Abstract
The biocontrol potential of Bacillus spp. clearly indicated by several authors are presented crop wise. The understanding of mechanism of action of Bacillus spp. against phytopathogens is essential to support their biocontrol potential. In this regard the various mechanism of action of Bacillus is elaborately discussed with suitable subheadings along with their plant growth promoting ability. The available literature presented below as review strongly emphasized their distinct biocontrol potential coupled with plant growth promoting effect through their various behavioral, biological, biochemical, induction of resistance, role of antimicrobial peptide genes etc.
Keywords: Antibiosis, antimicrobial peptide genes, Bacillus, biocontrol potential, mechanism of action
