Abstract:
Grain discolouration is an important constraint in reducing productivity of rice. Curvularia lunata and Fusarium moniliorme are two important pathogens responsible for it. An in vitro study was undertaken to test the efficacy of different bio control agents against these pathogens. It revealed from the experiment that all the antagonists recorded a significant inhibition over control. Trichoderma harzianum recorded maximum mycellial inhibition of 90% followed by Trichoderma viridae (strain2) (87.44%) and T. viridae (strain1) (83.77%) against Curvularia lunata. In case of Fusarium moniliforme, maximum inhibition was recorded in Trichoderma viridae (strain2) (65%) followed by T. viridae (strain1) (52%).
