Abstract
Field studies conducted during kharif 1997 and 1998 at experimental farm of CSK Himachal Pradesh Krishi Vishvavidyalaya, Palampur revealed that while cyhalofopbutyl 90 g ha−1 (20 DAS) was superior in decreasing the dry weight of Echinochloa crusgalli, 2,4-DEE 1.0 kg ha−1 (20 DAS) was superior to control sedges and broadleaf weed species when applied alone. Tank mix application of 2,4-DEE with cyhalofopbutyl reduced the efficiency of the latter to reduce dry matter of E. crusgalli and of total weeds indicating their antagonistic effect. Although sequential application of cyhalofopbutyl 75 g ha−1 (20 DAS) fb. butachlor 1.0 kg+2,4-DEE 1.0 kg ha−1 (30 PAS) being at par with cyhalofopbutyl at 90 g ha−1 (20 DAS) fb. 2,4-DEE 1.0 kg ha−1 (30 DAS) was effective to reduce the dry matter of all weeds except Cyperus iria, but cyhalofopbutyl at 90 g ha−1 (20 DAS) when applied alone resulted in significantly highest grain yield of rice by causing significant reduction in dry matter of E. crusgalli, the major and most competitive weed.
