Abstract/Contents:"Isolates of bacteria in the genus Pseudomonas and of actinomycetes in the genus Streptomyces are being evaluated for their ability to control infection of grasses by the dollar spot (Sclerotinia homoeocarpa) and leaf spot (Bipolaris sorokiniana) pathogens. The evaluation process will include laboratory bioassays to determine biocontrol activity and field evaluation to determine the potential for control in the field. Preliminary laboratory studies have established biocontrol activity against dollar spot in three isolates each of Pseudomonas and Streptomyces. The isolates of both organisms substantially decrease the development of dollar spot infection over a 3 day period. The average decrease in disease (measured as loss of chlorophyll and yellowing) by the six isolates is 97.5%. The Pseudomonas species are less active in controlling leaf spot, decreasing disease by an average of 81%. One isolate of Streptomyces, however, has almost completely prevented leaf spot in preliminary studies. The studies conducted to date are preliminary and the potential control activity found in laboratory bioassays has not been evaluated in the field. Field studies are planned for the summer of 1991 to determine the potential use of these microbes for controlling dollar spot and leaf spot in the field. *This research is being supported in part with a grant from the Soil Technologies Corporation."
