Overview

Randomized trial evaluates antifungal effects of Cymbopogon martinii essential oil against fungal pathogens, implying a potential eco-friendly solution for papaya postharvest management.

Key Points

  • The study aims to assess the antifungal effects of Cymbopogon martinii essential oil against postharvest fungal pathogens affecting papaya.
  • Gas chromatography–mass spectrometry (GC–MS) analysis identified essential oil compounds.
  • Concentration-dependent antifungal activity was tested against Colletotrichum gloeosporioides and Fusarium longifundum.
  • Mechanistic investigations involved examining fungal membrane integrity and cellular leakage.
  • CMEO inhibited mycelial growth of C. gloeosporioides at 1500 µg/mL and F. longifundum at 1200 µg/mL.
  • Ergosterol content was significantly reduced, leading to increased cellular leakage.
  • Severe morphological and ultrastructural damage was observed under scanning and transmission electron microscopy.
