Abstract

Strains of Stenotrophomonas maltophilia and a related bacterium, proposed as Lytobacter mycophilus gen. nov., sp. nov., are capable of controlling summer patch, a turfgrass disease caused by Magnaporthe poae. Strains of these bacteria produce an abundance of extracellular enzymes that have the potential to degrade fungal cell walls, and are capable of colonizing the turfgrass rhizosphere. Growth chamber studies indicate repeated application of S. maltophilia improves disease suppression compared to standard applications. S. maltophilia populations are reestablished above 107 colony forming units/g rhizosphere sample following each repeated application, suggesting these higher populations are critical for disease suppression. Field studies indicate that S. maltophilia populations can be established in turfgrass at these levels, providing support that disease control in the field can be achieved.
