Abstract

Oryza sativa, cereal crop grown worldwide which feeds 60% of world. DSR, feasible and resource conserving technique of rice cultivation is gaining popularity, but due to weed infestation, crop experience a yield loss from 15%-100%. Various journals were assessed and books were consulted with the objective of compiling the various weeds of DSR and their management strategies in a comprehensive single document. Weed can be manage by different methods but integration of all methods is the best and eco-friendly compared to chemical one. Biotechnological method for development of herbicide resistance varieties, biological methods are new and are best alternative options. Different pre and post emergence herbicides could be applied to kill or suppress in short period with recommended doses and stage of crop. No single method is perfect for killing all the weeds, integrating different strategies having different modes of action can reduce the weed density and resistance to herbicides.
