Bio-eflicacy of Promising Herbicidal Molecules in Direct Seeded Sprouted Puddled Rice

Field experiment was conducted under All India Coordinated Rice Improvement Project at CSKHPKV Rice Research Station, Malan during 1996 to 2000 to evaluate the bio-efficacy of promising herbicides for weed control in direct seeded sprouted puddled rice. The weed infestation reduced the grain yield of sprouted rice from 24.1 to 43.3% during different years. The mean reduction over five years duration was worked out to be 35.5%. Application of butachlof+safener 50 EC at 1.0 kg ha⁻¹ within three days of sowing remaining statistically at par with anilofos+2, 4-DEE 24+32 EC at 0.40+0.53 kg ha⁻¹ at 10 DAS reduced the accumulation of dry matter by weeds significantly and resulted in higher grain yield. These treatments were as good as two hand weedings at 20 and 40 days after sowing.
