Abstract: Background: To successfully control A. hybridus, it is necessary to adopt integrated management programs, such as the use of desiccants associated with cultural practices, with pre and/or post-emergent herbicides, varying action mechanisms due to resistance to ALS and EPSPs inhibitors that the species has. Objective: To evaluate the herbicide effectiveness applied in pre and/or post-emergence for the chemical management of A. hybridus. Methods: Experiments were carried out in a greenhouse, in the first one it was applied pre-emergent herbicides; […]
