Abstract

Fungal pathogens are responsible for the rot of tomatoes and cause health hazards to consumers as well as economic loss. The aims of this study were to evaluate the efficacy of essential oils from Pimenta racemosa (Mill.) and Mentha x piperita (L.) leaves as plant-based fungicide against Fusarium oxysporum strains associated with tomato rot. The chemical composition of the essential oils was determined by GC-MS analysis. Antifungal effects of essential oils against strain of F. oxysporum obtained from rotted tomato, were evaluated through the determination of Minimal Fungicide Concentration (MFC) and the Minimal Inhibitory Concentration (MIC). Results indicated that β-myrcene (19.48%), chavicol (15.39 %), and eugenol (46.65%) were the major components of the essential oil of Pimenta racemosa (Mill.). L-menthone (17.19 %), menthol (24.79%), and menthofuran (26.78 %) were the major components of the essential oil of Mentha x piperita (L.). Essential oil of Pimenta racemosa (Mill.) exhibited the highest antifungal activity against the growth of Fusarium oxysporum strain tested with a MIC and MFC of 0.75 and 1.25 μl.ml-1 respectively. These results provide an experimental basis for further research on the use of these plant extracts in the development of eco-friendly preservatives against fungi causing rots of tomato in post-harvest.
