Abstract

ABSTRACT

Anthracnose disease caused by Colletotrichum spp. leads to significant losses
in bird’s eye chilli production, including reduced fruit quality, lower yield, and
increased production costs. Although synthetic pesticides are widely used for
disease management, their prolonged application raises concerns regarding
environmental sustainability and food safety. This study aimed to evaluate the
antifungal potential of citronella essential oil, in both free and nanoencapsulated forms, against Colletotrichum spp. The experiment was arranged
in a Completely Randomised Design (CRD) with treatments consisting of
citronella essential oil at concentrations of 0.125% and 0.063%, either
encapsulated or non-encapsulated, tested under in vivo and in vitro conditions.
Parameters observed were incubation period, disease intensity, inhibition
percentage, colony appearance, and hyphal morphology. Data were analysed
using ANOVA at a 5% significance level, followed by Duncan’s Multiple Range
Test (DMRT) when significant differences were detected. Application of
0.125% citronella essential oil effectively delayed incubation (6.05 DAI),
resulted in a disease intensity of 45%, and achieved the highest in vitro
inhibition (92,21%) until 10 DAI, outperforming Propineb 70 WP and other
treatments. Colony morphology remained generally similar, but notable
differences in hyphal fate were observed, including lysis, shrinkage, curling,
and unbranched growth. These findings indicate that citronella essential oil is a
potential alternative for chilli anthracnose management.

Keywords: Antifungal activity, Cymbopogon nardus, disease intensity,
incubation period.
