Most of the rice diseases are transmitted by seeds which are the important limiting factor getting good quality seeds and good yield. Stored and freshly harvested rice seed of different varieties were collected from Agricultural farm of Orissa University of Agriculture and Technology, Bhubaneswar, Odisha to study the association of different fungal pathogens. The seeds were graded on the basis of intensity of discoloration. Among nine plant products evaluated against the pathogenic fungi Fusarium fujikuroi, Curvurlaria lunata, Helminthosporium oryzae, garlic extract alone and in combination with datura and neem leaf extract completely inhibited the growth of the fungi at 10% and 20% concentration. The biocontrol agents Trichoderma viride and Bacillus subtilis inhibited the growth of F. fujikuroi up to 78.11% and 78.7% respectively. Pseudomonas fluorescens inhibited 74.06% radial growth of H. oryzae which was more than B. subtilis (22.66% inhibition). 52.4% growth reduction was found by T. viride against C. lunata followed by P. fluorescens (51.8% reduction). Propiconazol 0.1%, Carbendazim+Mancozeb0.1%, Carboxin+Thiram 0.2% Tebuconazol 0.1% and copper oxychloride 0.3% completely inhibited the growth of all three pathogens.
