Studies were carried out to evaluate the effect of post- emergence. herbicides and their application methods on weed control in wheat at the Agronomic Research Station, Bahawalpur during 2002-03 and 2003-04. Different herbicides such as, Isoproturon 500 WP @ 2 kg ha-1 (Sprayed, mixed with urea and broadcast, and mixed with sand and broadcast), Isoproturon 500 WP @ 2 kg ha-1 + Buctril-M @ 1 lit ha-1 (Sprayed), puma super 75 EW 1 lit ha-1 (Sprayed), puma super 75 EW @ 1 lit + Buctril-M @ 1 lit ha-1 (Sprayed) were applied as post emergent sprays including weedy control. All herbicides significantly decreased weed population over weedy control. Herbicides applied as sprays proved the best application method. Combination of grassy and broad leaf herbicides was better than their separate application for weed control in wheat. Weed control effectively increased the number of fertile tillers, grains spike-1, 1000-grain weight and wheat grain yield.
