Conventionally wheat is grown in well prepared land followed by 3-4 full tillage which carry out degradation of natural resources and contribute to an increased cost of cultivation. Adopting strip tillage (single shallow pass) technology in wheat reduces the expenditure on field preparation and saves more than 30-60% fuel and time as well as advances the sowing time compared to conventional tillage practices (Mahal et al., 2009). But, early season weed control is critical for successful strip-till production (Mitchell et al., 2009). Moreover, weed can cause grain yield reduction in wheat by 50-80% (Montazeri et al., 2005). Both grass and broadleaved weeds infest wheat, but heavy broadleaved weed infestation causes significant wheat yield reduction (Zand et al., 2007), deteriorates the quality of wheat resulting low market value and also causes obstruction in harvesting. Broadleaved weed control in wheat could be easy and convenient if appropriate post-emergence herbicide can apply. Therefore, the study had taken to evaluate the efficacy of available post-emergence herbicides to control broadleaved weeds and to select a number of efficient post-emergence herbicides under strip tillage system
