| Abstract/Contents: | "Increasing restrictions on the use of chemical pesticides demands a shift in emphasis from chemical control to alternative disease control methods. One alternative is the biological control of plant disease through the use of "beneficial" microorganisms that are antagonists of disease-causing microorganisms. This is the first year of a project to investigate sites where disease has declined naturally as potential sources of information and biological materials for the development of biological control methods. Increased activity of antagonistic microorganisms may be associated with disease decline expressed at a site over several seasons or within the green, recovered central areas that often appear within brown, symptomatic patches of turf as the disease spreads. Study was begun with a bermudagrass field plot previously inoculated with Leptosphaeria korrae (cause of spring dead spot) at the University of California at Riverside Experiment Station. Disease had spread sufficiently so that green, symptomless patches were obvious in the center of brown, diseased areas, hence, a comparison of microbial profiles from each of these areas could be performed. Thus far, 135 different bacteria and fungi have been isolated from this UCR field plot. These microorganisms are being tested for the ability to reduce growth of several turfgrass pathogens (Leptosphaeria korrae, Sclerotium rolfsii, and Rhizoctonia solani) in culture. Experiments are also underway to test the most promising microorganisms for their ability to reduce disease in the greenhouse. Identification of disease decline sites in California, studies to determine the disease-suppressiveness of turf samples from these sites, and a comparison of virulence of pathogens from these sites are planned for the second half of this project year." |
