A field experiment was carried out with twelve weed control treatments during the winter season of 2012-13 and 2013-14 on a silty clay loam soil to evolve an effective herbicide combination to control the complex weed flora in garden pea. Phalaris minor (28.8%), Alopecurus myosuroides (21.3%), Avena ludoviciana (15.8%), Lolium temulentum (12.1%) and Vicia sativa (16.7%) were found major weeds in experimental area. Pendimethalin 1000 g/ha supplemented with one HW at 45 DAS being statically at par to the application of pendimethalin 1000 g/ha (pre) fb imazethapyr + imazamox 60 g/ha (post) significantly reduced the density of major weeds. In general, the efficacy of the formulated mixtures whether as double knock or as a sole application was found better than the sole application of herbicides. Pendimethalin 1000 g/ha fb one HW and pendimethalin 1000 g/ha fb imazethapyr + imazamox 60 g/ha being statistically alike with weed free resulted in significantly higher number of nodules, green pod yield and straw yield.
