“…Moran et al (2011) have reported that the combination of Na-bentazon to saflufenacil has reduced noticeable injuries and increased the height, dry matter of plants and the yield of maize, compared to the isolated application of saflufenacil.…”

“…In this regard, some herbicides are used as safeners of other herbicides, providing reduction of injuries to crops and increasing the application time (Moran et al, 2011). As examples, there are benoxacor for metolachlor in maize (Foy & Witt, 1991;Viger et al, 1991), cyprosulfamide for isoxaflutole in maize (Nelson & Penner, 2006), Na-bentazon for saflufenacil in maize (Moran et al, 2011) and tritosulfuron in wheat (Weinberg et al, 2007).…”

“…The protective effect of Na-bentazon was attributed to reduced absorption and translocation of the herbicide by plants (Weinberg et al, 2007;Moran et al, 2011). Interference in the foliar uptake was attributed to antagonism of ATPase by bentazon (Couderchet & Retzlaff, 1991).…”

-The objective of this study was to assess the selectivity herbicide saflufenacil for two sweet sorghum hybrids, when sprayed in preemergence and postemergence, besides the use of Na-bentazon as a 'safener' for saflufenacil. Three experiments were conducted, in pots, maintained in an ambient condition (second and third experiments) and in a greenhouse (first experiment). In each experiment a completely randomized distribution was used, with four replicates. In the first (2 x 6 factorial) two hybrids of sweet sorghum (CVSW 80007 and CVSW 80147) and six dosages (0; 35; 52.5; 70; 87.5 and 105 g ha ) of saflufenacil were studied, applied in preemergence of the plants. In the second (2 x 5 factorial) the same hybrids of sweet sorghum sprayed in postemergence with saflufenacil (0; 35; 52.5; 70 and 87.5 g h -1 ) were assessed. In the third (4 x 5 factorial) the association of Na-bentazon (0; 240; 480 and 720 g ha ) was studied, when sprayed in postemergence on the sweet sorghum plants (CVSW 80007). Hybrid CVSW 80147 was more tolerant to saflufenacil than hybrid CVSW 800007, in preemergence or postemergence applications. The variables that best assessed the sensibility of the sweet sorghum to saflufenacil were number of emerged plants, for preemergence applications, and dry matter of stem for postemergence. Na-bentazon showed promise for use as 'safener' in postemergence applications of saflufenacil in sweet sorghum for dosages up to 70 g ha 0; 35; 52,5; 70; 87,5; e 105 g ha -1 ) de saflufenacil, aplicado em pré-emergência das plantas. No segundo (fatorial 2 x 5), foram estudados os mesmos híbridos de sorgo sacarino pulverizados em pós-emergência com saflufenacil (0; 35; 52,5; 70; e 87,5 g ha -1 ). No terceiro (fatorial 4 x 5), foi avaliada a associação do 240, ) ao saflufenacil (0; 35; 52,5; 70; e 87,5 g ha -1 ), quando pulverizados em pós-emergência das plantas de sorgo sacarino (CVSW 80007 . RESUMO -Objetivou-se estudar a seletividade do herbicida saflufenacil para dois híbridos de sorgo sacarino, quando pulverizado em pré e pós-emergência, além do uso de Na-bentazon como safener para saflufenacil. Três experimentos foram desenvolvidos, em vasos, mantidos em condição ambiente (segundo e terceiro experimento) e no interior de casa de vegetação (primeiro experimento). Em cada experimento, o delineamento experimental foi o inteiramente casualizado com quatro repetições. No primeiro (fatorial 2 x 6), foram avaliados dois híbridos de sorgo sacarino (CVSW 80007 e CVSW 80147) e seis dosagens (

“…In other studies, dry bean have shown crop injury with cloransulam-methyl and halosulfuron-methyl applied post-emergence (POST) in some market classes of dry bean (Soltani et al 2010). Bentazon has been shown to reduce crop injury in dry bean and other crops when tankmixed with injurious herbicides such as tritosulfuron, thifensulfuron, saflufenacil and imazethapyr (Bauer et al 1995;Lycan and Hart 1999;Weinberg et al 2007;Moran et al 2011). In another study, halosulfuron caused up to 67% injury when applied POST at 35 g a.i.…”

Soltani, N., Nurse, R. E. and Sikkema, P. H. 2013. Weed management in white beans with postemergence herbicide tankmixes. Can. J. Plant Sci. 93: 669–674. Weed control efficacy of cloransulam-methyl, halosulfuron, bentazon, fomesafen and their tankmixes applied post-emergence (POST) for weed management in white bean was evaluated in field studies conducted in four Ontario locations during 2008–2011. Cloransulam-methyl, halosulfuron, bentazon, fomesafen, bentazon plus fomesafen, cloransulam-methyl plus bentazon, cloransulam-methyl plus fomesafen, cloransulam-methyl plus bentazon plus fomesafen, halosulfuron plus bentazon, halosulfuron plus fomesafen, and halosulfuron plus bentazon plus fomesafen caused white bean injury ranging from 1 to 18%. Control for AMARE, AMBEL and CHEAL ranged from 47 to 92%, 66 to 98% and 36 to 91%, respectively, among herbicide treatments. Similar results were observed for weed density and biomass of AMARE, AMBEL, and CHEAL. Cloransulam-methyl, halosulfuron, and cloransulam-methyl plus fomesafen reduced the yield of white bean by 34, 21, and 17%, respectively, compared with the weed-free control. However, bentazon, fomesafen, bentazon plus fomesafen, cloransulam-methyl plus bentazon, cloransulam-methyl plus bentazon plus fomesafen, halosulfuron plus bentazon, halosulfuron plus fomesafen, and halosulfuron plus bentazon plus fomesafen had no adverse effect on yield of white bean. Based on these results, tankmixes of cloransulam-methyl and halosulfuron with bentazon and fomesafen can reduce crop injury and provide control of broadleaf weeds in white bean.

Bentazon, applied as a tankmix, has been shown to have the potential for reducing the injury from some POST herbicides. Field experiments were conducted in 2008 and 2009 at Exeter, ON and in 2009 at Ridgetown, ON to determine if the addition of bentazon reduces the injury from cloransulam-methyl or halosulfuron-methyl applied POST in black, cranberry, kidney and white beans. Bentazon added to cloransulam-methyl reduced the level of injury 0 to 6% at 17.5 g·ai·ha–1 and 0 to 9% at 35 g·ai·ha–1 in dry bean. Bentazon added to halosulfuron-methyl reduced the level of injury as much as 4% at 35 g·ai·ha–1 and 6% at the 70 g·ai·ha–1. Bentazon added to cloransulam-methyl increased plant height as much as 3 cm. The addition of bentazon to halosulfuron-methyl had no effect on the height of various market classes of dry bean. Bentazon added to cloran-sulam-methyl generally has no effect on seed moisture content in black and white bean but decreased seed moisture content of cranberry and kidney bean as much as 4%. The addition of bentazon to halosulfuron-methyl caused no effect on seed moisture content of dry bean. Cloransulam-methyl caused a 7% to 18% reduction in dry bean yield compared to halosulfuron-methyl and 12% to 21% reduction in yield compared to bentazon. Bentazon added to cloransulam-methyl increased dry bean yield by 0.16 and 0.31 t·ha–1 at Exeter (2009) and Ridgetown (2009) respectively. The addition of bentazon to halosulfuron-methyl had no effect on dry bean yield
