Summary : One-hundred eighteen putative Bacillus strains isolated from healthy corn roots obtained from Baguio, Bukidnon, La Union, Los Banos, Misamis Oriental and Nueva Ecija were evaluated for antagonistic activity by co-cultivation against Diplodia macrospora Earle (DM), Fusarium moniliforme J. Sheld. (FM) and Phythium graminicolum Subr. (PG) causing seed rot and post-emergence damping-off in corn. Of these isolates evaluated, only three isolates were found antagonistic to the test pathogens: Ba-UPR 30 on PG; BA-NER 1 and Ba-NER 23 on DM and ; BA-NER 1, Ba-NER 23 and Ba-UPR 30 on FM. Both agar-diffusable and volatile metabolities toxic to the pathogens were produced by te antagonists. Rhizoctonia solani (RS) from corn was also found sensitive to the antagonists.
