| Abstract/Contents: | "Goosegrass (Eleusine indica) and Smooth crabgrass (Digitaria ischaemum) are summer annuals distributed throughout the southern United States. Their contrasting textures and unsightly seed heads make them nuisances in turfgrass. The purpose of this research was to investigate the efficacy of various preemergence and postemergence herbicides for Smooth Crabgrass and Goosegrass control. During the spring and summer of 2003 two studies were conducted. Study one, Preemergent control of Goosegrass and Crabgrass, was conducted in Batesburg, SC, and study two, Postemergent control of Goosegrass was conducted in Anderson, SC. The treatments for study one included Pendulum 3.3EC at 2.0 lbs ai/A, Pendulum 3.3EC at 1.5 lbs ai/A, Pendulum 3.8 CS at 3.0 lbs ai/A, Pendulum 3.8 CS at 2.0 lbs ai/A, 1.5 lbs ai/A, Barricade 65 WG at 0.75 lbs ai/A, Barricade 65 WG at 0.38 lbs ai/A, Dimension 40 WP at 0.5 lb ai/A, Dimension 40 WP at 0.38 lbs ai/A, Ronstar 2G at 3.0 lbs ai/A, Ronstar 2G at 2.0 lbs ai/A, Ronstar 2G at 1.0 lb ai/A, Surflan 4 AS at 3.0 lbs ai/A, Surflan 4 AS at 1.5 lbs ai/A, and Scott Goose & Crab 6.56G at 115 lbs/A. Treatments for study two included Revolver 0.19 SC at 28.0 fl oz/A, Monument 75 WG at 0.03 lbs ai/A, Flazasulfuron 25 DG at 3.0 oz product/A, Illoxan 3.0 EC at 1.0 lb ai/A, and MSMA 6.6 + Sencor 75 DF at 2.0 lbs ai/A and 0.25 lb ai/A, respectively. Initial applications for study one occurred on March 9, 2003 with a follow up treatment on May 1, 2003. Initial applications for study 2 occurred on July 7, 2003, with a sequential application on July 24, 2003. All treatments in study two received Lesco NIS (non ionic surfactant) at 0.25% V/V. All of the studies were designed as randomized complete block arrangements with 3 replications each. The treatments were applied using a CO2 backpack sprayer calibrated at 20 GPA, at 31p.s.i., with 8003 flat fan spray tips. For study one, visual Crabgrass and Goosegrass control ratings were recorded 110,144, and 164 DAT. During study two, visual Goosegrass control ratings were recorded 8, 17, 25, 31, and 45 DAT. Ratings for Crabgrass and Goosegrass control in both studies were based on a scale of 0-100% with 0% representing no control and 100% representing complete control. Acceptable control was deemed >90%. For study 1 Pendulum 3.3EC and 3.8CS (2.0 fb 2.0), Pendulum 3.3EC and 3.8CS (1.5 fb 1.5), Barricade 65WG (0.38 fb 0.38), Dimension 40WP (0.5) (0.5 fb 0.5) (0.38 fb 0.38) provided excellent (>90%) crabgrass control 164 DAT. For study one Pendulum 3.3EC and 3.8CS (2.0 fb 2.0) and Dimension 40WP (0.5 fb 0.5) provided excellent (>90%) goosegrass control 164 DAT. For study 2, MSMA + Sencor, Illoxan, and Revolver provided excellent (>90%) control 45 DAT. Monument and Katana had <10% control of goosegrass throughout study. No Bermudagrass injury was observed with any of the treatments. Future research at Clemson University will be to continue to conduct pre and early postemergence grassy weed control studies." |
