In Vitro Evaluation of PGPR Strains for Their Biocontrol Potential Against Fungal Pathogens

摘要: Crop protection has become a basic requirement of the sustainable agriculture to ensure increased crop production. Biological control been actively practiced as measure for more than five decades and history biocontrol, its successes failures, have extensively reviewed. Plant growth promoting rhizobacteria (PGPR) are an important group microorganisms, which play major role in biocontrol plant pathogens. All plant-associated microenvironments, especially rhizosphere, colonized high abundances by antagonistic microbes. Between 1 35 % microbial inhabitants show capacity inhibit pathogens vitro various mechanisms that include production antibiotics, siderophores, lytic enzymes, HCN induced systemic resistance. In recent years, popularity agents substantially, extensive systematic research enhanced their effectiveness consistency.
