A field experiment was conducted at Agricultural Farm, Palli Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan during 2017 and 2018, to study the effect of flumioxazin 50% SL applied as pre-emergence herbicide in summer groundnut (Arachis hypogaea L.). Flumioxazin was applied at 3 different doses at 75 g a.i/ha, 100 g a.i/ha, 125 g a.i/ ha along with standard check of Imazethapyr 10 SL @ 100 g a.i/ha and Pendimethalin 30 % EC @ 750 g a.i/ha and was compared with untreated control, weed free check and hand weeding 20 and 40 days after sowing (DAS). Flumioxazin 50% SL @ 125 g/ ha applied was able to control weed growth during early stages of crop. Flumioxazin 50% SL @ 125 g/ha at 3 DAS registered lower weed density, dry weight, weed index and higher weed control efficiency, better crop growth, highest net return and return per rupee invested. However, yield attributes and yield was highest for weed free plots which was at par to flumioxazin 50% SL @ 125 g/ha.
