Broad leaf weeds, Wheat, Metsulfuron methyl, 2,4-D EE

Field investigations were carried out during three consecutive rabi seasons (2000-01 to 2002-03) at Bikaner (Rajasthan) with a view to find out the broad spectrum post emergence herbicide against broad leaf weeds in wheat (Triticum aestivum). Results revealed all cultural and post emergence herbicidal treatments effectively reduced the dry weight of weeds by 33.6-91.3% as compared to weedy check. The highest values of tillers/plant, length of ear, test weight and grain yield of wheat (2530 kg/ha) obtained with B: C 3.1 under post emergence application of metsulfuron-methyl at 0.004 kg/ha. The grain yield recorded with this treatment was at par with that recorded with post emergence 2,4-D EE at 0.5 kg/ha .
