Abstract/Summary

A total of twenty bacterial isolates were obtained from soil samples and roots of Cenchrus echinatus (kawit-kawitan). Seven isolates designated as KS7, KR2, KR3, KR4, KR5, KR7 and KR10 were found to be positive for herbicidal activities against Cenchrus echinatus. On the other hand, of the twenty bacterial isolates obtained from soil samples and roots of Mimosa pudica (makahiya), thirteen isolates designated as MS2, MS3, MS4, MS5, MS9, MR1, MR3, MR4, MR5, MR6, MR7, MR8 and MR10 were able to suppress the seed germination activity of Mimosa pudica. These bacterial isolates were assessed in terms of their inhibitory effect on the seed germination activity of a commercially important crop, Phaseolus (MONGGO). Nine isolates designated as KS7, KR2, KR3, KR4, KR5, MS2, MS3, MS4, and MR7 did not retard the germination of the Phaseolus seeds. Hence, these bacterial isolates can be used as effective biological control agents.
