Abstract/Contents: | Presents a study to "examine the development, including possible apothetical production, of the dollar spot pathogen in creeping bentgrass greens and fairways when present in leaf or root tissue or as isolated stroma, and to determine the length of survival of the pathogen in infected tissue or as stroma." The study will also "measure the genotypic variation of the pathogen from similar and diverse geographical locations using RAPD analysis and anastomosis groupings." Reports that although "the basic biology of the disease still is not known, there at least two stages of the life cycle." Also reports that "the dollar spot lesion itself does not contain living hyphae, but rather that the pathogen is located outside of the lesion." Notes that "resistance to pesticides appears to differ substantially between strains." This three-year study began in 1998. |

USGA Summary Points: | The basic biology of the disease still is not known (i.e., unable to determine where it survives or the form). There are at least two stages of the life cycle: one is a slow-growing quiescent phase and the other is a pathogenic and aggressive phase; however, the quiescent phase could not be detected in sites where the pathogen killed turf. The dollar spot lesion itself does not contain living hyphae, but rather that the pathogen is located outside of the lesion. Genotypic variation of the pahtogen from similar and diverse geographical locations was determined using RAPD analysis and anastomosis grouping. Resistance to fungicides appears to differ substatntially between strains. |
