| Abstract/Contents: | "Tall Fescue (Festuca arundinacea) is a commonly utilized turfgrass in the temperate and transition zone areas of the United States. It establishes quickly, requires moderate amounts of nitrogen, and is resistant to most diseases. However, during hot humid summers, tall fescue is under stress and is susceptible to Rhizoctonia solani infection. The resulting disease, referred to as brown patch, causes turf thinning, leading to encroachment from weeds such as bermudagrass (Cynadon dactylon). Cultural practices such as fertility and mowing height may impact bermudagrass encroachment and brown patch disease in tall fescue. Improved brown patch control may result in lower weed infestations. Two mowing heights (5 and 10 cm), three levels of fertility (49, 171, and 220 kg of nitrogen annually per hectare), and preemerge herbicide application (ronstar or no herbicide applied in 2009 only) were evaluated in an established stand of 'RTF' tall fescue. Three plugs of common bermudagrass were planted in each plot in May 2008. Data collected monthly included weed composition and density, bermudagrass diameter, brown patch severity, and turf quality. The experiment was repeated in May of 2009. Mowing height had a significant effect on bermudagrass in year one and year two. A higher mowing height resulted in less bermudagrass encroachment. Fertility did not have an effect on bermudagrass diameter. In July and August, southern crabgrass (Digitaria ciliaris) density was much greater in the 5 cm mowing height plots. Tall fescue cover was significantly reduced in the 5 cm mowing treatment due to weed competition but was acceptable at the 10 cm height. Higher fertility resulted in increased brown patch severity. However, these plots recovered quickly when weather was cooler and dryer. The same trends were observed in year two, though incidence of brown patch was greater in year two due to the increased precipitation." |
