Abstract

An investigation to study the sensitivity of nine wheat varieties, viz. ‘WH 1022’, ‘HD-2687’, ‘C-306’, ‘UP-2338’, ‘PBW-343’, ‘WH-542’, ‘WH-711’, ‘WH-283’ and ‘WH-147’ to  most popular used herbicide combination, i.e. sulfosulfuron + metsulfuron (R.M.) was undertaken at Hisar during Rabi seasons of 2005-06 and 2006-07.  At 15 DAT with recommended dose of herbicide 32 g/ha, the leaves of all wheat varieties except ‘C-306’ showed slight yellowing of leaves which disappeared with passage of time as at 30 days after treatment no yellowing was visible on leaves even at  double to recommended dose (64 g/ha).  In all wheat varieties, the grain yield  with x and 2x  doses was at par with weed-free check but higher than weedy check, indicating no detrimental effect of the herbicide on any variety tested.
