Resumo: | Weed plants are one of main factors that affect the production of oilseed crops. Their management have been based on chemical control with herbicides, like glyphosate and 2,4-D, due to usefulness and efficiency of applications. However, their use must be managed correctly to mitigate the spray drift. Therefore, this study aimed to evaluate efficacy and spray drift from glyphosate and 2,4-D applications with adjuvants. The drift evaluation of herbicide solutions was conducted in a split-plot arranged in a randomized block design with five replications. Main plots consisted of three herbicide solutions at 150 L ha-1 (glyphosate + 2,4-D, glyphosate + 2,4-D + sodium lauryl ether sulphate, and glyphosate + 2,4-D + fatty acid esters). Sub-plots consisted of five downwind distances (1 to 10 m) from the sprayed area. It was used a fluorecent tracer and drift colectors. The efficacy trial was performed in a randomized block design with four replications in a 3 x 2 factorial scheme, being the same herbicide solutions and two carrier volumes (75 and 150 L ha-1). Droplet spectrum and weed depositon were evaluated and physicochemical properties of the herbicide solutions were characterized. Glyphosate + 2,4-D with or without adjuvants, sprayed using 75 or 150 L ha-1, resulted in similar deposition of tracer on weeds and their control. Those herbicides associated or not with sodium lauryl ether sulphate and fatty acid esters produce similar droplet spectrum and deposition of tracer on drift collectors. |

Seu manejo tem sido baseado no controle químico com herbicidas, como o glifosato e o 2,4-D, devido ao amplo espectro de controle e eficiência das aplicações. Contudo, seu uso deve ser feito corretamente para reduzir a deriva nas pulverizações. Portanto, este estudo teve como objetivo avaliar a eficácia e a deriva da pulverização a partir de aplicações de glifosato e 2,4-D em mistura com adjuvantes. A avaliação de deriva foi realizada em parcelas subdivididas em delineamento de blocos casualizados com cinco repetições. As parcelas principais consistiram de três soluções herbicidas a 150 L ha-1 (glifosato + 2,4-D, glifosato + 2,4-D + lauril éter-sulfato de sódio e glifosato + 2,4-D + ésteres de ácidos graxos). As sub-parcelas consistiram em cinco distâncias a favor do vento (1 a 10 m) da área pulverizada. Utilizou-se um traçador para ser detectado por fluorimetria e coletores de deriva. O ensaio de eficácia foi conduzido em delineamento de blocos casualizados com quatro repetições, em esquema fatorial 3 x 2, sendo as mesmas soluções herbicidas e duas taxas de aplicação (75 e 150 L ha-1). O espectro de gotas e o depósito nas plantas daninhas foram avaliados e as propriedades físico-químicas das soluções herbicidas foram caracterizadas. Glifosato + 2,4-D, com ou sem adjuvantes, pulverizados com 75 ou 150 L ha-1, resultaram em deposição similar do traçador em plantas daninhas, bem como controles equivalentes. Esses herbicidas associados ou não ao lauril éter-sulfato de sódio e aos ésteres de ácidos graxos produziram espectro de gotas e deposição do traçador em coletores de deriva semelhantes.EDUFU2020-04-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4786610.14393/BJ-v36n3a2020-47866Bioscience Journal ; Vol. 36 No. 3 (2020): May/June; 876-885Bioscience Journal ; v. 36 n. 3 (2020): Maio/Junho; 876-8851981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/47866/28630Brazil; ContemporaryCopyright (c) 2020 Guilherme Sousa Alves, João Paulo Arantes Rodrigues da Cunha, Thiago Nunes Landim, Sérgio Macedo Silva, Thales Cassemiro Alves, Caio Silva Goularthttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessAlves, Guilherme SousaCunha, João Paulo Arantes Rodrigues daLandim, Thiago NunesSilva, Sérgio Macedo Alves, Thales CassemiroGoulart, Caio Silva2022-06-20T12:52:32Zoai:ojs.www.seer.ufu.br:article/47866Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-20T12:52:32Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
