Resumo
Objetivou-se avaliar a seletividade de herbicidas aplicados na grama Batatais (Paspalum notatum) e na grama São Carlos (Axonopus compressus) em campo. O delineamento experimental utilizado foi o de blocos casualizados com quatro repetições. As gramas foram cortadas a 3 cm de altura e, em seguida, realizaram-se as aplicações dos herbicidas. Os tratamentos utilizados foram: testemunha (sem aplicação), fluazifop-p-butil (125 g ha-1), sethoxydim+óleo mineral (276 g ha-1 + 0,5% v v-1 de Assist), bispyribac-sodium (25 g ha-1), chlorimuron-ethyl (15 g ha-1), ethoxysulfuron (150 g ha-1), halosulfuron (112,5 g ha-1), iodosulfuron-methyl (10 g ha-1), metsulfuron-methyl (2,4 g ha-1), nicosulfuron (125 g ha-1), pyrithiobac-sodium (140 g ha-1), trifloxysulfuron-sodium (22,5 g ha-1), 2,4-D (720 g ha-1), quinclorac (375 g ha-1), atrazina (1.250 g ha-1), bentazon (600 g ha-1), linuron (1.350 g ha-1), fomesafen (187,5 g ha-1), lactofen (120 g ha-1), oxadiazon (600 g ha-1) e oxyfluorfen (720 g ha-1). Os herbicidas que apresentaram potencial de seletividade para o gramado de P. notatum foram o chlorimuron-ethyl, ethoxysulfuron, pyrithiobac-sodium, 2,4-D, bentazon e fomesafen; já para o gramado de A. compressus foram o chlorimuron-ethyl, ethoxysulfuron, halosulfuron, iodosulfuron-methyl, metsulfuron-methyl, pyrithiobac-sodium, 2,4-D, quinclorac, atrazina, bentazon, além do fomesafen.
The objective of this study was to evaluate the selectivity of herbicides applied on Bahiagrass (Paspalum notatum) and Broadleaf Carpetgrass (Axonopus compressus) turfgrasses under field conditions. The experiment was arranged in a randomized block design, with four replications. The turfgrasses were cut to the height of 3 cm, followed by herbicide application.. The treatments were: control, fluazifop-p-butyl (125 g ha-1), sethoxydim+mineral oil (276 g ha-1 + 0.5% v v-1 of Assist), bispyribac-sodium (25 g ha-1), chlorimuron-ethyl (15 g ha-1), ethoxysulfuron (150 g ha-1), halosulfuron (112.5 g ha-1), iodosulfuron-methyl (10 g ha-1), metsulfuron-methyl (2,4 g ha-1), nicosulfuron (125 g ha-1), pyrithiobac-sodium (140 g ha-1), trifloxysulfuron-sodium (22.5 g ha-1), 2,4-D (720 g ha-1), quinclorac (375 g ha-1), atrazine (1,250 g ha-1), bentazon (600 g ha-1), linuron (1,350 g ha-1), fomesafen (187.5 g ha-1), lactofen (120 g ha-1), oxadiazon (600 g ha-1) and oxyfluorfen (720 g ha-1). The herbicides with selectivity potential for P. notatum were chlorimuron-ethyl, ethoxysulfuron, pyrithiobac-sodium, 2.4-D, bentazon and fomesafem and those with selectivity potential for A. compressus were chlorimuron-ethyl, ethoxysulfuron, halosulfuron, iodosulfuron-methyl, metsulfuron-methyl, pyrithiobac-sodium, 2.4-D, quinclorac, atrazine and bentazon, besides fomesafen.
