The available herbicides for weed control in rice are of
overseas origin. The country depends on multinational companies for
supply of the herbicides, but usually the companies do not supply the
same brand of herbicides for long time. Thus, continuous evaluation of
the available herbicides in rice is necessary for the benefit of the
farmers of this country. Therefore the objective of this study was to
examine the performance of different pre emergence herbicides in
comparison with manual weeding and a standard herbicide for the
control of weeds in boro/winter rice
