Abstract: Background: Volunteer Acacia mangium represent a major challenge in Eucalyptus plantations due to the large seedbank remaining in the soil. The use of pre-emergent herbicides with residual effects is essential for achieving effective control of these weeds. Objective: To identify effective pre-emergent herbicides, with residual effects for controlling volunteer A. mangium in Eucalyptus plantations. Methods: Completely randomized design (CRD) was used with 4 replications. Trays (50 × 33 cm) were filled with a loamy topsoil from commercial plantations. Each […]

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 […]
