| Abstract/Contents: | "The purpose of this study was to determine the efficacy of various herbicides and combinations for postemergece control of annual bluegrass in non-overseeded bermudagrass turf. Annual Bluegrass is native to Europe, but now found on every continent. Due to its prolific seed production, competitive growth habit, poor heat and disease tolerance, annual bluegrass disrupts the appearance and uniformity of a turf stand. For these and other reasons, annual bluegrass is a very troublesome bunch type grassy weed, in most turf situations. A study with seventeen treatments was initiated February 17, 2012, with rating dates on February 25, March 10, March 22, and April 7 which corresponded to 8, 22, 34, and 50 days after treatment (DAT), respectively. Treatments included: Reward 2L @ 0.5 lb ai/a; Roundup Pro 4L @ 0.625 lb ai/a; Quick Pro 76WG @ 1 lb ai/a; Finale 1.0SC @ 1.5 lb ai/a; Tranxit 25DF @ 0.03 lb ai/a; Certainty 75DG @ 0.06 lb ai/a; Monument 75DG @ 0.03 lb ai/a; Katana 25DG @ 0.047 lb ai/a; Revolver 0.19SC @ 0.025 lb ai/a; Princep 4L @ 1 or 2 lb ai/a; Kerb 50 WP @ 1.5 lb ai/a; SureGuard 51 WDG @ 0.38 lb ai/a; Xonerate 70WDG @ 0.022 lb ai/a; Roundup Pro 4L + Simazine 4L @ 0.3125 and 1 lb ai/a; Roundup Pro 4L + Ronstar 3.2L @ 0.625 and 3 lb ai/a; and Celsius 63WDG @ 0.1628 lb ai/a. A follow-up study, containing four additional treatments, was initiated March 6, 2012, with rating dates on March 10, March 22, and April 7 at 4, 16, and 32 days after treatment, respectively. Treatments included: Celsius 63WDG @ 0.198 lb ai/a; Tribute Total 60.51WG @ 0.038 lb ai/a; Tribute Total 60.51WG @ 0.076 lb ai/a; and Tribute Total 60.51WG @ 0.24 lb ai/a. All treatments were applied only once in both studies. The studies were conducted near Clemson University in a 'Tifway' bermudagrass field, irrigated and maintained under fairway conditions, and heavily infested with annual bluegrass. Applications were made using a CO^DoA powered sprayer calibrated at 20 GPA. Three treatment replications were applied on 2x2 meter plots, using a randomized complete block design. Visual ratings evaluated percentage control of annual bluegrass. Ratings were based on a 0-100% scale. 0% indicating no control and 100% indicating complete control. ANOVA was evaluated with alpha at 0.05. On the April 7, 2012 rating date, ten treatments provided greater than 95% control: Roundup Pro 4L @ 0.625 lb ai/a at 99%; Finale 1.0SC @ 1.5 lb ai/a at 98%; Tranxit 25DF @ 0.03 lb ai/a 96%; Revolver 0.19SC @ 0.025 lb ai/a at 99%; Princep 4L @ 2 lb ai/a at 100%; Kerb 50 WP @ 1.5 lb ai/a at 98 %; Roundup Pro 4L plus Ronstar 3.2L @ 0.625 and 3 lb ai/a at 99%, at 50 DAT respectively. Tribute Total 60.51WG @ 0.038 lb ai/a; Tribute Total 60.51WG @ 0.076 lb ai/a; and, Tribute Total 60.51WG @ 0.24 lb ai/a all provided >= 99% control at 32 DAT (April 7, 2012). Roundup treated plots had some early temporary turfgrass damage but fully recovered by the last rating date. Repeat applications and screening of additional products will be continued in the future for timing and control of annual bluegrass in non-overseeded bermudagrass." |
