A weed is considered an undesirable plant at a certain place and it causes extensive direct and indirect losses by interfering in crop cultivation, biodiversity loss, and available water reduction in water bodies. Chemical control is a frequently used effective option but it is restricted by environmental degradation, evolution of herbicide resistance in weeds, and health hazards. It requires replacement of present strategy that is based on chemicals to some holistic eco-friendly weed management contrivance, which is not only viable, feasible, and efficient but also sustainable. Therefore, all the economically and ecologically feasible methods should be merged in an overarching way for effective management of weeds. Weeds are constantly evolving and accordingly newer technology should also be evolved. Nanotechnology is playing a crucial role in getting more effective and targeted application of herbicides. As smart delivery system nano-herbicides provide an approach that is environment friendly through lowering inputs of the herbicide, as well as imparting control over release of an active ingredient. Additionally, “Control through utilization strategy” should also be welcomed whereby developing some use of the weed, economic earnings can also be gained along with control of the weed. This chapter will provide information about recent environmentally sustainable approaches used for management of weeds.
