| Abstract/Contents: | "The purpose of this study was to evaluate various pre-emergence and post-emergence herbicides for the control of Doveweed (Murdannia nudiflora). M. nudiflora is a problematic weed of golf course roughs, fairways and tees. Little research is present evaluating the efficacy of various herbicides on M. nudiflora. Two separate studies evaluated the efficacy of various herbicides on M. nudiflora for pre-emergence and post-emergence control. Study 1 included two timings of pre-emergence herbicide application with the early timing initiated on March 17, 2010 and the late timing initiated on April 14, 2010. Pre-emergent treatments included Tower (Dimethenamid) 21 & 32 oz/ac, Tower fb Tower 21 oz/ac, Tower fb Tower 32 oz/ac, Pendulum (Pendimethalin) 3lb ai/ac fb Tower 32 oz/ac, Pendulum + Tower 3 lb ai/ac & 32 oz/ac, Gallery (Isoxaben) 1 lb ai/ac, Barricade (Prodiamine) 1 lb ai/ac, Pennant Magnum (S-metolachlor) 4 pt/ac, Ronstar Flo (Oxadiazon) 3 lb ai/ac, Simazine (Simazine) 2 lb ai/ac, Spectacle (Indaziflam) 24 g ai/ac and Broadstar (Flumioxazin) 150 lb/ac. Sequential applicatios were applied 8 WAIT. Study 2 evaluated post-emergence herbicides for doveweed control. Applications were made on July 14, 2010. Treatments included Surge (Sulfentrazone, 2,4-D, Mecoprop-p and Dicamba) 3.25 pt/ac, Speedzone (Carfentrazone-ethyl, 2,4-D, Mecoprop-p and Dicamba) 4 pt/ac, Onetime (Quinclorac, Mecoprop-p and Dicamba) 64 oz/ac, Dicamba (Dicamba) 1 pt/ac, Buctril (Bromoxynil and MCPA) 2 pt/ac, Revolver (Formasulfuron) 26 oz/ac, MSMA (Monosodium acid methanearsonate) 2 lb ai/ac, Celsius (Iodosulfuron-methyl-sodium, Dicamba) 105 g/ac, Surge + Tower (Dimethenamid) 0.81 lb ai/ac & 21 oz/ac, Speedzone + Tower 0.5 lb ai/ac and 21 oz/ac, Onetime + Tower 1.25 lb ai/ac & 21 oz/ac, Dicamba + Tower 0.5 lb ai/ac & 21 oz/ac, Buctril + Tower 1 lb ai/ac & 21 oz/ac, Revolver + Tower 0.04 lb ai/ac & 21 oz/ac and MSMA + Tower 2 lb ai/ac and 21 oz/ac. Study 1 and Study 2 were conducted on irrigated golf course rough comprise of Tifway-419 bermudagrass. Applications were made using a CO2 powered sprayer calibrated at 20 GPA. Three treatment replications were applied on 1.5 X 2 meter plots. Visual ratings were taken to evaluate percent M. nudiflora control. Ratings were based on 0-100%, 0% indicating no control and 100% indicating complete control. All applications received a non-ionic surfactant at 0.25% V/V. ANOVA was evaluated with alpha at 0.05. Greater than 60% control was not seen in any pre-emergence treatments in the March timing of study 1 at any rating date. Ronstar Flo and Tower 21 oz/ac fb Tower 21 oz/ac 8 WAIT showed 50% control 119 DAI (July 14, 2010). Greater than 70% control was not seen in any pre-emergence treatment in the April timing of study 1 at any rating date. Tower 21 oz/ac fb Tower 21 oz/ac 8 WAIT, Tower 32 oz/ac fb Tower 32 oz/ac 8 WAIT, Specticle, Boradstar showed >60% control 92 DAI (July 14, 2010). No significant control was seen September 9, 2010, regardless of application timing. Celsius demonstrated >80% control 29 DAI in study 2. No other treatments showed >60% control at any rating date. Additional herbicides will continue to be evaluated for pre and post emergence doveweed control along with alternate application timings to target doveweeds late germination period." |
