This study has aimed to verify the influence of the droplets size categories and application volumes on burn down Urochloa ruziziensis and Conyza sp. Therefore, two trials were conducted in a randomized block design with four replications in a 2×4 split plot arrangement. The plots consisted in droplets size categories (very fine droplets and ultra coarse droplets) and the subplots consisted in four application volumes (50, 100, 150 and 200 L ha-1). For desiccation, glyphosate herbicide was used at 0.975 […]
