| dc.description.abstract | The study was conducted to isolate fungal endophytes from 10 fruit trees namely: custard apple, avocado, cashew, javaplum soursop, guava, jacksruit, mango, star apple and pomelo. A total of 182 isolates were tested in vitro gainst Sclerotium rolfsii. Only 6 EF were selected from preliminary in vitro test and further tested for the 1st trial of dual culture test. Out of the six fungal endophytes, only 3 potential EF showed a significant antagonistic activity and subjected to the 2nd trial of DCT. The potential antagonistic endophytic fungi were Sterile mycelia Sa7Sc1, Sterile mycelia Lk3Sc2 and Aspergillus sp. Sh4Sc2. The highest growth inhibition was recorded by Aspergillus sp. Sh4Sc2 with 66.33% followed by Sterile mycelia Lk3Sc2 with 36.18%. Additionally, zone of inhibition was observed using Sterile mycelia Sa7Sc1 with 9.38mm. Pot experiment revealed that bio-formulation of Sterile mycelia Lk3Sc2 recorded the highest % germination of peanut seeds. Moreover, 0% disease incidence, % damping-off, % post-emergence rotting and % post emergence wilting was also observed on seeds treated with Sterile mycelia Lk3Sc2. Additionally, bioformulation of Sterile mycelia Sa7Sc1 and Aspergillus sp. Sh4Sc2 had 90% and 80% germination with 10% disease incidence accounted to each treatment, respectively. Bio-formulation of Sterile mycelia Lk3Sc2 and Sterile mycelia Sa7Sc1 provided good and vigorous growth of peanut. | |
