- RENTABILIDAD DEL USO DE HERBICIDA TRONADOR® PARA EL CONTROL DE INVASIONES DE RAMA BLANCA EN PRADERAS DE ZACATE BUFFEL EN SONORA, MEXICO Fernando A. Ibarra Flores Martha H. Martín Rivera Rodolfo Garza Ortega Salomón Moreno Medina Rafael Retes López Estudios Agrarios Brittlebush buffelgrass brush control Sonoran Desert Buffelgrass pastures lose productivity as brittlebush and other species densities increase. Profitability of controll ing high densities of brittlebush in buffelgrass pastures is not well documented. The study was conducted in central Sonora to evaluate the effectiveness of Tronador ® herbicide to control brittlebush and the benefit - cost relation associated with infestatio n reduction. Treatments were: Tronador ® at 0.5 , 1.0, 1.5 and 2.0% in water, Tordon 101 ® 1.0% in water and the untreated check. The herbicide was applied to the foliage in 40 m 2 plots during the summer of 2010 by using a back sprayer. Evaluated variables we re: brush mortality and buffelgrass density, basal cover, height and forage production. A randomized complete block design was used with 6 treatments and 20 replications. All variables were individually analyzed by ANOVA. Financial runs were conducted by u sing a computer program for Project analysis and formulation. Tronador ® herbicide controlled 20, 80, 100 and 100% of brittlebush plants at rates of 0.5, 1.0, 1.5 and 2.0%, and Tordon 101 ® at 1% controlled 100% of the plants. Grass plants were not damaged b y the herbicides. Buffelgrass density, height, basal cover and forage production was increased 35 to 180% with herbicides application. Herbicide treated areas produced annually from 1.5 to 2.16 tons of additional dry forage per hectare. Mean annual income during the projected 14 years was $241.6, $465.9 and $597.6 pesos/ha in a ranch without and with the application of Tronador ® at 1.0 and 1.5% as brush control practices, respectively. A producer with a brittlebush invasion problem which applies these herbi cides for vegetation control may gain additionally from $224.3 to $356.0 pesos/ha, annually. 2016 artículo científico 1405-9282 https://www.redalyc.org/articulo.oa?id=14149188011 es http://www.redalyc.org/revista.oa?id=141 Revista Mexicana de Agronegocios application/pdf Sociedad Mexicana de Administración Agropecuaria A.C.
