Resumo: | In Brazil, hairy fleabane stands out among the main weeds of soybean crops, due to its aggressiveness and resistance to glyphosate. Thus, to avoid the selection of resistant populations to the glyphosate herbicide, the use of other herbicides has become critical to the management of this weed. This study aimed to evaluate the control efficiency of glyphosate and saflufenacil herbicides in hairy fleabane plants (Conyza bonariensis), as well as the type of interaction of the combination of those herbicides for controlling glyphosate-resistant hairy fleabane. A randomized blocks design, with four replications, was used. Treatments consisted of glyphosate doses (0 g ha-1; 270 g ha-1; 540 g ha-1; 1,080 g ha-1; 2,160 g ha-1; 4,320 g ha-1; 8,640 g ha-1; 17,280 g ha-1) combined with saflufenacil (0 g ha-1; 0.55 g ha-1; 1.09 g ha-1; 2.18 g ha-1; 4.37 g ha-1; 8.75 g ha-1; 17.5 g ha-1; 35 g ha-1), making six dose-response curves. A synergistic effect was observed between the glyphosate and saflufenacil herbicides for controlling the glyphosate-resistant hairy fleabane, being the mixture considered efficient for the biotype studied. Furthermore, the addition of glyphosate (540 g ha-1) to the saflufenacil herbicide (35 g ha-1) prevented the occurrence of regrowth and the dispersion of new hairy fleabane seeds, what does not occur in plants treated exclusively with saflufenacil. |

Dessa forma, para evitar a seleção de populações resistentes ao herbicida glifosato, o uso de outros herbicidas tornou-se fundamental para o manejo dessa planta daninha. Este estudo objetivou avaliar a eficiência de controle dos herbicidas glifosato e saflufenacil em plantas de buva (Conyza bonariensis), bem como o tipo de interação da combinação desses herbicidas no controle de buva resistente a glifosato. O delineamento utilizado foi o de blocos ao acaso, com quatro repetições. Os tratamentos foram compostos por combinações de doses de glifosato (0 g ha-1; 270 g ha-1; 540 g ha-1; 1.080 g ha-1; 2.160 g ha-1; 4.320 g ha-1; 8.640 g ha-1; 17.280 g ha-1) e saflufenacil (0 g ha-1; 0,55 g ha-1; 1,09 g ha-1; 2,18 g ha-1; 4,37 g ha-1; 8,75 g ha-1; 17,5 g ha-1; 35 g ha-1), formando seis curvas de dose-resposta. Houve efeito sinérgico entre os herbicidas glifosato e saflufenacil para o controle de buva resistente ao glifosato, sendo a mistura considerada eficiente para o biótipo estudado. Além disso, a adição de glifosato (540 g ha-1) ao herbicida saflufenacil (35 g ha-1) preveniu a ocorrência de rebrote e a dispersão de novas sementes de buva, o que não ocorre em plantas tratadas apenas com saflufenacil.Escola de Agronomia - Universidade Federal de Goiás2015-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/33708Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 2, Apr./Jun. 2015; 249-256Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 2, abr./jun. 2015; 249-256Pesquisa Agropecuária Tropical; v. 45, n. 2, abr./jun. 2015; 249-2561983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/33708/18687Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessDalazen, GiliardiKruse, Nelson DiehlMachado, Sérgio Luiz de OliveiraBalbinot, Andrisa2020-07-13T16:20:21Zoai:ojs.revistas.ufg.br:article/33708Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:08.159970Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
