Abstract/Contents: | "Rapid blight is a new disease of cool season turfgrasses caused by a species of Labyrinthula. A water-soaked appearance is initially observed in affected turf. Disease often occurs on turf irrigated with high salinity water and in areas of frequent mowing. The effects of salinity of irrigation water and cutting on symptom development were studied in the laboratory. Two-week-old seedlings of perennial rye 'Brightstar SLT' were inoculated with a 2 ^D#x 10-5 cells/ml suspension of Labyrinthula isolated from diseased turf in Arizona. Irrigation water was adjusted to 0.5, 0.8, 1.4, 1.8, 2.3, 2.8, 4.0, 6.0 and 8.0 dS/m by adding artificial seawater. Plants were infected, but not symptomatic, when irrigated with 0.5 dS/m water. At salinities from 0.8 to 8.0 dS/m, symptom development increased as salinity increased. Studies with plants that were cut or not cut prior to inoculation showed that cutting is not required for, but accelerates, symptom development. These findings substantiate field observations that rapid blight becomes increasingly more severe as salinity of irrigation water increases and that disease is exacerbated by mowing." |
