Abstract: The efficacy of some potent herbicides in conjunction with halod (interculture in standing rice crop with desi plough) for control of weeds in direct seeded puddled rice was studied during1994 and 1995 at Palampur. The major weeds found were : Echinochloa sp., Ammania baccifera, Scirpus sp., Cyperus iria and C. difformis. Pre-emergence application of pretilachlor (0.80 kglha) and butachlor (1.50 kglha before the imposition of halod being statistically at par with post- halod hand weedings as and when required were significantly better than all the post-halod herbicide treatments with regard to weed control, yield attributes and yield. However, all the post-halod herbicides decreased the population and dry matter accumulation by weeds significantly in comparison to only halod. Amongst the post-haiod herbicide treatments, tank mixed combinations of butachlor 0.75 kglha and pretilachlor 0.40 kg/ha with 2, 4-DEE 0.50 kglha being statistically at par with farmers practice of halod followed by hand weeding, produced perceptible increase in grain yield over halod only.
