Abstract
The present studies were undertaken to investigate the effect of sea weed extracts for the management of Brown spot in rice caused by Bipolaris oryzae. Among the sea weed extracts, seed treatment with Sargassum wightii recorded maximum seed germination, shoot and root length and maximum vigour index followed by S.muticum when compared to control. Whereas, the five sea weed extracts tested as foliar spray, S. wightii at 20 % concentration was the most effective over the other extracts followed by S. muticum at 20 % in reducing disease incidence as compared to control and increases the grain yield. Also, the data indicated that the disease incidence was minimum and the maximum yield was recorded in plots sprayed thrice with S. wightii @ 10 % conc. at 15, 30 and 45 DAT, followed by plots receiving two sprays at 15 DAT and 30 DAT which were statistically at par.
