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%). |
