Implication

Experimental study demonstrates vapor-phase Cymbopogon citratus essential oil controls Botrytis cinerea in horticultural products, indicating a safe alternative to chemical fungicides.

Key Points

The study aims to explore the antifungal efficacy of vapor-phase Cymbopogon citratus essential oil against Botrytis cinerea and powdery mildew, focusing on its mechanism of action.
Developed vapor-phase antifungal strategy using GRAS-compliant essential oil
Conducted GC-MS analysis to identify bioactive compounds
Assessed antifungal activity via EC50 and MIC values against Botrytis cinerea
Performed mechanistic analysis to evaluate membrane disintegration and enzyme inhibition
Conducted commercial-scale trials on cherry tomatoes to evaluate decay and quality preservation.
Cymbopogon citratus essential oil exhibited an EC50 of 14.69 µg/mL and MIC of 7.81 µg/mL against Botrytis cinerea
Demonstrated a tripartite mode of action with significant membrane disintegration and enzyme suppression
Commercial fumigation reduced cherry tomato decay by 81.9–92.6% over 28 days while enhancing firmness and nutritional quality
Also showed strong inhibition of rubber tree powdery mildew with an EC50 of 3.19 µg/mL, indicating broad-spectrum effectiveness.
