Abstract:

A field experiment was conducted during rainy season in 2019-20 at Navsari Agricultural University, Navsari to identify efficient herbicides and their combinations to manage weeds in non-crop situation. The experiment was laid out in a randomized block design replicated thrice with seven weed management treatments involving herbicides i.e. glyphosate, paraquat, oxyfluorfen, 2,4-D amine salt along with mowing and weedy check. All treatments significantly reduced the weed density and biomass compared to weedy check. Glyphosate 3.0 kg/ha effectively controlled weeds registering negligible weed biomass at 60 days after application (DAA). Glyphosate 2.0 kg/ha alone or in combination with 2,4-D amine salt 2.0 kg/ha (tank-mix) and glyphosate + oxyfluorfen 2.0 kg/ha (ready-mix) were at par in their efficacy to control weeds up to 60 DAA and up to 30 DAA, respectively. Paraquat 4.0 kg/ha and paraquat 2.0 kg/ha + 2,4-D salt 2.0 kg/ha (tank-mix) were found effective up to two weeks only. Thus, glyphosate 2.0 kg/ha alone or in combination with 2,4-D amine salt 2.0 kg/ha (tank-mix) may be used to effectively minimize the weeds biomass and resurgences significantly up to 60 DAA with highest weed control efficiency.
