Endophytes are the crucial microorganisms, play a key role as Biocontrol agent. The present paper aims at documenting the effects of Endophytes isolated from Averrhoa carambola L leaf. Three Endophytes were isolated from leaf margins after inoculating it on PDA media plates by Imprint method & identified as Dematiaceous fungi 1(E1), Dematiaceous fungi 2(E2) & Fusarium species(E3) based on morphological & microscopic characters. The potentiality of all three endophytic fungi were checked for its antagonism towards Didymella bryoniae (P1), Aspergillus species (P2), as pathogens respectively by dual culture technique. After an incubation period of 30 days, the Percent inhibition (PI)of pathogen is calculated. The percent inhibition of E1 against P1 & P2 is 40% & 40.6% respectively. E2 against P1 & P2 is 38.6% & 32%, E3 against P1 & P2 is 80.6% & 82.6% respectively. The order of activity is E3P2 > E3P1 > E1P2 > E1P1 > E2P1 > E2P2. The research work concludes that Fusarium species as Biocontrol agent is a promising Endophyte that can supress many pathogens particularly Didymella bryoniae which causes Gummy stem blight of cucurbits by more than 80%.
