e0“Preemergence application of pretilachlor 0.80 kg/ha and butachlor 1.50 kg/ha at seven days after sowing (DAS) remaining statistically at par with post-halod hand weeding was significantly better than all post-halod herbicide treatments (pretilachlor 0.80 kg/ha, butachlor 1.50 kg/ha and 2, 4–0 (ethyl ester) 0.50 kg/ha alone and in combination with pretilachlor 0.40 kg/ha and butachlor 0.75 kg/ha), with regard to uptake of N, P and K by weeds and rice.”
