Abstract
The goal of the current study was to assess
the toxicity and effectiveness of three essential oils against the green peach
aphid, Myzus persicae (Sulzer), which infest yellow daisy plants (Euryops
pectinatus). These oils are neem oil (Azadirachta indica), clove oil
(Syzygium aromaticum), and lemongrass oil (Cymbopogon citratus).
Three replications of each treatment were used in the Completely Randomized
Design (CRD) experiment, which was conducted in a controlled laboratory
setting. Aphid mortality was measured 24, 48, and 72 hours after treatment
(HAT), and essential oils were examined at three doses (1%, 2%, and 5%). Clove
oil showed the highest toxicity among all treatments, recording a mean
mortality of 43.44 ± 3.87% at 5% concentration after 72 hours, followed by
lemongrass oil (39.33 ± 4.41%) and neem oil (36.33 ± 4.03%). The control
treatment showed minimal mortality. ANOVA statistical analysis revealed highly
significant differences among treatments and exposure periods (P < 0.05),
confirming the efficacy of essential oils in aphid management. According to the
study, plant-derived essential oils, particularly clove oil, have strong
insecticidal properties against M. persicae and could be used as
eco-friendly alternatives to synthetic chemical pesticides. Botanical oils can
help to promote sustainable and environmentally friendly pest management in
ornamental and crop plants.
