ABSTRACT
In the present research studies, the antagonistic microorganisms were tested for their efficacy in inhibition of growth of C. lunata. Among the different bio-agents, Bacillus subtilis (97.77%) followed by fungal bio-agent Trichoderma viride (96.44%) and T. harzianum (93.50%) were found to be effective. Seed treatment with T. viride was found to inhibit the C. lunata mycoflora association with grain discolouration with 90.05 per cent germination and 1170.00 vigour index followed by Bacillus subtilis (87.99%) germination and 989.11 vigour index,
Key words :
Bio-agents, Curvularia lunata, grain discolouration, oryza sativa, rice.
