Controle e susceptibilidade de capim-braquiária e capim-ruziziensis ao glyphosate e fluazifop-p-butil

Abstract: Este estudo teve como objetivo avaliar o controle e susceptibilidade de capim-braquiária e capim-ruziziensis em crescimento inicial submetidos a diferentes doses dos herbicidas glyphosate e fluazifop-p-butil. Os tratamentos foram arranjados no esquema fatorial 2 × 6, com cinco repetições, sendo duas gramíneas: Brachiaria decumbens cv. Basilisk (capim-braquiária) e B. ruziziensis (capim-ruziziensis), e seis doses dos herbicidas: 0,00; 0,25; 0,50; 1,00; 1,5 e 2,00 vezes a dose comercial indicada pelos fabricante… Show more

“…Brightenti et al [ 63 ] observed that glyphosate application had a control efficiency of 85% at 25 DAA for Urochloa decumbens . Silveira et al [ 64 ] found 100% control of Urochloa decumbens at 15 DAA, and the authors explained that in the early stages of development of these grasses, control is facilitated because the plant tissues have a greater capacity to transport herbicide molecules and have a lower capacity to recover from the injuries caused. In the aforementioned study, pesticide application was carried out when the plants had three to four formed tillers (new grass shoots) and an average height of 0.30 to 0.35 m.…”
