| Abstract/Contents: | "Since 1995, rapid blight disease has caused extensive and costly damage to annual and rough bluegrass, perennial ryegrass, and, occasionally, to creeping bentgrass in the southeastern and western United States. Researchers at Clemson University are investigating this disease with the goal of understanding its geographic distribution, host range, and biology and epidemiology. To date, their findings include: Rapid blight disease has been shown to be caused by a relatively obscure microorganism known as Labyrinthula, cingle-celled [single-celled] organisms that occur in net-like aggregations when growing in culture. When it emerges on golf courses, rapid blight symptoms appear as irregular shaped patches of yellow (chlorotic) or brown (necrotic) turf ranging from 6 inches to 6 feet in diameter. The disease has been identified on more than 100 golf courses in 11 western and southeastern states including California, Nevada, Utah, Arizona, Colorado, Texas, Louisiana, Florida, Georgia, North Carolina, and South Carolina. Epidemics of rapid blight have been associated with high salinity irrigation water and soils. Forty-nine different grass cultivars representing a range of cool-season grass species were tested for susceptibility to rapid blight. Mean percent disease ranged from 0.63% in the slender creeping red fescue `Dawson' to 95% in the crested wheatgrass `Ephriam'. The most tolerant grass species to rapid blight were the fescues, creeping bentgrasses, and alkali grasses. With the exception of the creeping bentgrass and other bentgrass species (colonial, Idaho, redtop, and velvet) were all highly susceptible to rapid blight." |
