Selecting mixtures of PGPR for biological control of multiple plant diseases
Many plant pathogens (Pythium, Rhizoctonia solani, Fusarium spp., Xanthomonas spp. and Pseudomonas spp.) have a wide host range, a cosmopolitan distribution, and the capacity to cause tremendous economic damage. Biological control using specific PGPR strains has been demonstrated against these pathogens. Typical biocontrol studies evaluate a single PGPR strain against a single pathogen. Our long-term aim is to develop mixtures of PGPR for biocontrol of multiple plant diseases. The underlying hypothesis of this work is that compatible mixtures of PGPR with antagonism to multiple pathogens will provide greater disease suppression than individual PGPR. In this research, we evaluated three collections of PGPR known to have growth promotion and biocontrol potential: Collection 1=318 strains from Pathway, collection 2=140 bacilli strains from Auburn University, collection 3=58 strains from Becker Underwood. Nine pathogens Pythium ultimum, P.
