Abstract

Pomegranate is widely grown fruit in many regions of the world. It is regarded as ‟Fruit of Paradise”. Anthracnose caused by the fungal pathogen Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. is one of the limiting factor for low productivity of Pomegranate. Hence, in vitro evaluation of eight essential oils were carried out against Colletotrichum gloeosporioides (Penz.) Penz. and Sacc. causing anthracnose of pomegranate. Among these oilsˏ Thyme oil (Thymus vulgaris) and Clove oil (Syzygium aromaticum) had shown the best result in controlling the fungal growth. Savory oil (Satureja hortensis) and Cinnamon oil (Cinnamomum verum) are considered as secondary best oils followed by Citronella oil (Cymbopogon) and Mint (Mentha) oils. Whereas, Tea tree oil (Melaleuca alternifolia) and Eucalyptus oil (Eucalyptus globulus) had shown poor results in fungal growth control.
