Abstract: Seed discolouration is an important constraint in paddy. It reduces germination, vigour as well as marketability of the produce. There are several pathogens responsible for the seed discolouration. During investigation it was found that, Fusarium moniliforme is responsible for tip discolouration and Curvularia lunata is responsible for base discolouration of seed. For management, eight chemicals were screened against these pathogens in vitro and revealed all the chemicals were significantly inhibit the growth of pathogen. Thiophanate methyl at 0.1% concentration recorded maximum mycellial growth inhibition of Curvularia lunata (92%) followed by tricyclazole at 0.5% (91.80%) where as Copper oxide at 0.2% concentration recorded maximum mycellial growth inhibition of Fusarium moniliforme (90.91%) followed by Carbendazim at 0.1% (90.51%).
