Studies on the Effect of Weed Management Practices on Weed Control in Drum Seeded Wet Rice

Field experiments were conducted to study the effect of weed management practices on the control of weeds in drum seeded wet rice. The weed management practices with and without pre-sowing application of glyphosate alongwith a pre-emergence application of pretilachlor (with safener) or an early post-emergence application of butanil followed by one or two manual weedings were compared with farmer's method of three manual weedings and unweeded check. Among the weed management practices pre-sowing application of glyphosate+pre-emergence application of pretilachlor (with safener) followed by two manual weedings effectively controlled a wide spectrum of weeds, and recorded a maximum grain yield of 5872 kg ha⁻¹.
