Resumo: This study aimed to estimate the effectiveness of weed control in maize (Zea mays L.), under a no-till system, in the Cerrado (Brazilian Savanna) region, by applying pre-emergence herbicides. Two experiments were carried out in Montevidiu, Goiás State, Brazil, during the 2007/2008 crop, in a randomized block design, with four replications. The following treatments were evaluated: atrazine (1,600 g ha-1), atrazine + s-metolachor (1,665 g ha-1 + 1,305 g ha-1), s-metolachor (1,680 g ha-1), atrazine + simazine (250 g ha-1 + 250 g ha-1), and control with and without weeds. It was found out that, 28 days after the treatments application, the herbicides atrazine and s-metolachor were not effective in controlling Cenchrus echinatus and Alternanthera tenella, respectively. The associations between atrazine + s-metolachor and atrazine + simazine have provided significant increases in the Euphorbia heterophilla and Alternanthera tenella control. The presence of weeds had a negative effect on crop yield. KEY-WORDS: Zea mays; atrazine; s-metolachor; simazine; no-tillage.

Foram realizados dois ensaios, no município de Montevidiu (GO), durante a safra 2007/2008, dispostos em delineamento de blocos ao acaso, com quatro repetições. Foram avaliados os seguintes tratamentos: atrazine (1.600 g ha-1), atrazine + s-metolachor (1.665 g ha-1 + 1.305 g ha-1), s-metolachor (1.680 g ha-1), atrazine + simazine (250 g ha-1 + 250 g ha-1) e testemunha com e sem a presença de plantas daninhas. Aos 28 dias após a aplicação dos tratamentos, constatou-se que os herbicidas atrazine e s-metolachor não foram eficientes no controle de Cenchrus echinatus e Alternanthera tenella, respectivamente. As associações entre os herbicidas atrazina + s-metolachor e atrazine + simazine proporcionaram incrementos significativos no controle de Euphorbia heterophilla e Alternanthera tenella. A presença de plantas daninhas influenciou negativamente na produtividade da cultura.
