Abstract
Butachlor, thiobencarb, pendimethalin and anilophos were evaluated for weed control in direct- sown, upland rice (Oryza saliva L.) Echinochloa colonum (L.) Link, E. crus-galli (L.) Beauv., Cyperus iria L., Alternanthera sessilis DC. and Commelina communis L. were the major weeds in the experimental field. Population and dry weight of weeds were reduced significantly due to application of herbicides. Butachlor and thiobencarb at 2 kgha resulted in maximum decrease in weed dry weight. Butachlor and thiobencarb (2 kgiha) proved more effective in controlling grass weeds than pendimethalin and anilophos. Herb*icides application resulted in almost similar increase in grain yield.
