Summary: | ABSTRACT Coffee plantations installed at high altitudes and near forested areas have been highly infested with Anredera cordifolia. The objective of this work was to evaluate the effectiveness of different pre- and post-emergence herbicide treatments on A. cordifolia after mechanical mowing. A field experiment was carried out in a coffee plantation with natural infestation of A. cordifolia in a completely randomized design with a split-plot scheme and four replicates, in which the main plot an herbicides application and the subplot was the days after the initial application (DAI). The treatments were as follows: saflufenacil + glyphosate (70 + 960 g a.i. ha-1); chlorimuron + glyphosate (80 + 960 g a.i. ha-1); metsulfuron + glyphosate (6 + 960 g a.i. ha-1); flumioxazin + glyphosate (25 + 960 g a.i. ha-1), and glyphosate (960 g a.i. ha-1); with sequential application of glyphosate (960 g a.i. ha-1); glyphosate + indaziflam (960 + 75 g a.i. ha-1); indaziflam (75 g a.i. ha-1); and a control without herbicide application. Mechanical control, followed by the application of the treatments flumioxazin + glyphosate and metsulfuron + glyphosate in the first application and sequential application of indaziflam, proved to be effective. Control of this weed should be based on the removal of its plant residues from the field to reduce the regrowth and germination of aerial tubers.
RESUMO Plantações de café instaladas em altitudes elevadas e próximas a áreas florestais têm sido altamente infestadas por Anredera cordifolia. O objetivo deste estudo foi avaliar a eficácia de diferentes tratamentos herbicidas pré e pós-emergência sobre A. cordifolia após roçada mecânica. Para tanto, foi conduzido um experimento de campo em uma lavoura de café com infestação natural de A. cordifolia em um delineamento inteiramente casualizado com esquema de parcelas subdivididas com quatro repetições, sendo a parcela principal os tratamentos com aplicação de herbicida e a subparcela os dias após a aplicação inicial (DAI). Os tratamentos foram compostos por: saflufenacil + glifosato (70 + 960 g i. a. ha-1); clorimuron + glifosato (80 + 960 g i. a. ha-1); metsulfuron + glifosato (6 + 960 g i. a. ha-1); flumioxazin + glyphosate (25 + 960 g i. a. ha-1) e glifosato (960 g i. a. ha-1); com uma aplicação sequencial de: glifosato (960 g i. a. ha-1); (6) glifosato + indaziflam (960 g i. a. ha-1); e indaziflam (75 g i. a. ha-1), além de uma testemunha sem aplicação de herbicida.
