Abstract/Contents:"Metalaxyl applied at 14.2, 28.4, 56.7 and 85.1 g a.i./93m2 as foliar sprays provided both protective and systemic activity against Sclerophthora macrospora on St. Augustinegrass. All rates of metalaxyl reduced the percentage of diseased leaf blades from greater than 90% on the day of application to 0% 28 days later. Histological examination of S. macrospora-infected leaf blades 7 days after application of metalaxyl showed that the fungicide can eradicate the fungus. Both spring and fall/spring application of metalaxyl in the field controlled downy milew. Fenaminosulf demonstrated little or no control of St. Augustinegrass downy mildew."
