Abstract: A field experiment was conducted for two years during kharif season of 2014 and 2015 at Directorate of Research building, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, West Bengal to find out the performance of 2, 4-D Dimethylamine 50% SL in non-crop area. The experiment was laid out in Randomized Block Design, comprising of eight treatments. Treatments were as follows: T1 - 2,4-D amine 50% SL (Nufarm) @ 0.75 kg a.i. ha-1, T2 - 2,4-D amine 50% SL (Nufarm) @ 1.25 kg a.i. ha-1, T3 - 2,4-D amine 50% SL (Nufarm) @ 1.50 kg a.i. ha-1, T4 - 2,4-D amine 50% SL (Nufarm) @ 2.00 kg a.i. ha-1, T5 - 2,4-D amine 58% SL(Commercial) @ 1.25 kg a.i. ha-1, T6 - Glyphosate 41% SL @ 1.230 kg a.i. ha-1, T7 - Hand Weeding at 20 DAA & 40 DAA and T8 – Unweeded control treatments and replicated thrice. Cynodon dactylon, Elusine indica, Imperata cylindrica, Ageratum conyzoides, Lantana camera, Parthenium hysterophorous, Cyperus iria and Cyperus rotundus were the pre-dominant weed flora found in the experiment field. The result has shown that among the aforesaid weed control treatments, higher weed control efficiency was recorded in 2,4-D amine 50% SL (Nufarm) @ 2.0 kg a.i. ha-1(T4) (78.07, 88.65 and 91.07 % at 20, 40 and 60 DAA respectively) and 2,4-D amine 50% SL (Nufarm) @ 1.5 kg a.i. ha-1 (T3) (74.29, 85.10 and 88.79 % at 20, 40 and 60 DAA respectively) after the hand weeding twice plot (T7) (81.21, 91.67 and 95.15 % during 20, 40 and 60 DAA respectively).
