“…Sulfentrazone provides effective weed control of many grass and broadleaf weeds (Krausz et al 1998;Vidrine et al 1996) including Florida beggarweed and nutsedge species (Hancock 1999;Wehtje et al 1997). Sulfentrazone is currently registered for use in soybean (Dirks et al 2000;Vidrine et al 1996), tobacco (Nicotiana tabacum L.) (Gooden and Murdock 1999;Hancock 1998;Walker et al 1998), several turfgrass species (Blum et al 2000;Bunnell et al 2001), sugarcane (Saccharum officinarum L.) (Viator et al 2002), and several vegetable crops (Haar et al 2002;Manning and Fennimore 2001). The status of sulfentrazone (0.084 to 0.28 kg ai/ha) registra-tion in peanut is being considered currently (Vencill et al 2002).…”

Field studies were conducted in 2000 and 2001 in Plains, GA, to determine peanut and weed response to the residual herbicides sulfentrazone, imazapic, diclosulam, and flumioxazin. Herbicide treatments included sulfentrazone applied preemergence (PRE) or preplant incorporated (PPI) at 112, 168, 224, and 280 g ai/ha, imazapic postemergence (POST) at 71 g ai/ha, diclosulam PPI at 26 g ai/ha, and flumioxazin PRE at 88 g ai/ha. Peanut exhibited early-season injury from all herbicide treatments, ranging from 0 to 10% for sulfentrazone PPI or PRE, 10% for imazapic, 3 to 23% for flumioxazin, and 1 to 7% for diclosulam. Yields were similar for sulfentrazone PPI- or PRE-treated and flumioxazin-, imazapic-, and diclosulam-treated peanut. Yellow nutsedge control was 83% or greater with all rates of sulfentrazone PRE or PPI, 83 and 90% with diclosulam, and 96 and 99% with imazapic, respectively. Flumioxazin did not control yellow nutsedge or wild poinsettia. Tall morningglory control was 82% or greater with imazapic, diclosulam, flumioxazin, and sulfentrazone PPI or PRE at 168 g/ha or higher. Florida beggarweed control was 88% or greater with diclosulam, flumioxazin, and sulfentrazone PRE at 224 and 280 g/ha. Overall, peanut tolerance to sulfentrazone at 112 to 280 g/ha PPI and PRE was high and yield was equivalent to the currently registered peanut residual herbicides.

“…Oxadiazon is a protoporphyrinogen oxidase inhibitor that effectively controls annual weeds, such as Asian spikesedge (Kyllinga squamulata Thonn. ex Vahl), annual bluegrass (Poa annua L.), large crabgrass (Digitaria sanguinalis L.), and goosegrass (Eleusine indica L.) in established bermudagrass fairways (Brecke et al 2010;Bunnell et al 2001;Callahan and High 1990). Oxadiazon can be applied during bermudagrass establishment from sprigs and has been shown not to reduce rooting of Tifgreen, Tifdwarf, or Tifway bermudagrass (Bingham and Hall 1985;Brecke et al 2010;Fagerness et al 2002;Johnson 1980Johnson , 1985McCullough et al 2007).…”

Preemergence Herbicides Influence Sprig Establishment of ‘TifEagle’ Bermudagrass

et al. 2012

The presence of weeds during bermudagrass putting green establishment can reduce growth and turf quality. Three field experiments were conducted in Georgia to investigate efficacy of dimethenamid,S-metolachlor, and oxadiazon on the establishment of ‘TifEagle’ bermudagrass from sprigs. Dimethenamid at 0.85 and 1.7 kg ai ha−1,S-metolachlor at 1.1 and 2.2 kg ai ha−1, and oxadiazon at 1.1, 2.2, and 4.4 kg ai ha−1did not reduce bermudagrass cover from the untreated after 8 wk.S-metolachlor at 4.4 kg ha−1was the only treatment that reduced sprig cover from the untreated after 12 wk. AllS-metolachlor and oxadiazon treatments provided excellent (≥ 90%) green kyllinga control by 8 wk after treatment (WAT) while dimethenamid at 0.85, 1.7, and 3.4 kg ha−1provided 78, 85, and 92% control, respectively. Dimethenamid treatments provided poor control (< 70%) of spotted spurge but fair control (70 to 79%) was achieved fromS-metolachlor at 4.4 kg ha−1and oxadiazon at 2.2 and 4.4 kg ha−1by 8 WAT. Overall, low to middle rates of the herbicides tested appear to temporarily inhibit TifEagle bermudagrass sprig establishment but high rates of dimethenamid andS-metolachlor may reduce cover from the untreated.

“…On 'Tifgreen' bermudagrass, oxadiazon gave 100% control of Digitaria sanguinalis (L.) in 3 consecutive years (Callahan and High, 1990). Single and sequential applications of oxadiazon effectively control Kyllinga squamulata, annual bluegrass, and goosegrass (Eleusine indica L.) in higher-mowed bermudagrass turf (Johnson, 1976a;Bunnell et al, 2001;Toler et al, 2003). Oxadiazon is also used in combination with bensulide for preemergence weed control in bermudagrass turf.…”

Preemergence herbicides are applied to prevent summer annual weed infestations in turf, but safety to dwarf-type bermudagrass golf greens has not been determined for many of these materials. Field experiments tested ‘TifEagle’ bermudagrass response to bensulide at 11.2 kg·ha−1 (a.i.), dithiopyr at 0.56 kg·ha−1 (a.i.), napropamide at 2.2 kg·ha−1 (a.i.), oxadiazon at 2.2 kg·ha−1 (a.i.), oxadiazon plus bensulide at 1.7 + 6.7 kg·ha−1 (a.i.), and pendimethalin at 1.7 kg·ha−1 (a.i.). All herbicides reduced root mass from the nontreated, but only losses incited by oxadiazon plus bensulide were acceptable (less than 20%). Dithiopyr, napropamide, and pendimethalin delayed spring greenup in 2003 and 2004, whereas oxadiazon plus bensulide delayed spring greenup in 2004. In greenhouse experiments, ‘TifEagle’ bermudagrass root mass was reduced 19% to 37%, 30% to 33%, 4% to 26%, 28% to 37%, and 24% to 30% from various rates of bensulide, dithiopyr, napropamide, and pendimethalin, respectively. Oxadiazon and oxadiaxon plus bensulide reduced root mass by only 2% to 15% and 15% to 22%, respectively. In another experiment, oxadiazon plus bensulide at 1.7 + 6.7 kg·ha−1 did not injure shoots or roots of ‘Champion’, ‘FloraDwarf’, ‘MiniVerde’, ‘Tifdwarf’, or ‘TifEagle’ bermudagrass. Overall, dwarf-type bermudagrass golf greens do not appear to tolerate mitotic inhibitor preemergence herbicides, whereas oxadiazon or oxadiazon plus bensulide caused minimal injury.
