HALOXIFOPE-P-METÍLICO PARA CONTROLE DE BRACHIARIA DECUMBENS NA CULTURA DO EUCALIPTO Henrico Luiz Bizão de Assis Anne Elise Cesarin Mariluce Pascoina Nepomuceno Tiago Pereira Salgado Pedro Luis da Costa Aguiar Alves Agrociencias Controle Competição Urochloa decumbens Eucalyptus urograndis A cultura do eucalipto expandiu-se para a região Centro-Oeste do País,áreas onde antes havia pastagens, sobretudo deBrachiaria decumbens(capim-braquiária),passando essa a se constituir a principal planta daninha. O presente trabalho objetivouavaliar a eficácia haloxifope-p-metílico no controle deB. decumbensinfestando mudas deeucalipto (Eucalyptus urograndis) e sua seletividade para a cultura. Para tanto, montou-se um experimento com três situações: eucalipto plantado isoladamente, eucalipto emconvivência com a espécieB. decumbenseB. decumbensplantada isoladamente. Aos 67dias após o plantio das mudas foi feita a aplicação do haloxifope-p-metílico nas doses de0; 48 e 96 g.i.a.ha-1. A aplicação de haloxifope-p-metílico, na maior dose (96 g.i.a.ha-1),proporcionou um bom controle da planta daninha. O herbicida, nas doses testadas, foiseletivo à cultura do eucalipto e a convivência entre eucalipto eB. decumbensresultou eminterferência negativa para ambas as espécies. 2015 artículo científico 0104-7760 https://www.redalyc.org/articulo.oa?id=74444232005 pt http://www.redalyc.org/revista.oa?id=744 CERNE application/pdf Universidade Federal de Lavras CERNE (Brasil) Num.4 Vol.21
