ABSTRACT

Widespread adoption of herbicide-based weed control in industrialized countries has isolated weed-management practices from other aspects of soybean production. Integrated weed management involves a systems approach that considers contributions of plant breeding, cultural, mechanical and chemical practices in suppressing weed populations and minimizing the impacts of weeds on yield (Deytieux et al., 2012). Integrated weed management changes the focus from eliminating weed interference with soybean growth and yield, to managing the weed seed bank and population fluctuations. Shaner (2014) stated that simple weed-management systems are not sustainable and diversification is the only system that will provide long-term weed management. In addition, cropping systems that utilize integrated weed management improve most environmental indicators (e.g.
