The introduction of new cultivation technologies for soybean, corn and cotton contributed to a significant increase in the productivity of these crops. A highlight among these technological advances is the resistance of these crops to glyphosate, which initially provided for better weed control, especially in areas with a great diversity of species. Additionally, from a practical point of view it can also be highlighted that the increased time span for weed control, looking at the possibility of applying glyphosate at various growth stages of RR ® crops. However, the "convenience" provided by the possibility to apply glyphosate post-emergence for crops such as soybeans, corn and cotton, increased consumption of this molecule, resulting in continuous use by producers. The effect resulting from the use was an increased pressure for selection and consequently for the selection of biotypes resistant to this molecule. In addition to this, the presence of volunteer plants of soybean, corn and cotton resistant to glyphosate has been established in management systems, mainly in the succession of soybean-corn and soybean-cotton. This fact brings high control costs and demanded the use of alternatives for the management of these volunteer plants. In this context, the aim of this work to address and present some management strategies to control voluntary RR ® soybean, corn and cotton in cultivation systems in succession of soybean-corn and soy-cotton.
