to the immature ones. Even though the data showed that CuO-Zs-NPs have a unique anti-fungal mechanism against F. solani, they nevertheless imply that CuO-Zs-NPs might be a useful environmentally friendly controlling agent for the Fusarium root rot disease that affects tomato plants.
