| Abstract/Contents: | "The purpose of this research was to investigate the safety of Certainty (Sulfosulfuron) to 'Riviera' and 'Princess" seeded bermudagrass and the control of Cocks-comb Kyllinga (Kyllinga squamulata) and Smooth Crabgrass (Digitaria ischaemum). Cocks-comb Kyllinga is a summer annual with bunch type growth that grows in moist areas and can be unsightly on highly maintained turf areas. Smooth Crabgrass is a widely distributed clumping summer annual that produces unsightly seed heads and disrupts turf uniformity. The study was conducted on seeded 'Riviera' and 'Princess' Bermudagrass located on the campus of Clemson University. The plot size for each treatment measured 2.0 m by 3.0 m, with four replications. Treatments were applied using a CO2 backpack sprayer calibrated at 20 GPA. Treatments for the study included: Certainty 75 DF at 1.25 oz/A and Certainty at 2.5 oz/A on July 12, 2010 (21 DAE) and Certainty at 1.25 oz/A and Certainty at 2.5 oz/A on July 19, 2010 (28 DAE). Visual ratings were taken throughout the study. Percent cocks-comb kyllinga and smooth crabgrass were rated on a 0 - 100% scale with 0% representing no control and 100% representing complete control of cockscomb kyllinga or smooth crabgrass. Bermudagrass density was measured on a 0 - 100% scale, with 0% representing no bermudagrass present and 100% representing complete cover. Bermudagrass phytotoxicity was measured on a 0 - 100% scale, with 0% representing no injury to the bermudagrass and 100% representing dead bermudagrass. On August 22, 2010 all treatments containing Certainty resulted in excellent (>90%) cocks-comb kyllinga control. Certainty treatments had no control on smooth crabgrass. The bermudagrass stand density was greater (up to 50%) with treatments containing Certainty compared to the untreated. No phyto was observed with Certainty on either variety of bermudagrass throughout the study. Future research at Clemson University will be to continue to evaluate Certainty safety to other bermudagrass varieties. Continue to evaluate Certainty for weed control efficacy alone and in combination with other herbicides." |
