Cultural and Chemical Methods of Weed Control in Transplanted Rice

Abstract

There was no significant different between the preplant application of paraquat at 0.8 kg a.i./ha and puddling six times. Hand weeding and working rotary weeder recorded the maximum yield when compared to the herbicides rogue, butachlor propanil and 2,4-D, which were in turn better than unweeded check. The combination of post emergence application of propanil and paraquat was also not effective. But propanil combined with thorough land preparation and paraquat combined with hand weeding recorded the same yield as good land preparation and cultural methods of weed control.
