Abstract/Contents:"Field plots of 'Raleigh' St. Augustinegrass [Stenotaphrum secundatum (Walt.) Kuntze] were used to determine efficacy of fungicide sprays for controlling the Gray Leaf Spot disease. Fungicide treatments were initiated on 25 September 1990, and continued over a 7-week period on intensively watered and fertilized plots. Symptoms of Gray Leaf Spot were observed 3 weeks after initiation of the study, and leaf spot severity data were taken after 30 days. Of 28 fungicide treatments tested on St. Augustinegrass, the highest disease ratings on replicate plots were on the untreated control plots (31%). Field plots treated with Daconil 2787 4F(4 oz), Vorlan + Fungo 25W(1 oz + 1 oz), Chipco 26019 50W(2 oz), ASC66518-c 82.5 FG(4 oz), Fungo Flo 46.2 E(2 oz), and ASC66900 (4 and 8 oz) or ASC66608 (5 and 7.5 oz) sustained 0-10 percent leaf spot disease symptoms."
