Resumo: The objective of this work was to evaluate the selectivity of different herbicides in the crop of corn and Brachiaria ruziziensis at crop-livestock integration. The experiment was carried out in Nova Xavantina, MT, between January and June of 2008, in soil classified like Rhodic Ferrasol. The trial was installed ar complete randomized block designing , with 11 treatments: lactofen (96 g ha-1); lactofen (192 g ha-1); carfentrazone - ethyl (8 g ha-1); carfentrazone - ethyl (12 g ha-1); flumioxazin (25 g ha-1); flumioxazin (50 g ha-1); lactofen + flumioxazin (96 + 25 g ha-1); lactofen + flumioxazin (192 + 50 g ha-1); nicosulfuron (8 g ha-1); nicosulfuron (40 g ha-1) and a check without herbicide. The treatments were applied at 30 days after the corn emergence. It were evaluated the effects of the treatments in the height, dry biomass and productivity of the corn and, also, in the  dry biomass of the B. ruziziensis. The herbicides flumioxazin, lactofen and carfentrazone-ethyl didn´t present potential to be used in post-emergence in this integrated system, due to low selectivity for corn. Nicosulfuron atrate of 8 a g ha-1 provided corn yeld similar to the check with out herbicides, and a initial small suppression of B. ruziziensis; and, consequently, being the best herbicide to be used for weed management in the no-livestock system.

O experimento foi conduzido no Município de Nova Xavantina – MT, no período de janeiro a junho de 2008, em solo classificado como Latossolo Vermelho distrófico. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições, sendo avaliados 11 tratamentos: lactofen (96 g ha-1); lactofen (192 g ha-1); carfentrazone-ethyl (8 g ha-1); carfentrazone-ethyl (12 g ha-1); flumioxazin (25 g ha-1); flumioxazin (50 g ha-1); lactofen + flumioxazin (96 + 25 g ha-1); lactofen + flumioxazin (192 + 50 g ha-1); nicosulfuron (8 g ha-1); nicosulfuron (40 g ha-1) e testemunha sem herbicida. Os tratamentos foram aplicados aos 30 dias após a emergência da cultura do milho.  Avaliaram-se os efeitos dos tratamentos sobre a altura de plantas, fitomassa seca e produtividade de grãos de milho e, também, sobre a fitomassa seca da B. ruziziensis. Os herbicidas flumioxazin, lactofen e carfentrazone-ethyl não apresentaram potencial para utilização em pós-emergência nesse sistema integrado de cultivo, principalmente por apresentar baixa seletividade à cultura do milho. O nicosulfuron na dose de 8 g ha-1 proporcionou produtividade de grãos de milho equivalente à testemunha sem herbicida, e pequena supressão inicial das plantas de B. ruziziensis, sendo, consequentemente, o mais indicado para o controle de plantas daninhas nesse sistema de integração lavoura-pecuária.UEL2011-08-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1679-0359.2011v32n3p85510.5433/1679-0359.2011v32n3p855Semina: Ciências Agrárias; Vol. 32 No. 3 (2011); 855-864Semina: Ciências Agrárias; v. 32 n. 3 (2011); 855-8641679-03591676-546Xreponame:Semina.
