Abstract/Contents:"The goal of this project was to develop practical biological control systems to manage some important turfgrass diseases. Our approach was to introduce individual microbial antagonists as well as complex mixtures of antagonists through top-dressing applications....Results of this study have, in part, verified our 1988 results and have clearly indicated the potential to biologically suppress Dollar Spot on creeping bentgrass putting greens with topdressing applications of microbial antagonists, organic fertilizers and composted organic wastes. These practices are now being acceptingly incorporated into golf course disease management programs. In as little as two years, the industry has gone from no turfgrass disease biological controls to their widespread use as a direct result of our work. This research has demonstrated that biological forms of disease control are practical, can provide control as good as currently used fungicides, and can provide control for at least one month which is currently as good as any fungicide on the market....It is apparent from our work that composted materials vary not only in their degree of disease suppressiveness, but also in the spectrum of diseases control. This is likely due to a number of microbiological factors inherent to the compost itself, the existing turfgrass ecosystem and the natural sensitivity of pathogen populations to microbial antagonism. Our research in the future will be directed toward understanding many of these aspects as they relate to the performance of biological controls."
