Abstract/Contents:Profiles dollar spot, highlighting its biological processes "that affect where dollar spot occurs and how its spreads." Explains that "dollar spot is caused by the fungal pathogen, Sclerotinia homoeocarpa. This pathogen infects both cool season and warm season grasses, and is somewhat unique among the turfgrass pathogens because it is not known to produce spores of any kind." Describes the pattern of occurrence of dollar spot, stating that "over the course of a growing season, the number of dollar spots that occur in an area increases and decreases...Presumably, this is due to environmental conditions that affect the apperance of the disease, the growth and vigor of the host plant, and the virulence of the pathogen. If the pattern changed over the course of the season, the expectation would be to observe a similar change in the semivariance plots." Reports that "regardless of how much disease was present, the overall pattern remained stable." Also reports that "mowers are quite efficient in picking up and retaining tissue that is cut by the mowing unit rather than spreading it downstream." Suggests that "as [researchers] understand more about turfgrass disease biology and spread, management practices can be implemented to improve disease management programs with cultural practices and make chemical applications more efficient and environmentally sensitive." Concludes that "using these techniques it is possible to develop prediction tools that allow a turfgrass manager to better time chemical applications and can ultimately allow managers to target specific areas of the property in a site-specific manner rather than making...blanket applications."
