Abstract/Contents:An investigation was initiated to assess the effects of atmospheric sulfur dioxide on St. Augustinegrass. Four cultivars of St. Augustinegrass were included in this study--Floratam, Raleigh, Seville, and Texas Common. Two distinct levels of exposure were utilized. In the case of acute exposure, the four cultivars were exposed 1.0 ul liter-1 of SO2 for 10 hours per day for 4 consecutive days. In the case of the longer term lower level chronic exposure, the St. Augustinegrass turfs were exposed to .02 ul liter-1 of SO2 for 4 hours per day, 6 days a week for 5 weeks. Floratam was the most susceptible to injury, Texas Common ranked intermediate, and both Raleigh and Seville were the least susceptible to acute exposures to sulfur dioxide. In the care of longer lasting, low level chronic exposures, the St. Augustinegrasses proved relatively resistant to sulfur dioxide exposure. Preliminary experiments with bermudagrass and zoysiagrass revealed that these two species are even less susceptible to sulfur dioxide injury than St. Augustinegrass.
