Overview

In vitro and in vivo evaluation reveals Cymbopogon winterianus nanoemulsion reduces anthracnose in papaya, indicating potential for sustainable postharvest disease management.

Key Points

To develop, characterize, and evaluate essential oil nanoemulsions from Cymbopogon flexuosus, Cymbopogon winterianus, and Zingiber officinale to control postharvest anthracnose in papaya and banana.
Prepared nanoemulsions using low-energy emulsification and evaluated droplet size, polydispersity index, zeta potential, and chemical composition via GC/MS.
Conducted in vitro mycelial growth inhibition assays against Colletotrichum plurivorum and Colletotrichum musae, followed by in vivo disease severity and physicochemical quality assessments on inoculated papaya and banana fruits.
Nanoemulsions displayed nanometric droplet sizes ranging from 95.9 to 171.3 nm, low polydispersity (< 0.28), and zeta potentials between −4.3 and −24.5 mV.
C. winterianus and C. flexuosus formulations inhibited in vitro mycelial growth of both pathogens at concentrations between 0.03% and 0.07% essential oil.
In fruit assays, C. winterianus nanoemulsion produced a concentration-dependent reduction in papaya anthracnose severity with no visible lesions at 0.16% without altering physicochemical quality, but showed no disease reduction in bananas.
