Sacred basil (Ocimum sanctum) is contains active ingredients such as alkaloids, enzymes and other inorganic elements. With a view to assess the fungitoxicity of Ocimum sanctum against the fungal pathogens, studies were conducted on the fungitoxicity of Ocimum sanctum against fungal pathogens. It is concluded that all the four forms ., crude (10%), powdered (10%), boiled (10%) and ethanol (1%) extract of Ocimum sanctum leaf significantly inhibited the growth of the test fungus viz., Rhizoctonia solani, R. bataticola, Phoma sorghina, Colletotrichum gloeosporioides, Fusarium oxysporum . pallidoroseum, F. oxysporum . ciceri, Sclerotium rolfsii, Sclerotinia sclerotiorum, Alternaria solani and A. alternata, but none of the forms could absolutely inhibited the growth of any one of the test fungus. A concentration of effective form was standardized. The results revealed that all the four forms of Ocimum sanctum leaf extracts significantly inhibited the growth of all above test organisms but none of the forms could absolutely inhibited the growth of any one of the test fungus. | Antifungal activity of leaf extracts of ocimum sanctum against fungal pathogens
