Resumo: | The aim of this research was to evaluate the efficacy of sequences management systems in late soybean, Glycine max (L.) Merril (Leguminosae-Faboideae), sowing and its influence on the fomesafen application. The experiment was carried out at São João de Ivaí-PR (1998/99), using: (M1) sulfosate + 2,4-D/sulfosate; (M2) sulfosate + 2,4-D/(paraquat+diquat); (M3) sulfosate/(paraquat+diuron); (M4) sulfosate/diquat; (M5) sulfosate/(paraquat+diquat), where M1 was developed 26 days before the sowing (DBS) and during the sowing, and the other systems at 40 DBS and during the sowing. The anticipation of the management systems (40 DBS) allowed a reduction in the use of herbicides and better control of Commelina benghalensis. Fomesafen (125 g i.a./ha), applied in single dose at 19 days after sowing (DAS), made possible sequencial management systems that reached high control level. Its sequence (19 DAS/27 DAS) was satisfactory even when the management was not efficient. M1 was faulty in the C. benghalensis control, allowing the replacement of 2,4-D for sulfosate/diquat or sulfosate/(paraquat+diuron) sequence, both for Ipomoea grandifolia and for C. benghalensis |

Merril (Leguminosae-Faboideae), em condição de estiagem e sua influência sobre o controle de fomesafen, conduziu-se este experimento em São João do Ivaí, Estado do Paraná (1998/99), utilizando-se: (M1) sulfosate + 2,4-D/sulfosate; (M2) sulfosate + 2,4-D/(paraquat+diquat); (M3) sulfosate/(paraquat+diuron); (M4) sulfosate/diquat; (M5) sulfosate/(paraquat+diquat), sendo M1 desenvolvido 26 dias antes da semeadura (DAS) e na semeadura, e os demais sistemas aos 40 DAS e na semeadura. A antecipação do manejo (40 DAS) permitiu redução no uso de herbicidas e melhor controle de Commelina benghalensis. Fomesafen (125 g i.a./ha), aos 19 dias depois da semeadura (DDS), viabilizou sistemas seqüenciais de manejo que atingiram elevados níveis de controle, sendo a sua seqüencial (19 DDS/ 27 DDS) satisfatória, mesmo quando o manejo não foi eficiente. M1 foi deficiente no controle de C. benghalensis, possibilitando substituir 2,4-D por seqüenciais de sulfosate/diquat ou sulfosate/(paraquat+diuron), tanto para Ipomoea grandifolia como para C. benghalensisUniversidade Estadual de Maringá2008-04-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/228410.4025/actasciagron.v24i0.2284Acta Scientiarum.
