“…Leys and Slife (1988) reported 58% of applied 14 C metsulfuron was readily absorbed by wild garlic (Allium vineale L.) 144 h after application and 16% of that absorbed material translocated out of the treated leaf. Troxler et al (2003) observed 53% or less of applied 14 C-trifloxysulfuron was absorbed by yellow nutsedge (Cyperus esculentus L.) and purple nutsedge (C. rotundus L.) 96 h after treatment. Unlike turfgrass, the least yellow nutsedge control was observed in Ultima (75 g haG 1 ) followed by Total (40 g LG 1 ) at all application (Table 3).…”

Experiment was conducted in 2013 to evaluate various herbicide treatment regimes for POST yellow nutsedge control. Evaluated herbicides included metsulfuron-methyl+sulfosulfuron, Oxadiazon, Clothedim, Sicloxidim, Nicosulfuron+Rimsulfuron and untreated check. Evaluated treatments did not cause objectionable bermudagrass injury at any time. The highest and the lowest dry weight of turfgrass was achieved in Oxadiazon (211 g mG 2 ) and untreated plots (130 g mG 2 ), respectively. The results of this study indicate that satisfactory control of yellow nutsedge (>90%) obtained by post-emergence application of oxadiazon, clothedim or sicloxidim at the first time and repeat applications will not be required. Further, our results indicate that efforts to enhance yellow nutsedge control with metsulfuron-methyl+sulfosulfuron and nicosulfuron+rimsulfuron timings and repeat applications were inconsistent. These data confirm that the lower bermudagrass phytotoxicity was achieved with the sicloxidim treatment.

“…Imazapic applications were timed to determine whether the physiological characteristics of deeproot sedge during the growing season would respond to herbicide application. Unless deeproot sedge was physiologically ready to translocate foliar-applied herbicide to the roots, only a top-kill would be expected (Brady and Hall 1976;King et al 2014;Sosebee 1984;Troxler et al 2003). Therefore, the most favorable control rates and timing for the herbicide application should be correlated with different stages of plant growth and carbohydrate storage.…”

Response of Deeproot Sedge (Cyperus entrerianus) to Herbicide and Prescribed Fire in Texas Coastal Prairie

Introduced accidentally from South America, deeproot sedge is rapidly expanding in a variety of habitats throughout the southeastern United States. Of particular concern is its rapid expansion, naturalization, and formation of monocultures in Texas coastal prairie, one of the most imperiled temperate ecoregions in North America. The objective of this research was to examine how deeproot sedge responds to prescribed fire, to the herbicide imazapic, and to treatment combinations of both. Combinations of prescribed fire and imazapic treatments and imazapic-only treatments effectively reduced deeproot sedge cover and frequency. However, plots exposed to dormant season fires (with no imazapic) had greater deeproot sedge cover after burn treatments were applied, indicating that coastal prairie management using only dormant season prescribed fire will not work toward reduction or management of this exotic invasive species. Although deeproot sedge cover was often reduced in fire–imazapic treatment combinations, it was still present in treatment plots. Moreover, desirable functional plant groups (i.e., native bunchgrasses) did not respond positively to the fire–imazapic treatments, but in some instances, woody plant coverage increased. Repeated, long-term approaches using integrated and coordinated efforts with multiple treatment options will be necessary to restore community structure to desired compositional levels. Such integrated approaches should be effective in reducing deeproot sedge frequency, cover, and extent to more manageable levels throughout its introduced geographic range.

“…Trifloxysulfuron (experimental code CGA-362622) is a new sulfonylurea herbicide recently registered for POST weed control in cotton (Gossypium hirsutum L.) (Burke and Wilcut 2004;Porterfield et al 2002a;Richardson et al 2003;Troxler et al 2003). Tolerance is based on rapid metabolism in tolerant species (Askew and Wilcut 2002).…”

“…Pyrithiobac and trifloxysulfuron are the only options for POST over-the-top tank mixtures for selective annual broadleaf weed control in transgenic herbicide-resistant cotton cultivars, including glufosinate-, glyphosate-, and bromoxynil-resistant cultivars Richardson et al 2003). Trifloxysulfuron also controls a number of perennial sedge species (McElroy et al 2003(McElroy et al , 2004Troxler et al 2003).…”

Experiments were conducted in weed-free environments to determine corn tolerance to trifloxysulfuron applied PRE or POST, and to determine the potential for trifloxysulfuron applied PRE or POST to cotton to injure corn grown in rotation the following year. Trifloxysulfuron at 3.75, 7.5, or 15 g ai/ha applied PRE or POST resulted in 98% stand reduction of imidazolinone-tolerant (IT) corn and 100% stand reduction in conventional corn. No injury occurred to imidazolinone-resistant (IR) corn. A corn cultivar yield response was observed, with conventional nontreated corn yielding 8,850 kg/ha and greater than nontreated IT corn at 7,900 kg/ha. Nontreated IR corn yielded the least, at 6,400 kg/ha, and these yields were equivalent to trifloxysulfuron-treated IR corn at 6,590 kg/ha. Cotton treated with trifloxysulfuron PRE at any rate was injured less than 8%. Both trifloxysulfuron at 7.5 g/ha POST and pyrithiobac at 70 g ai/ha POST injured cotton 11% early in the season. Neither trifloxysulfuron nor pyrithiobac influenced weed-free cotton lint yields. When grown in rotation, corn was not injured by trifloxysulfuron or pyrithiobac applied the previous year to cotton, and yields were not influenced.
