Endophytes are known for their antifungal activity. Aspergillusflavus is a dominant endophyte isolated from stem and leaves of Acacia nilotica. .Aspergillusflavus screened for their antifungal activity against some plant pathogenic fungi. Antifungal activity was checked by using Dual culture method on PDA medium. The zone of inhibition was calculate. The maximum inhibition was recorded against Rhizoctoniasolani followed by Fusariumsolani, Aspergillusniger and minimum inhibition was recorded against and Pythiummyriotylum.
