| Abstract/Contents: | "Fusarium patch, caused by Microdochium nivale, is prevalent on cool-season turfgrass in the Pacific Northwest. Fungicide applications, in addition to cultural strategies, are used to manage fusarium patch. Utilising naturally occurring micro-organisms to suppress turf disease would provide an environmentally acceptable alternative to repeated fungicide applications. The focus of this study was to screen micro-organisms for fusarium patch suppression on turfgrass under greenhouse conditions. Cone-tainers (3.8 cm diameter) packed with sterile vermiculite were seeded with Agrostis stolonifera, Poa annua var. annua and Lolium perenne at 160, 43 and 16 seeds per cone-tainer, respectively, and placed on a mist bench. Weekly fertilisation of 12.2 kg N ha⁻¹ was supplemented with 2 applications of 48.8 kg N ha⁻¹, 9 and 5 days prior to pathogen inoculation. Three weeks after germination, bacterial suspensions of 4 fluorescent pseudomonads were applied to the turfgrass in a RCBD with 5 replications. Colony forming units were counted 24 or 48 hours after plating. Plants were inoculated with a M. nivale spore suspension and three weeks after inoculation, plants were rated for disease. Antagonists 2-79 and Q2-87 suppressed M. nivale on Agrostis stolonifera compared to the uninoculated control. Q2-87 also suppressed M. nivale on Poa annua compared to the uninoculated control." |
