Abstract

Seven essential oils – Rosemary, Wintergreen, Teatree, Patchouli, Palmarosa, Geranium and Eucalyptus were used to determine the in vitro antifungal activity on Phomopsis azadirachtae. This organism is responsible for the destructive die-back disease of neem. The oils mentioned above were screened using the food poisoning technique. All the seven oils showed considerable antifungal activity against P. azadirachtae. After the conduction of the tests using the oils, the results were such that Wintergreen, Geranium and Palmarosa showed complete or 100% inhibition of mycelial growth at a concentration of 2500 ppm. Among the oils tried, Palmarosa proved to be most potent showing complete inhibition of mycelia at 500 ppm. This really suggests that plant sources possess antifungal activity and can be effectively used to treat and manage plant diseases thereby circumventing the fungal spread in our environment.
