Abstract/Contents:"Crabgrass (Digitaria spp.), a seed propagated summer annual grass species, is considered one of the most important weeds in turf management systems. Many studies have been focused on the herbicide control, however, research on the biology and ecology of crabgrass is conspicuously absent, especially, the information on the ecological aspects influencing the infestation in turf. Understanding these factors could lead to improved crabgrass management strategies. The purpose of this study was to determine the effects of open space (gap size), thatch layer and soil temperature on crabgrass infestation in turf. Field experients were conducted in 1996 on a mature stand of turf-type tall fescue (Festuca arundinacea). Experiment A was on a site with a history of heavy smooth crabgrass infestation, and experiment B was on a site without a history of infestation." Includes the results from the experiment and also further discussion.
