Resumo: | The control of Conyza spp. can be conducted at different times in the soybean crop. This study aimed to evaluate the efficiency of controlling Conyza spp. by positioning herbicides at different times and their selectivity in the soybean crop. The experiment was conducted under field conditions in a randomized block design with four replications. A first application of 2.4-D + glyphosate (975 + 1500 g of active ingredient [a.i.] ha-1) was conducted, followed by the following treatments: glufosinate (500 g i.a. ha-1), diquat (400 g a.i. ha-1), and saflufenacil + glyphosate (50 + 1500 g a.i. ha-1 ) and a third application of the pre-emergents flumioxazin + imazethapyr (60 + 127 g i. a. ha-1), sulfentrazone + diuron (210 + 420 g a.i. ha-1), diclosulam (35 g a.i. ha-1), and s-metolaclhor (1440 g a.i. ha-1), in addition to the control treatment. High percentages of control were obtained with saflufenacil + glyphosate and diquat. Glufosinate provided satisfactory control seven days after the treatment (DAT) application, with regrowth throughout the evaluations, except when diclosulam was applied. The pre-emergent herbicides reduced the emergence of Conyza spp. resulting in 0.25 plants m-2 when flumioxazin + imazethapyr was applied at 28 DAT. Regardless of the treatment, the soybean crop had no significant phytotoxicity. The management of Conyza spp. with the positioning of herbicides at different times proved to be more efficient when the sequential use of diquat and/or saflufenacil + glyphosate and flumioxazin + imazethapyr in pre-emergence was carried out. |

O objetivo desse trabalho foi avaliar a eficiência no controle de Conyza spp. através do posicionamento de herbicidas em diferentes momentos, e sua seletividade na cultura da soja. O experimento foi realizado em campo no delineamento de blocos ao acaso, com quatro repetições. Foi realizada uma primeira aplicação de 2,4-D + glyphosate (975 + 1500 g de ingrediente ativo [i.a.] ha-1) e na sequencial os tratamentos: glufosinate (500 g i.a. ha-1), diquat (400 g i.a. ha-1) e saflufenacil + glyphosate (50 + 1500 g i.a. ha-1 ) e uma terceira aplicação dos pré-emergentes flumioxazin + imazethapyr (60 + 127 g i.a. ha-1), sulfentrazone + diuron (210 + 420 g i.a. ha-1), diclosulam (35 g i.a. ha-1) e s-metolaclhor (1440 g i.a. ha-1), além das testemunhas. Altas porcentagens de controle foram obtidas com saflufenacil + glyphosate ou diquat. O glufosinate, proporcionou controle satisfatório 7 dias após a aplicação dos tratamentos (DAT), com rebrotas ao longo das avaliações, exceto quando ocorreu aplicação do diclosulam. Os herbicidas pré-emergentes diminuíram a emergência de Conyza spp. resultando em 0,25 plantas m-2, na aplicação de flumioxazin + imazethapyr aos 28 DAT. Não houve fitotoxicidade significativa na cultura da soja independente do tratamento. O manejo de Conyza spp. através do posicionamento de herbicidas em diferentes momentos, mostrou-se mais eficiente quando realizado a sequencial de diquat e/ou saflufenacil + glyphosate e flumioxazin + imazethapyr em pré-emergência.Universidade Federal Rural do Semi-Árido2023-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/1060310.1590/1983-21252023v36n402rcREVISTA CAATINGA; Vol. 36 No. 4 (2023); 748-756Revista Caatinga; v. 36 n. 4 (2023); 748-7561983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/10603/11316Copyright (c) 2023 Revista Caatingainfo:eu-repo/semantics/openAccessSilva, Paulo Vinicius daBarros, Daniela MariaDomingos, Edson RochaMonquero, Patrícia AndreaDias, Roque de CarvalhoVendruscolo, Marlon Alexsandro2023-09-28T13:12:06Zoai:ojs.periodicos.ufersa.edu.br:article/10603Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:57.646959Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
