Evaluación de herbicidas sistémicos y de contacto en el cultivo de banano (Musa spp.) en la zona de San Juan, cantón Puebloviejo

VII. SUMMARY The present experimental work was carried out in the lands of the Hda. "Kelly" owned by Mr. Roddy Aguirre located on Vía San Juan del Cantón Puebloviejo, Province of Los Ríos, with geographic coordinates of 110597.97 UTM south latitude and 277438.26 UTM west longitude. The material used was the Cavendish established variety, which presented an adequate uniformity in terms of population and agronomic management in the final site. The silver targets were to evaluate the selectivity of the herbicides in the banana crop and to determine the most effective treatment in the control of weeds. Five herbicide products and a mechanical control were used as treatments, such as Arrasador (glyphosate) in doses of 1.5 L / ha; Cerillo (Paraquat) 1,5 L / ha; Galant (Haloxifop Methyl) 1.0 L / ha; Gramocil (Diuron + Paraquat) 2.0 L / ha and Basta (Glufosinate ammonium) 1.5 L / ha. The experimental design called Randomized Complete Blocks (DBCA) with five treatments and three repetitions was used. Comparisons of treatment means were made using the Duncan test at 5% probability. The distance between each plant is 2.40 m sown in the three-bolillo method, where all the tasks and agronomic practices that the crop required for its normal development were carried out, such as trial establishment, irrigation, fertilization, weed control and phytosanitary control. To estimate the effects of the treatments, the toxicity index data were taken from 7 to 42 days, weed control at 14 to 49 days after having applied the herbicides in each treatment, qualifying it by means of the Henderson scale. and Tilton. Based on the results, it was determined that the systemic and contact herbicides used in the cultivation of banana (Musa spp) in the area of San Juan, Puebloviejo canton caused a low level of damage in relation to the toxicity index at 7 days, without report from 14 to 42 days and the best weed control of Caminadora (Rottboellia exaltata); Pata de gallina (Eleusine indica); Guardarocío (Digitaria sanguinalis); Nettle (Urtica dioica) and Ferns (Pteridium aquilinum) from 14 to 49 days was presented by the Galant treatment (Haloxifop Methyl) in a dose of 1.0 L / ha.
