Abstract
Field experiments were conducted during 1994–95 and 1995–96 at Pandit Jawaharlal Nehru College of Agriculture and Research Institute, Karaikal, Union Territory of Pondicherry to study the efficacy of pre-emergence herbicides for weed control in lowland transplanted rice. The results revealed that thiobencarb was very effective in controlling weed growth and recorded higher weed control efficiency (82.9 to 92.7%) followed by butachlor (81.1 to 85.0%) and was comparable with two hand weedings at 20 and 40 DAT (83.0 to 87.5%). Among herbicides, thiobencarb @ 1.50 kg ha−1 recorded the maximum yield (4.31 to 4.33 t ha−1) and was on par with weed free treatment (4.43 to 4.51 t ha−1).
