Ozone (O3), one of the most powerful oxidants known, is phytotoxic at high levels in the troposphere, or ground-level. Effects of acute ozone exposure for two consecutive days was examined on Bermudagrass (Cynodon dactylon), centipedegrass (Eremochloa ophiuroides), zoysiagrass (Zoysia japonica), St. Augustinegrass (Stenotaphrum secundatum), Liriope muscari ‘Big Blue’, Liriope muscari ‘Aztec’, and Ophiopogon japonicus. Zoysiagrass, St. Augustinegrass, Liriope muscari ‘Big Blue’ were used in the second study based on the differential responses found in the study. Ozone induced severe visual damage to St. Augustinegrass with symptoms appearing as chlorotic streaks. St. Augustinegrass and Liriope muscari had a significant reduction in …
