Evaluation of the herbicides Crosser and Vaquero for weed control in tropical grasslands.

During the 2001rainy season, two experiments were conducted in La Mancha,Veracruz, Mexico, in order to evaluate the effect of theherbicides Crosser (15 g of picloram + 150 g of 2,4-D/L) andVaquero (30 g of triclopyr + 120 g of 2,4-D/L) for controllingLagascea mollis Cav. and Baltimora recta L. in a...

Evaluación de los herbicidas Crosser y Vaquero en el control de malezas herbáceas en pastizales tropicales. Esqueda Esquivel, Valentín Alberto During the 2001rainy season, two experiments were conducted in La Mancha,Veracruz, Mexico, in order to evaluate the effect of theherbicides Crosser (15 g of picloram + 150 g of 2,4-D/L) andVaquero (30 g of triclopyr + 120 g of 2,4-D/L) for controllingLagascea mollis Cav. and Baltimora recta L. in a grassland ofCynodon plectostachyus Vanderyst. In 2002, the experimentswere repeated in La Colonia Independencia, Ver., in agrassland of Digitaria decumbens Stent., infested with Sennaobtusifolia (L.) Irwin & Barneby. Both herbicides, Crosserand Vaquero were applied at 0.75, 1, 1.25, 1.5 and 2 l/100 l ofwater; Full-Mina 4 (480 g of 2,4-D/L) at 1 and 2 l/100 l ofwater, and Esteron 47-M (400 g of 2,4-D/L) at 2 l/100 l ofwater, were also evaluated and a weeded control wasincluded. A Completely Randomized Block Design with fourreplications was used for all the experiments. Weed controland grass toxicity were evaluated at 15, 30 and 60 days aftertreatment application. Crosser controlled B. recta and S.obtusifolia at 0.75 l/100 l of water, whereas to control L.mollis, it was necessary to apply it at 1.5 l/100 l of water.Vaquero also controlled B. recta and S. obtusifolia at 0.75l/100 l of water, but it had no good control of L. mollis. Noneof the herbicide treatments caused any toxicity to the grasses. Durantela estación lluviosa de 2001, se establecieron dos experimentosen La Mancha, mpio. de Actopan, Ver., México, paraevaluar el efecto de los herbicidas Crosser (15 g depicloram + 150 g de 2,4-D/L) y Vaquero (30 g de triclopir +120 g de 2,4-D/L) en el control de la hierba ceniza (Lagasceamollis Cav.) y la flor amarilla (Baltimora recta L.) en un pastizalde zacate Estrella de Africa (Cynodon plectostachyusVanderyst). Los experimentos se repitieron en 2002, en LaColonia Independencia, mpio. de Tres Valles, Ver., en un pastizalde zacate Pangola (Digitaria decumbens Stent.), infestadocon frijolillo [Senna obtusifolia (L.) Irwin & Barneby].Tanto el Crosser como el Vaquero se aplicaron a las dosis de0,75; 1; 1,25; 1,5 y 2 l/100 l de agua y se utilizaron como testigosa Full-Mina 4 (480 g de 2,4-D/L) a 1 y 2 l/100 l de aguay Esterón 47-M (400 g de 2,4-D/L) a 2 l/100 l de agua; un testigosin aplicar también fue incluido. En todos los experimentosse utilizó un diseño experimental de bloques al azar concuatro repeticiones. El control de las malezas y la toxicidad alos pastos se evaluó a los 15, 30 y 60 días después de la aplicación de los tratamientos. El Crosser controló a la flor amarillay al frijolillo desde 0,75 l/100 l de agua, mientras que paracontrolar eficientemente a la hierba ceniza se necesitóaplicarlo a 1,5 l/100 l de agua. El Vaquero también controló ala flor amarilla y al frijolillo a partir de 0,75 l/100 l de agua,pero no tuvo un buen control de la hierba ceniza. Ninguno delos tratamientos ocasionó toxicidad a los pastos. 2013-09-19 2016-05-02T20:54:38Z 2016-05-02T20:54:38Z artículo científico http://revistas.ucr.ac.cr/index.php/agromeso/article/view/11946 10.15517/am.v14i2.11946 http://hdl.handle.net/10669/17654 spa Copyright (c) 2014 Agronomía Mesoamericana application/pdf Universidad de Costa Rica Mesoamerican Journal of Agronomy; Agronomía Mesoamericana: Vol 14, Nº 2; 177-183 Agronomía Mesoamericana; Agronomía Mesoamericana: Vol 14, Nº 2; 177-183 Agronomía Mesoamericana; Agronomía Mesoamericana: Vol 14, Nº 2; 177-183 2215-3608 1021-7444
