“…Amidosulfuron is recommended for use on wheat (winter and spring) and spring barley for the control of broad-leaved weeds. The mechanism of sulfonylureas action and toxicity to higher terrestrial plants is well studied (Duke, 1990;Kudsk, Mathiassen, 2004;Binder et al, 2007), although relatively little is known about the toxic effects of these herbicides on non-target aquatic organisms. Several studies have shown that sulfonylurea herbicides negatively affect growth, physiology and reproduction of non-target aquatic plant (Frankart et al, 2003;Eullaffroy et al, 2007;Fairchild et al, 2007).…”

This study examines effects of sulfonylurea herbicide Sekator OD 375 (amidosulfuron and iodosulfuron) to non-target aquatic plant species common duckweed (Lemna minor L.). The plants were affected by 5-75 µl/l concentrations of herbicide in their growth medium. L. minor had a strong phytotoxicty response to herbicide application (inhibition of growth, biomass, reduced content of photosynthetic pigments and increased content of malondialdehyde). The growth rate of L. minor was inhibited by 54.17%. The dry biomass was by 57.2% lower than in control. Application of herbicide provoked an oxidative stress, the concentrations of MDA was by 83.32% higher than in control.

“…The observed ED 90 doses were plotted on the graph and compared to the ADM isoboles. Points above the isoboles indicate that the joint action of a mixture is lower than predicted by ADM, while points below the isoboles indicate a joint action higher than predicted by ADM (Kudsk & Mathiassen, 2004).…”

“…with the herbicide mixtures originate from up to seven separate experiments, it was necessary to standardize the x-and y-axes so that the ED 90 doses of the herbicides applied separately were always fixed to 1 (Kudsk & Mathiassen, 2004).…”

“…It would be ideal to select herbicide combinations that have synergistic effects on weeds and/or antagonistic effects on crops (Schuster, Al-Khatib, & Dille, 2008). Synergistic herbicidal activity has the potential to reduce cost and the amount of pesticides entering the environment (Kudsk & Mathiassen, 2004;Streibig & Jensen, 2000). For example, common ragweed (Ambrosia artemisiifolia L.) control was improved when dicamba was added to rimsulfuron plus thifensulfuron-methyl (Himmelstein & Durgy, 1996;Kalnay & Glenn, 1997, January).…”

Interaction of binary mixture of the two sulfonylurea herbicides: foramsulfuron or nicosulfuron with 2,4-D + MCPA, was evaluated in greenhouse experiments during 2010 and 2011 applying the additive dose model. Plants of redroot pigweed, common lambsquarters, common purslane and black nightshade were sprayed with seven doses of herbicides alone and in binary fixed-ratio mixtures. In total, 35 binary mixtures were studied in 7 separate experiments at ED 90 response level. Results indicated that mixture of foramsulfuron + 2,4-D + MCPA was synergistic on redroot pigweed compared to additive interaction between nicosulfuron and 2,4-D + MCPA. Mixture of foramsulfuron + 2,4-D + MCPA was slightly antagonistic on common lambsquarters and an additive interaction was observed with both foramsulfuron and nicosulfuron + 2,4-D + MCPA on common purslane. Finally, the mixture of foramsulfuron or nicosulfuron + 2,4-D + MCPA on black nightshade was antagonistic especially in mixtures where the ratio of sulfonylurea herbicides was more than 2,4-D + MCPA. Totally, 2,4-D + MCPA in mixture with sulfonylurea herbicides especially foramsulfuron provided better control of redroot pigweed in comparison with herbicides applied alone and other herbicide mixtures on weeds.Abbreviations: 2,4-D + MCPA: ((2,4-Dichlorophenoxy) acetic acid plus (4-chloro-2-methylphenoxy) acetic acid); ADM: additive dose model; a.i.: active ingredient; ALS: acetolactate synthase; DAT: days after treatment; ED: effective dose; Foramsulfuron: (2-(N-((4,6-dimethoxypyrimidin-

“…Mixing certain chemicals or herbicides with glyphosate has been shown to affect glyphosate efficacy (Kudsk & Mathiassen, 2005;Koger et al, 2007). O 'Sullivan & O'Donovan (1980) observed that a glyphosate in tank mixture with dicamba and 2,4-D reduced the phytotoxicity of glysophate threshold rates on grasses.…”

Control of glyphosate resistant hairy fleabane (Conyza bonariensis) with dicamba and 2,4-D

-Auxyn type herbicides such as dicamba and 2,4-D are alternative herbicides that can be used to control glyphosate-resistant hairy fleabane. With the forthcoming possibility of releasing dicamba-resistant and 2,4-D-resistant crops, use of these growth regulator herbicides will likely be an alternative that can be applied to the control of glyphosate resistant hairy fleabane (Conyza bonariensis). The objective of this research was to model the efficacy, through dose-response curves, of glyphosate, 2,4-D, isolated dicamba and glyphosatedicamba combinations to control a brazilian hairy fleabane population resistant to glyphosate. The greenhouse dose-response studies were conducted as a completely randomized experimental design, and the rates used for dose response curve construction were 0, 120, 240, 480, 720 and 960 g a.i. ha -1 for 2,4-D, dicamba and the dicamba combination, with glyphosate at 540 g a.e. ha . Herbicides were applied when the plants were in a vegetative stage with 10 to 12 leaves and height between 12 and 15 cm. Hairy fleabane had low sensitivity to glyphosate, with poor control even at the 960 g a.e. ha -1 rate. Dicamba and 2,4-D were effective in controlling the studied hairy fleabane. Hairy fleabane responds differently to 2,4-D and dicamba. The combination of glyphosate and dicamba was not antagonistic to hairy fleabane control, and glyphosate may cause an additive effect on the control, despite the population resistance.Keywords: Conyza bonariensis, dose-response, glyphosate-resistant hairy fleabane, weed resistance.RESUMO -Os herbicidas mimetizadores de auxinas como dicamba e 2,4-D são alternativas para o controle de buva resistente ao glyphosate. Com a possível futura liberação comercial de culturas resistentes ao dicamba e 2,4-D, a aplicação destes herbicidas reguladores de crescimento será uma provável alternativa de controle de buva resistente ao glyphosate. O objetivo desta pesquisa foi modelar por meio de curvas de dose-resposta a eficácia do dicamba e 2,4-D isolados e dicamba em associação com glyphosate para controle de uma população de buva resistente. Um estudo de doseresposta em casa de vegetação foi conduzido em delineamento experimental inteiramente casualizado, sendo que as doses utilizadas para a construção das curvas de dose-resposta foram de 0, 120, 240, 480, 720 e 960 g i.a. ha -1 de para o dicamba e o 2,4-D isolados e dicamba associado com 540 g e.a. ha -1 de glyphosate. As doses utilizadas para o glyphosate isolado foram de 0, 180, 360, 540, 720 e 960 g e.a. ha -1. Os tratamentos herbicidas foram aplicados quando as plantas estavam no estádio vegetativo de 10 a 12 folhas e altura entre 12 e 15 cm. A buva apresentou baixa sensibilidade ao glyphosate, pois não foi controlada mesmo na dose de 960 g e.a. ha -1 de glyphosate. O dicamba e o 2,4-D foram eficazes no controle da população de buva estudada. A buva responde de forma diferenciada ao 2,4-D e dicamba e será importante determinar as doses apropriadas de cada herbicida para controle de buva resistente ao glyphos...
