Fig. 20. Spring dead spot severity in response to fungicide applications. Fungicides were applied at high label rates in September and October of 2002 and 2003. Data were collected in May of 2003 and 2004 at 100% green-up of the bermudagrass turf. Data are averaged across 4 application methods, which did not significantly impact disease control. Bars containing the same letters are not significantly different according to the Waller-Duncan k-ratio t-test. From Butler and Tredway, 2006 (4).
