Eficácia de herbicidas isolados ou em mistura no controle da planta exótica invasora Urochloa subquadripara

Abstract

O objetivo deste estudo foi avaliar a eficácia dos herbicidas glyphosate, saflufenacil, imazamox, imazapyr e penoxsulam, isolados e em mistura, no controle de Urochloa subquadripara. Para tanto, em casa de vegetação, cinco ponteiros das plantas foram transplantados em caixas de 2,5 litros contento 5 cm de solo, areia grossa lavada e composto orgânico (na proporção 1:1:1). Após 30 dias, foi realizada a aplicação dos herbicidas com pulverizador costal à pressão constante de 25 psi mantida por CO2, com consumo de calda equivalentes a 200 L ha-1. As avaliações foram efetuadas por meio de notas de eficácia aos 3, 7, 15, 21, 30, 45 e 60 dias após a aplicação (DAA). Os herbicidas glyphosate e imazamox, isolados, apresentaram excelente controle (100%) de U. subquadripara, enquanto que, o imazapyr e o penoxsulam (48 g ha-1) apresentaram controle satisfatório com 80 a 85% de eficácia de controle. Os herbicidas glyphosate, imazamox e imazapyr (isolados e em mistura), o saflufenacil + glyphosate (mistura) e o penoxsulam + glyphosate (mistura) podem ser empregados em programas de manejo desta planta aquática invasora.
