| Abstract/Contents: | "SureGuard (flumioxazin 51WDG) is being developed for postemergence winter annual weed control in dormant bermudagrass. However, treated areas also have provided a certain level of preemergence crabgrass control. Therefore, in the winter of 2011-2012 a study was conducted in upstate South Carolina to investigate the efficacy of SureGuard for winter broadleaf weed control and preemergence control of smooth crabgrass (Digitaria ischaemum) in bermudagrass turf. Treatments were applied with a CO2 backpack sprayer calibrated at 40 GPA, using 8004 flat fan spray nozzles. Treatments were replicated three times. Data was analyzed using ANOVA with means separated by LSD (α=0.05). Treatments included: SureGuard at 6 oz/A (0.19 lb.ai/A), SureGuard at 6 oz/A + Manor at 0.33 oz/A (0.012 lb ai/A) and SureGuard at 10 oz/A (0.32 lb ai/A) applied Nov 14, 2011 and Dec 15, 2011 and Jan1 6, Feb 20, and Mar 13 2012. A Monument treatment at 0.45 oz/A (0.021 la ai/A) was applied Dec 15, 2011. All treatments included a non-ionic surfactant at 0.25 % V/V. Visual ratings were taken throughout the study. Percent broadleaf weed control of the various species and smooth crabgrass were rated on a 0 - 100% scale with 0% representing no control and 100% representing complete control In addition percent bermudagrass green-up was measured on a 0 - 100% scale, with 0% representing no bermudagrass green-up and 100% representing complete bermudagrass green-up. NovemberSureGuard applications burned pre-dormant bermudagrass and did not delay green-up the following spring. In addition no SureGuard treatment delayed bermudagrass green-up the following spring. SureGuard applications alone and with metsulfuron provided good efficacy overall on annual broadleaf and grassy weeds. Perennial winter broadleaf efficacy was increased with metsulfuron at the February and March application timings. Smooth Crabgrass control was greater than 80% on June 7, 2012 following the February and March application timings. Future research will continue screening new and experimental herbicides for preemergence crabgrass activity. Research with herbicides used in these studies will continue to evaluate additional combinations and timings." |
