Potato soft rot is the bacterial disease of this crop which happens more frequently in Cuba causing economic losses. In this paper, the in vitro antagonist effect of different Bacillus strains against Pectobacterium carotovorum, Pectobacterium atrosepticum and Dickeya chrysanthemi was estudied using diffusion in agar method. Except B9, all the strains had inhibitory effect on the growth of all the phyopathogenic bacteria analyzed. B1 and B2 strains showed the best antagonist effects, being achieved in both cases inhibition halos of considerable size. The results suggest that some of these strains could be considered as potential agents of biological control of the soft rot. [ABSTRACT FROM AUTHOR]
