Abstract: Effect of seed pelleting with Stachyboays atra, Memnoniella echinata and Rhizobium meliloti on colonization of mungbean and cowpea roots by Macrophomina phaseolina, Rhizoctonio solani and Fusarium spp., was studied. A combined use of S. atra and R. meliloti was more effective in suppressing colonization of M. phaseolina and Fusarium spp., on mungbean and R. solani on cowpea roots than their separate use. Colonization of cowpea roots by all the three pathogens, and of mungbean roots by Fusarium spp., was greatly suppressed by a combined use of M. echinata and R. meliloti than their separate use. Use of S. atra showed greater phytotoxicity on cowpea as compared to mungbean.
