Bispyribac-sodium, Integrated weed management, Transplanted rice 

A field experiment was conducted during Kharif seasons of 2015 to 2017 for three years at Agricultural Research Station, Vadgaon Maval, Pune, Maharashtra to find out the economical methods of weed control in transplanted rice. Post-emergence application of bispyribac-sodium 0.020 kg/ha (PoE) at 21 days after transplanting (DAT) followed by (fb) hand weeding at 45 DAT has effectively managed weeds in transplanted rice and produced the highest net returns (` 70107/ha) with higher B:C ratio (2.3) having lower weed index (2.83) and higher weed control efficiency (87.74 %).
