Resumo: Given the difficulty in controlling dayflower, the aim was to identify what herbicide provides the better control of Commelina benghalensis and the better developmental stage for its application. The plants were grown in pots containing 2 L Bioplant substrate and soil being maintained throughout the trial at a greenhouse. Experimental design was completely randomized with four replications in factorial 8 x 5, so seven herbicides in recommended commercial rates (atrazine, carfentrazone, flumioxazin, glyphosate, MSMA, nicosulfuron and paraquat) and control applied at 5 phenological stages adjusted to BBCH scale. It was observed that the plant phenological stage affects the efficiency of chemical control. Plants at early development stages (BBCH 11 and 12) were more susceptible to herbicides, occurring control in its entirety only with atrazine, carfentrazone, MSMA and paraquat. Despite suffering injuries, C. benghalensis showed tolerance to others treatments. s.

As plantas foram cultivadas em vasos de 2 L contendo substrato Bioplant e solo, sendo mantidas durante todo oexperimento em casa de vegetação. O delineamento experimental utilizado foi inteiramente casualizado com 4 repetições,em esquema fatorial 8 x 5, composto por sete herbicidas em (atrazina, carfentrazone, flumioxazin, glyphosate, MSMA,nicosulfuron, paraquat) e uma testemunha, aplicados em 5 estádios fenológicos ajustados à escala BBCH. Observou-se queo estádio fenológico das plantas tem influência na eficiência do controle químico. Plantas em estádios iniciais dedesenvolvimento (BBCH 11 e 12) mostraram-se mais suscetíveis aos herbicidas, ocorrendo controle em sua totalidadesomente com atrazina, carfentrazone, MSMA e paraquat. Apesar de sofrer fortes injúrias a C. benghalensis apresentoutolerância aos demais tratamentos não ocorrendo a morte das plantas.EDUFU2017-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/3284510.14393/BJ-v33n2-32845Bioscience Journal ; Vol. 33 No. 2 (2017): Mar./Apr.; 268-275Bioscience Journal ; v. 33 n. 2 (2017): Mar./Apr.; 268-2751981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/32845/19967Brazil; ContemporaryCopyright (c) 2017 Valquiria Krolikowski, Fernando Tadeu de Carvalho, Paulo Eduardo Teodorohttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessKrolikowski, ValquiriaCarvalho, Fernando Tadeu deTeodoro, Paulo Eduardo2022-06-21T20:11:27Zoai:ojs.www.seer.ufu.br:article/32845Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-06-21T20:11:27Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false
