This study was conducted to evaluate the antagonistic potential of volatiles emitted from seven Trichoderma spp.against 4 major rice diseases and to investigate their role in enhancement of growth and vigour of rice plants. Isolates were identified based on both morphological characteristics as well as molecular assay. Their biocontrol potential was evaluated and T. erinaceum completely inhibited the growth of Pyricularia oryzae and Bipolaris oryzae. It also inhibited growth of Ceratorhiza oryzae-sativae and Rhizoctonia solani by 64 and 50%, respectively. Sandwich plate method showed that volatiles emitted from T. erinaceum could reduce the mycelial growth of all four pathogens. GC-MS analysis indicated emission of 6-Pentyl- 2H-pyran 2-one from T. erinaceum in large quantity. Seed treatment with Trichoderma enhanced vegetative and reproductive growth of rice cultivar, Sahbhagidhan. Over-expression of defense enzymes like catalase and superoxide dismutase in shoot and peroxidase in both root and shoot were observed in Trichoderma treated plants. Results of this study suggest that T. erinaceum obtained from the rice rhizosphere can be used as a potential biocontrol agent against major rice diseases and as a growth inducer. It can also be utilized as an efficient source to produce 6-Pentyl-2H-pyran-2-one for further use. Not Available |
