Abstract: Background: Beardgrass (Schizachyrium microstachyum) is a perennial weed with high rusticity and prolificacy. Control failures and the significant increase in its migration from native fields to cultivated areas indicate the need for new management strategies. Objective: The goal was to evaluate the control efficacy and emergence of S. microstachyum in response to the application of pre-emergent herbicides, considering the interaction with and without straw cover. Methods: The experiment was conducted in a greenhouse and repeated over two seasons. The […]

Background Marandu grass can be an alternative forage in the crop-livestock integration system (CLI), although its burndown is slower than ruziziensis grass, and it is necessary to speed it up so that the sowing of early soybean cultivars occurs at the recommended time. Objective Estimate times and doses of glyphosate and ammonium- glufosinate in sequential burndown of marandu grass with and without cutting for a shorter period of burndown. Methods Four experiments in randomized blocks and three replications were carried […]
