Abstract/Contents:Presents a study conducted to "evaulate the effects of mowing heights alone and in combination with frequent application of fungicides for improving the root health and turf quality of the ultradwarf bermudagrass during the summer and fall months, and to determine which fungal pathogen(s) might be associated." Results include "two months after the beginning of the first fungicide application, there was an 18% reduction in root necrosis between the fungicide treatments and the control in August. A 17 to 32.6% reduction was observed to occur from September to December. A 12.5% reduction in root necrosis between the two mowing heights was observed in September, and occurred again in November." Also states that "twenty-one genera of fungi were isolated from roots, leaves and whole plants from both treatments over a six-month period. Several of these fungi are known to be pathogenic to turf and included species of Bipolaris, Colletotrichum, Curvularia, and Rhizoctonia." Concludes that "overall, scheduled applications of fungicides were very effective in enhancing the quality of 'Champion' during the summer and fall months. Although increasing mowing height was not as effective as fungicides, mowing heights + fungicide applications might help provide answers to understanding the decline of ultradwarf bermudagrass by supressing root necrosis and enhancing turf quality."
