The basic aim of the investigation was to screen the potential of Trichoderma harzianum for bio suppression of Rhizoctonia solani f. sp. sassaki, the causal agent of banded leaf and sheath blight of maize which is one of the most destructive diseases of Bihar. The disease severity ranging from 30.30 to 80.46 per cent and gaining the economic importance now a day. Maize (Zea mays L.) is one of the most important cereal crops in the world agricultural economy as food, feed and industrial products. It is a miracle C4 crop and has a very high yield potential. There is no other cereal, which has such an immense potentiality and thus is rightly called queen of cereals. In India, maize is grown in almost all the states. It is fourth in area next to rice, wheat, and sorghum, but third in production. It is not only utilized for direct human consumption but also for livestock and poultry feed. Trichoderma harzianum was evaluated for its antagonistic potential against Rhizoctonia solani f. sp. sasakii in vitro condition by employing dual culture technique. The outcome of testing revealed that in dual culture, after 72 hours of incubation, Trichoderma started to overgrew the pathogen colony and in 144 hours Trichoderma fully covered (100 %) the pathogen colony and totally inhibited sclerotial formation. The mechanism of antagonism was hyphal coiling and penetration of the hyphae of Trichoderma in the hyphae of host fungus.

Keywords: Trichoderma harzianum, Rhizoctonia solani and Antagonism.
