“…Peanut (Arachis hypogeae L.) and tobacco (Nicotinia tabacum L.) yields were also not affected by trifloxysulfuron applied to cotton using the same rate structure the previous year Porterfield et al 2005). Results of this study indicated that cotton injury from trifloxysulfuron applied PRE or POST was transient and did not influence cotton lint yield.…”

Experiments were conducted from 1998 to 2000 at Rocky Mount, NC, in weed-free environments to determine soybean tolerance to preplant (PP) applications of trifloxysulfuron and the potential for trifloxysulfuron applied preemergence (PRE) and postemergence (POST) to cotton to injure soybean grown in rotation the following year. Trifloxysulfuron at 3.75 and 7.5 g ai/ha applied PP 2 wk before seeding injured conventional soybean less than 5%, whereas no injury was observed when seeding was delayed 4 or 6 wk after PP treatment. No injury to sulfonylurea-resistant soybean (SR) was observed for any treatment. Soybean yields were not influenced by trifloxysulfuron treatment. Cotton injury was 7% or less with trifloxysulfuron applied PRE or POST at 3.75 and 7.5 g/ha. Trifloxysulfuron at 15 g/ha PRE or POST injured cotton a maximum of 14 to 18%. Trifloxysulfuron did not reduce cotton lint yields regardless of method or rate of application. Both conventional and SR soybean were not injured nor were yields influenced by trifloxysulfuron applied PRE or POST the previous year to cotton.

“…(2005), examining efficacy of different herbicide treatments than in this study at Halkidona, northern Greece, determined higher cotton (lint) yields in herbicide treated cotton than in the untreated. Similarly, Porterfield et al . (2005) reported greater yields in pre‐transplant herbicide treated tobacco compared to the non‐treated check.…”

Field experiments were conducted in northern Greece in 2003 and 2004 to evaluate effects of tillage regimes (moldboard plowing, chisel plowing, and rotary tilling), cropping sequences (continuous cotton, cotton-sugar beet rotation, and continuous tobacco) and herbicide treatments with inter-row hand hoeing on weed population densities.Total weed densities were not affected by tillage treatment except that of barnyardgrass (Echinochloa crus-galli), which increased only in moldboard plowing treated plots during 2003. Redroot pigweed (Amaranthus retroflexus) and black nightshade (Solanum nigrum) densities were reduced in continuous cotton, while purple nutsedge (Cyperus rotundus), E. crus-galli, S. nigrum, and johnsongrass (Sorghum halepense) densities were reduced in tobacco. A. retroflexus and S. nigrum were effectively controlled by all herbicide treatments with inter-row hand hoeing, whereas E. crus-galli was effectively reduced by herbicides applied to cotton and tobacco. S. halepense density reduction was a result of herbicide applied to tobacco with inter-row hand hoeing.Yield of all crops was higher under moldboard plowing and herbicide treatments. Pre-sowing and pre-emergence herbicide treatments in cotton and pre-transplant in tobacco integrated with inter-row cultivation resulted in efficient control of annual weed species and good crop yields. These observations are of practical relevance to crop selection by farmers in order to maintain weed populations at economically acceptable densities through the integration of various planting dates, sustainable herbicide use and inter-row cultivation; tools of great importance in integrated weed management systems.

“…Trifloxysulfuron rates were 0.0036 and 0.053 kg/ha. Similarly, Porterfield et al (2005) observed tobacco tolerance to POST and PD treatments of trifloxysulfuron at 0.0038 and 0.0075 kg/ha. Plant sensitivity to ALS-inhibiting herbicides is usually attributed to enhanced metabolism in the tolerant plant species relative to the susceptible species, although differential uptake can contribute to this tolerance (Askew and Wilcut 2002;Brown and Neighbors 1987;Troxler et al 2003;Wilcut et al 1989).…”

“…After 3 wk of growth, plants were treated with trifloxysufluron at 6 g ai/ha plus 0.25% v/v nonionic surfactant. 3 Herbicide rate corresponds to rates within the rate range used by Bailey et al (2004) and Porterfield et al (2005). Herbicide applications were made with a moving belt spray chamber calibrated to deliver 190 L/ ha at 146 kPa.…”

Research was conducted to evaluate absorption, translocation, and metabolism of foliar-applied trifloxysulfuron in flue-cured tobacco. The majority of 14C-trifloxysulfuron was absorbed by 4 h, with an accumulation in the plant of 43% of the radioactivity after 72 h. Translocation of radioactivity did not significantly differ between harvest timings of 4 to 72 h after treatment. Not more than 4% of applied 14C-trifloxysulfuron moved out of the treated leaves of tobacco, whereas less than 1.9% accumulated in any one part. Tobacco metabolized 14C-trifloxysulfuron rapidly, with 60.9% of the absorbed herbicide remaining in the parent herbicide form 4 h after treatment, whereas only 12.1% remained after 72 h. These data suggest that limited absorption and translocation, as well as rapid metabolism, are the basis for tobacco tolerance to foliar-applied trifloxysulfuron and illustrate the potential safe and effective use of trifloxysulfuron in tobacco for POST weed control.
