| Abstract/Contents: | "The purpose of this study was to evaluate various post emergence herbicides for the control of goosegrass (Eleusine indica). E. indica is a problematic weed of golf course tees, fairways and greens and tends to thrive in compacted poorly drained soils. Resistance has become a concern, particularly to sulfonylurea herbicides. Two separate studies evaluated the effectiveness on juvenile and mature E. indica plants to various post herbicides. Study 1 was initiated June 1, 2010; study 2 was initiated August 2, 2010. Four applications of Acclaim (fenoxaprop) @ 0.015 & 0.029 Lb ai/a, Tenacity (mesotrione) @ 0.047 & 0.062 Lb ai/a, Vantage (sethoxydim) @ 0.063 Lb ai/a, Revolver (foramsulfuron) @ 0.042 Lb ai/a, Illoxan (diclofop) @ 1.05 Lb ai/a, Acclaim + Sencor (Fenoxaprop + Metribuzin) @ 0.015 & 0.25 Lb ai/a, Tenacity + Acclaim (mesotrione + fenoxaprop) @ 0.047 & 0.015 Lb ai/a, Acclaim + Dismiss (fenoxaprop + sulfentrazone) @ 0.015 & 0.25 Lb ai/a and Tenacity + Acclaim + Dismiss + Sencor (mesotrione + fenoxaprop + sulfentrazone + metribuzin) @ 0.047, 0.015, 0.19 and 0.25 Lb ai/a. Sequential applications were applied 14, 28 and 42 days after initial (DAIT). Study 1 was conducted on a non-irrigated fairway comprised of common bermudagrass; study 2 was located on an irrigated fairway consisting of Tifway and common bermudagrass. Applications were made using a CO2 powered sprayer calibrated at 20 GPA. Three treatment replications were applied on 2 X 3 meter plots. Visual ratings were taken to evaluate percent E. indica control and percent bermudagrass phytotoxicity. Ratings were base on 0-100%, 0% indicating no control of phytotoxicity and 100% indicating complete control or phytotoxicity. All applications received a non-ionic surfactant at 0.25 % V/V. ANOVA was evaluated with alpha at 0.05. Illoxan, Revolver, Acclaim + Dismiss, Acclaim + Sencor and Tenacity + Acclaim + Dismiss + Sencor all provided >90% control on Study 1 at the July 20, 2010 rating date. All treatments showed initial phytotoxicity, Acclaim at both rates, Tenacity high rate, Tenacity + Acclaim; and Tenacity + Acclaim + Dismiss + Sencor had >20% phytotoxicity at the June 2, 2010 rating date. Acclaim + Dismiss, Acclaim + Sencor and Tenacity + Acclaim + Dismiss + Sencor remained >30% phytotoxicity as of the June 24, 2010 rating date. Illoxan, Revolver, Acclaim + Dismiss, Acclaim + Sencor and Tenacity + Acclaim + Dismiss + Sencor all provided > 90% control on Study 2 at the September 20, 2010 rating date. Tenacity + Acclaim + Dismiss + Sencor had an initial phytotoxicity rate of iÖ 15% on August 12, 2010; all other treatments were <10%. By September 2, 2010 all treatment phytotoxicity decreased below 10%. Plots will continue to be evaluated for long term effects of the products. Repeat treatments and additional screening of products will be continued for timing and control of goosegrass." |
