| Abstract/Contents: | "Smooth crabgrass (Digitaria ischaemum), goosegrass (Eleusine indica), and yellow nutsedge (Cyperus esculentus) are common weeds of both warm and cool-season turf. F9001 is a new herbicide mixture of sulfentrazone (206.3 g ai/l) + dithiopyr (273.5 g ai/l). Research trials were conducted in 2010 evaluating the efficacy of sprayable (SC) and granular (G) formulations of F9001 for control of yellow nutsedge, smooth crabgrass, and goosegrass. Trial #1 was conducted on a mature stand of tall fescue (Festuca arundinacea) infested with smooth crabgrass at the East Tennessee Research and Education Center in Knoxville, TN. Plots (1.5 by 3 m) were maintained as a golf course rough and arranged in a randomized complete block design with three replications. Treatments included both SC and G formulations of F9001 (493 g ai/ha, 706 g ai/ha and 908 g ai/ha), dithiopyr (426 g ai/ha), and sulfentrazone (281 g ai/ha) + prodiamine (562 g ai/ha). All treatments were applied at a preemergence (PRE) smooth crabgrass timing on 24 March. Trials #2 and #3 conducted on a mature stand of zoysiagrass (Zoysia japonica) infested with goosegrass and yellow nutsedge at the East Tennessee Research and Education Center in Knoxville, TN. Plots (1.5 by 3 m) were maintained as a golf course rough and arranged in a randomized complete block design with three replications. Treatments included both SC and G formulations of F9001 (493 g ai/ha, 706 g ai/ha and 908 g ai/ha) and dithiopyr (426 g ai/ha). Applications were made at PRE, 1-4 leaf (1-4LF), and 1-2 tiller (1-2TL) stages of goosegrass growth on 6 May, 4 June, and 16 June, respectively. Sprayable treatments in all trials were applied with a CO2 powered boom sprayer calibrated to deliver 280.5 L/ha utilizing four, flat-fan, 8002 nozzles at 124 kPa, configured to provide a 1.5-m spray swath. Granular treatments were applied by hand. Weed control and turf injury were visually evaluated in all trials utilizing a 0 (no weed control or turf injury) to 100 % (complete weed control or turf injury) scale at 30, 60, 90, 120, and 146 days after initial treatment (DAIT). At no time during these studies was tall fescue or zoyisagrass injury observed. In Trial #1, all treatments controlled smooth crabgrass iĆ7% on all rating dates before 90 DAIT. All treatments controlled smooth crabgrass iĆ85% after 90 DAIT through the end of the study. In Trials #2 and #3, all treatments applied PRE controlled goosegrass iĆ7% from 30 DAIT through the end of the study. Applied PRE, F9001 SC (706 and 908 g ai/ha) controlled yellow nutsedde id'Y85% at 90 and 120 DAIT as well. Applied 1-4LF, F9001SC and G (706 and 908 g ai/ha) controlled goosegrass iĆ78% at 60 DAIT through the end of the study. Comparitevely, F9001SC and G (493 g ai/ha) and dithiopyr applied at 1-4LF controlled goosegrass iĆn all rating dates. All F9001 treatments applied 1-4LF controlled yellow nutsedge iĆ93% 60 DAIT through the end of the study. At 1-2TL all treatments controlled goosegrass iĆ22% and yellow nutsedge iĆ95% at 60 DAIT through the end of the study. All dithiopyr treatments controlled yellow nutsedge 0% on all rating dates. These data suggest applications of F9001 can provide PRE control of smooth crabgrass, PRE and early postemergence (POST) control of goosegrass, and PRE and POST control of yellow nutsedge." |
