Abstract: Ecological weed management differs from traditional weed management in several ways. Ecological weed management strategy is to integrate the options and tools, rather than on specific control practices which are available to make the crops and cropping system unfavorable for weeds and to minimize the impact of any weed that survive. Maintaining appropriate crop rotation with legume and non-legume crops, and growing of cover crop helps to suppress weeds by smothering and allelopathic effects. Growing competitive cultivars, modifying in sowing and planting techniques, changing sowing and planting time, mulching with organic residues, green and brown manuring and the adoption of reduced or zero tillage makes an inappropriate environment for weed seed germinations and their growth. It also stores a higher amount of organic matter by reducing the mineralization rates and subsequently decreases energy consumption and carbon oxide emission. Herbicide use has been a valuable asset for modern agriculture; however, prudent use of chemicals for weed control is essential to fulfilling the goals of sustainable crop production, by reducing detrimental environmental impact, and delaying herbicide resistance development. Further development and testing of alternative weed management practices that can be utilized along with herbicide applications must be pursued in order to make the practice sustainable and successful.
