Abstract: The field experiment was conducted to study the effect of 2.4-D Ethyl Ester 38% EC on rice during the period of 2012 in the subhumid and sub-tropical situation of Regional Research Station, BCKV,West Bengal. The dominant weed floras found in this experiment were Echinochloa colona, Echinochloa crussgalli, Cyperus deformis, Cyperus iria, Ludwigia parviflora, Alternenthera phyloxeroides etc. The pre-emergence application of 2, 4-D EE 38% EC @ 3.40 kg a.i. ha-1 (T5), 2, 4-D EE 38% EC @ 1.70 kg a.i. ha-1 (T4) and 2, 4-D EE 38% EC @ 0.85 kg a.i. ha-1 (T2) resulted in effective weed control, recording the least weed density and weed dry weight. In case of yield, 2, 4-D EE 38% EC 3.40 kg a.i. ha-1 (T5) resulted better yield after hand weeding twice which was at par with other aforesaid treatments.
