Implication

In vitro experiment demonstrates potent antifungal activity of pure citral against Fusarium oxysporum, indicating biofungicide potential despite lower efficacy from nanoencapsulation.

Key Points

To evaluate the antifungal efficacy of free and chitosan-nanoencapsulated citral against Fusarium oxysporum f.sp. lycopersici, a devastating soil-borne tomato pathogen.
Synthesized citral-loaded chitosan nanoparticles and characterized them using scanning electron microscopy (SEM), FT-IR, encapsulation efficiency (EE), loading capacity (LC), and in vitro release profiling.
Evaluated antifungal activity against Fusarium oxysporum f.sp. lycopersici through in vitro mycelial growth inhibition assays, minimum inhibitory concentration (MIC), and minimum fungicidal concentration (MFC).
Nanoparticles displayed spherical morphology (33–301 nm), encapsulation efficiency of 2.9%–7.2%, loading capacity of 0.6%–1.3%, and sustained in vitro release.
Pure citral achieved 100% mycelial growth inhibition at 500 µg/mL, with both MIC and MFC established at 512 µg/mL.
Citral nanoparticles reached a maximum mycelial inhibition of 27% at 1000 µg/mL and exhibited an MIC of 4096 µg/mL.
