Abstract
To evaluate the performance of acetachlor, atrazine and 2, 4-D Na alone or as tank mixture, an experiment was conducted during kharif seasons of 1999 and 2000 at Research Farm of CCS Haryana Agricultural University, Hisar, India. Among 17 weed control treatments, atrazine at 0.50 kg/ha applied as pre-emergence (PE) or 10 days after sowing (DAS), acetachlor+atrazine at 0.750+0.375 kg/ha at 10 DAS proved highly effective (>90%) against Trianthema portulacastrum and Echinochloa colona in pearl millet and consequently yielded similar to mechanical weeded (20 and 35 DAS) and weed free plots during both the years. Acetachlor alone or in combination with atrazine or 2, 4-D Na as pre-emergence (PE) resulted in severe phytotoxicity to pearl millet (92–98% in 1999 and 50–54% in 2000); however, it also provided effective control of both the weeds (85–98%). Acetachlor applied as post-emergence (10 and 15 DAS) was ineffective against weeds in this crop. Post-emergence application of 2, 4-D Na at 0.50 kg/ha resulted in marginal growth suppression of T. portulacastrum only.
