Abstract:
A field experiment was conducted during Rabi seasons of 2012-12 & 2013-14 at Pantnagar to evaluate the effect of ready mixture of metsulfuron methyl and carfentrazone ethyl for the control of broad leaf weeds in wheat (Triticum aestivum) crops. Ready mixture of metsulfuron methyl 10 % + carfentrazone ethyl 40 % DF +0.2 NIS @ 30 g/ha effectively reduced the density& dry matter accumulation of S. nigram, Rumex spinosus, Convolvulus arvensis, Vicia sativa, Anagallis arvensis and Melilotus indica followed by its lower dose @20 g /ha with surfactant and @ 30 g/ha without surfactant which were not effectively controlled by alone application of these herbicides. The ready mix application of metsulfuron methyl 10 % + Carfentrazone ethyl 40 % ) DF +0.2% NIS @25 g/ha had similar level of control to its higher rate of 30 g/ha, but was significantly better than alone application of 2,4-D amine salt 58% SL @ 750 g/ha, metasulfuron and carfentrazone. Maximum grain yield was recorded in ready mix application of metsulfuron methyl 10 % + Carfentrazone ethyl 40 % DF +0.2 NIS @ 30 g/ha which was statistically at par with its lower dose applied @ 25 g/ha with surfactant and without surfactant.
