Description Not Available
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.
