The experiment was conducted during rabi season of 2014-15 and 2015-16 at Regional Research Station of New Alluvial Zone (NAZ), Gayeshpur of West Bengal to find out the bio-efficacy and phytotoxicity of 2, 4-D dimethyl amine 50% SL for weed control in potato and its effect on succeeding crop greengram. Elusine indica, Cynodon dactylon, Cyperus rotundus, Cyperus iria, Anagallis arvensis, Chenopodium album and Fumaria parviflora were the dominant weeds. The post emergence application of 2, 4-D amine 50% SL 4.0 kg a.i. ha-1 has resulted in effective weed control, recording the least weed density and weed dry weight and there by higher weed control efficiency after hand weeding twice treatment plot. Among the herbicide, maximum grain yield was recorded under 2, 4-D amine 50% SL 3.0 kg a.i. ha-1 (23.00 t ha-1). The herbicide 2, 4-D amine 50% SL tested at different doses was found safe to potato and did not cause any residual toxicity to succeeding crop greengram.
