| Abstract/Contents: | "Dollar spot of turfgrass, caused by Sclerotinia homoeocarpa F.T. Bennett, is one of the most common and most costly diseases of high input turfgrasses, particularly on golf courses. A molecular detection method for S. homoeocarpa has been developed through the synthesis of species-specific primers for use in conventional and quantitative PCR. Additionally, Internal transcribed spacer (ITS) region sequence analysis has identified two genetically distinct types of isolates; a Type l group, which consists predominately of C3 isolates (collected from cool-season turfgrass hosts), and a Type II group, comprised of only C4 isolates (collected from warm-season turfgrass hosts). Both group type isolates have been found to coexist in the same locale, and tend to infect the preferred host type. However, in northern areas, C4 isolate analysis 45 indicates that these isolates group genetically with Type l isolates. Therefore, the purpose of this presentation is to determine the extent at which S. homoeocarpa isolates infect and cause disease on cool and warm-season grasses that co-inhabit specific locations, the extent to which warm-season isolates have moved north, and the ability of these isolates to cause disease on other host types under specific environmental conditions. Preliminary results indicate that C3 isolates cause higher disease severity on both host types under varying environmental conditions. This is of importance as warm-season species, such as bermudagrass, are being used more widely in northern locations." |
