Resumo: | The selection of bioindicator species for ethoxysulfuron can enable the study of the behavior of this herbicide in the soil through the bioassay technique. Thus, this study aimed to select species with potential for use as bioindicators of the presence of this herbicide in the soil. A completely randomized design with four replications was used in which four plant species (sorghum, cucumber, beet and tomato) were cultivated in soil submitted to the application of six doses of ethoxysulfuron (0, 18.75, 37.5, 75, 112.5 and 150 g ha-1). Phytotoxicity, plant height (PH), shoot dry matter (SDM), root dry matter (RDM) and total dry matter (TDM) were evaluated. Different levels of tolerance of the species to ethoxysulfuron were observed: the increased doses of ethoxysulfuron reduced PH, SDM, RDM and TDM, as well as increased phytotoxicity for cucumber, beet and tomato. Sorghum showed low sensitivity to the herbicide. The highest doses inhibited the growth in height and the accumulation of dry matter of cucumber. Beet behaved as an extremely sensitive species, with a reduction of 100% in PH and dry matter in the second lowest dose (37.5 g ha-1). Among the evaluated species, the cucumber has greater potential for use as bioindicator in studies with ethoxysulfuron. |

Utilizou-se o delineamento inteiramente casualizado, com quatro repetições, em que quatro espécies vegetais (sorgo, pepino, beterraba e tomate) foram cultivadas em solo submetido à aplicação de seis doses de ethoxysulfuron (0; 18,75; 37,5; 75; 112,5 e 150 g ha-1). Avaliou-se a fitointoxicação, altura de plantas (ALT) e matéria seca da parte aérea (MSPA), da raiz (MSR) e total (MST). Foram observados diferentes níveis de tolerância das espécies ao herbicida: o aumento das doses de ethoxysulfuron reduziu as variáveis ALT, MSPA, MSR e MST e aumentou a fitointoxicação para pepino, beterraba e tomate. O sorgo apresentou baixa sensibilidade ao herbicida. As maiores doses avaliadas inibiram o crescimento em altura e o acúmulo de matéria seca do pepino. A beterraba se comportou como espécie extremamente sensível, com redução de 100% em ALT e matéria seca a partir da segunda menor dose (37,5 g ha-1). Entre as espécies avaliadas, o pepino apresenta maior potencial para uso como bioindicadora em estudos com ethoxysulfuron.Universidade Federal Rural da Amazônia/UFRA2018-10-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2613Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 61 (2018): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 61 (2018): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
