| Abstract/Contents: | "Studies were conducted from 2008 through 2012 at the University of Florida, West Florida Research and Education Center near Jay, FL to determine the effectiveness of selected herbicides for annual grass control in warm-season turfgrass. Annual bluegrass (Poa annua L.) was controlled with a single fall preemergence application of indaziflam. When evaluated 100 days after application, 35 and 55 g a.i. indaziflam/ha provided 95% control. At 160 days after treatment control with 35 g/ha had decreased to 80% while 55 g/ha still controlled annual bluegrass at 95%. The standard treatments of prodiamine or foramsulfuron controlled annual bluegrass lest than 75%. Both methiozolin and amicarbazone applied postemergence controlled annual bluegrass 85 to 90% for up to 150 days after application. A single application of indaziflam preemergence at 50 to 60 g a.i./ha provided long-term control (85 to 90% for 170 days) of southern crabgrass (Digitaria ciliaris (Retz.) Koel.). Dithiopyr controlled southern crabgrass 95 to 100% when applied preemergence and 85 to 95% when applied to southern crabgrass at the 1 to 4 leaf stage. However control with dithiopyr declined to 60% 120 days after treatment when applied to crabgrass at the 1 to 2 tiller stage and to 45% when applied at the 3 to 5 tiller stage. Quinclorac and mesotrione were both effective in controlling southern crabgrass (85% control 85 days after treatment) when applied postemergence. Indaziflam applied preemergence provided 85 to 95 % goosegrass (Eleusine indica (L.) Gaertn.) control 110 days after application. A single application of indaziflam at 53 g/ha in March 2011controlled goosegrass at 95% the following July and at 60% when evaluated July 2012. Dimethenamid provided 95% control of goosegrass 120 days after application when applied as a sequential treatment 60 days after a preemergence application of pendimethalin. This combination controlled goosegrass better than a sequential of pendimethalin preemergence followed by a second application of pendimethalin." |
