Abstract: Neem (Azadirachta indica A. Juss.) is perhaps the most versatile medicinal plant with multifarious uses, as pesticides, insecticides, fungicides, bactericides and also as powerful agent for treating n variety of human ailments and disorders. The fungi toxicity of Azadirachta indica was evaluated against ten fungal pathogens with different leaf extract forms viz., powder form, crude form, boiled form and ethanol form. The results reveals that all the four forms of neem part extracts significantly inhibited the growth of all above test organisms but none of the forms could absolutely inhibit the growth of any one of the test fungus. The boiled extract was found significantly superior over other forms for inhibiting the growth of Rhizoctonia bataticola, Alternaria cyamopsides. Tolyposporium penicillariae and Sclerotinia sclerotiorum. This supports the use of boiled neem leaf extract for the control of these fungi. The growth of both the species of Fusarium, Colletotrichum gleosporioides and Phoma sorghina was more effectively inhibited under its crude form than the other three forms. These suggest the use of crude extract of neem for the control of F. oxysporum f.sp. ciceri, Phoma sorghina, F. oxysporum f.sp. pallidoroseum and C. gleosporioides, while the powdered form of neem leaf extract was found more suitable for the control of Sclerotium.
