Última CHLOROPHYLL FLUORESCENCE IN Brachiaria decumbens AND Brachiaria ruziziensis SUBMITTED TO HERBICIDES Planta Daninha SILVEIRA,R.R.; SANTOS,M.V.; FERREIRA,E.A.; SANTOS,J.B.; SILVA,L.D.. ABSTRACT Different doses of herbicides can promote a differentiated physiological response in grasses of the same genus. This study has been proposed in order to evaluate physiological responses of B. ruziziensis and B. decumbens submitted to glyphosate and fluazifop-p-butyl. Treatments were distributed in a 2 x 6 factorial design with five repetitions, being two grasses: B. decumbens cv. Basilisk and B. ruziziensis with six doses of herbicides: 0.00; 0.25; 0.50; 1.00; 1.5 and 2.00 times the commercial dose recommended by manufacturers. At 7, 15, 21, and 30 days after herbicide application (DAA) chlorophyll luminous energy uptake efficiency was evaluated. Plants subjected to glyphosate at 7 days after application (DAA) showed minimum fluorescence of 270...

Ano: 2017 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-83582017000100248 HERBICIDE SELECTIVITY TO SIGNAL GRASS AND CONGO GRASS Planta Daninha ANÉSIO,A.H.C.; SANTOS,M.V.; SILVEIRA,R.R.; FERREIRA,E.A.; BRAZ,T.G.S.; TUFFI SANTOS,L.D.; SANTOS,J.B.. ABSTRACT This study was conducted in order to evaluate the selectivity of signal grass and congo grass, submitted to post-emergence herbicide application. The experiment was conducted under greenhouse conditions, in Diamantina, Minas Gerais state, and it was arranged in a randomized block design, with five replications. Treatments were set in factor scheme (8 x 2) + 2. Eight herbicides (nicosulfuron; clomazone; glyphosate; fluazifop-p-butyl + fomesafen; lactofen; fomesafen; fluazifop-p-butyl and mesotrione) were applied in doses recommended by the manufacturer on two fodder species: Brachiaria decumbens cv. Basilisk (signal grass) and Brachiaria ruziziensis (congo grass); in addition, there were two control samples without herbicide application, for a...
