| Abstract/Contents: | "Take-all root rot (TARR) of St. Augustinegrass caused by Gaeumannomyces graminis var. graminis is a major disease problem on landscape in Texas and other states along the United States Golf Coast. In a 1999 survey of St. Augustinegrass lawns in Dallas, TX, we observed TARR yellow patch symptoms on 61% of 70 lawns observed during the month of September. Lack of TARR resistance among commercial St. Augustinegrass varieties prompted this 2001-2003 study of TARR disease occurrence and methods of disease control on St. Augustinegrass lawns. The number of lawns with TARR yellow patch symptoms was increased by higher levels of shade intensity and/or St. Augustine Decline Virus infection during the survey period. Fungicide disease control studies using azoxystrobin were successful for control of TARR following repeated applications of the fungicide in spring and fall. Repeated applications of propiconazole, however, provided no benefit for disease control when used alone or in combination with azoxystrobin. A second approach to disease control explored the use of commercial turf topdressing products, including finely ground manure, and sphagnum peat moss. Little or no long-term disease suppression was observed following applications of non-composted or composted manure products or a bacterial amended manure compost on TARR infected lawns. Similar field experiments using acidic peat moss, however, demonstrated effective control of the disease during two successive years in field studies on residential lawns. Success in TARR disease control was attributed to long term effects of peat moss to provide acidic microenvironments on St. Augustinegrass stolons, which was effective in reducing saprophytic and parasitic activities bu the pathogen." |
