Abstract

Brown spot disease is the most serious rice disease due to its destructive nature, wide distribution and presence of several physiological races of the organism. In Asia, the disease has been recorded to reduce crop yields vary broadly from 6-90%. The application of endophytic fungi is reported to increase plant resistance from the secondary metabolites produced. The resulting metabolites are synthesized compounds to maintain their existence in interacting with the environment. The aim of this study was to obtain endophytic fungi of rice plants that were able to suppres Helminthosporium sp. pathogens. Isolation of endophytic fungi was carried out from the roots, peniles, leaves and leaf sheath of rice plants. Identification of endophytic fungi was based on their macroscopic, microscopic characters and molecular identification. Endophytic fungi that had the highest inhibition were T. asperellum, F. nirenbergiae, and F. oxysporum as indicated by the in vitro antagonism test. T. asperellum, F. nirenbergiae, and F. oxysporum also produced IAA hormone between 1.8 to 4.365 mg/L.

Abstract

Chili pepper (Capsicum frutescens L.) is a horticultural commodity that has high economic value and has the potential as an export commodity. One of the factors causing the decrease in productivity of chilli pepper is anthracnose caused by C. gloeosporioides. Consequently, plant-based fungicides might be served as eco-friendly alternatives to control C. gloeosporioides. This study aimed to invesitigated the effect of plant extracts from clove flowers, fennel seeds, basil, sweet basil, and citronella on growth inhibition of C. gloeosporioides in-vitro and in-vivo. Data were analyzed using Analysis of Variance (ANOVA). The five plant extracts were able to inhibit the growth of the pathogen C. gloeosporioides in vitro and in vivo. The highest inhibition of the pathogen C. gloeosporioides was basil extract treatment in-vitro compared to the control treatment. The in-vivo treatment, the lowest growth of C. gloeosporioides in fennel extract and was significanly different compared to the control treatment.
