Rice is an important staple food crop of India. Several factors are responsible for reducing the yield of Kharif rice. However, weed infestation is the major threat to productivity of Kharif rice. Weeds by the virtue of their high adaptability and faster growth dominate the crop habitat and reduce the yield potential of the crop. These weeds could be controlled through various methods. Manual method is though very common but cost intensive. Herbicides when applied alone are although economical but may have limitation of resistance development and shift in weed flora etc. Therefore, presently there is a need to use high efficacy herbicides in combination coupled with broad spectrum nature to control the complex weed flora in Kharif rice.
