Abstract
Background: Angiospermic plants have been recognized as the store house of several biologically active substances. They also store and emit volatile substances like essential oils which diffuse out in the vicinity. There are enough references to believe that essential oils, extracted from plants have enough antimicrobial potentialities and at the same time are largely non- toxic to humans as compared to synthetic antimicrobial substances. Besides being antimicrobial in nature, such substances are generally biodegradable, non- pollutive and can easily be procured. Objective: The present project was undertaken to evaluate the fungitoxic efficacy of the volatile essential oil of Myristica fragrans and its active constituent ‘Eugenol’ against fungal pathogens of paddy plants viz., Rhizoctonia solani, Pyricularia oryzae and Cochliobolus miyabeanusin order to explore the possibility of their use as an alternative to synthetic fungicides. Various fungitoxic properties like nature of fungitoxicity, effect of temperature and storage on the antifungal efficacy of the volatile essential oil and its active constituent are also studied. Materials and Methods: The volatile essential oil was extracted from sterilized dried arils of Myristica fragrans by hydro-distillation process in a Clevenger’s apparatus. The fungitoxicity of the essential oil and its active constituent against test fungi was determined by Inverted Petri-Plate Technique. Results: The volatile essential oil and its active constituent ‘Eugenol’showed strong toxicity against test fungi. The toxicity of the oil did not change when subjected to high temperature conditions and variable periods of storage. Both volatile oil and its active constituent showed a wide range of antifungal spectrum. Conclusion: The study, thus clearly reveals that the volatile essential oil of Myristica fragrans and its active constituent ‘Eugenol’ have strong fungitoxic activity and can be used to control fungal diseases of paddy plants.
