Rice is an important food crop extensively grown in India. Several factors are responsible for reducing the yield of transplant rice. However, weed infestation is the major threat to productivity of transplanted rice. Normally the loss in yield ranges between 16-20%, yet in severe cases the yield losses can be more than 50%, depending upon the species and intensity of weeds. Weed flora under transplanted condition is very much diverse and consists of grasses, sedges and broad-leaved weeds causing yield reduction of rice crop up to 76 %. These weeds could be controlled through manual and chemical methods. Manual method is though very common but cost intensive and chemical weed control is used to overcome weeds infestation which is easy, quick, time saving, cost effective and the most reliable method to control weeds in rice. Herbicides when applied alone is although economical but may have limitation of resistance development, 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 transplanted rice.
