Abstract: The efficacy of various post-emergence herbicides (T1), aminoclopyrald + Floraxypyre (cleanwave150 EC) @ 800 ml /ha, (T2), Fluroxypryre+ MCPA (strain M 50 EC) 750 ml/ha, (T3) Clopyrald+ Floraxypyre+ Tribenuraon (whearstar 66 WPG) @ 500g/ha, (T4), Metsulfuran + tribenuran (Allymax @86 SG) @35 g ha-1, (4). Tribenuran methyl (smbex 75 % WGD) @75 g /ha, against a control were checked against broad leave weeds during the crop season Rabi 2019-2020. The experiment was conducted at two different sites of Dera Ghazi Khan, Pakistan, i.e., Taunsa and Kot Chutta with six treatments and conducted in triplicate . The results revealed that broad leaf weed density significantly decrease by all herbicides as compared to control. However, whearstar (T3) were most effective for controlling all these weeds with maximum mortality 80.57 and 78.21 % and weeds control efficiency 96.9% and 98.1% without being phytotoxic to wheat crop. It also proved most significantly better to reduce the weeds biomass as compared to control. Spike bearing tillers (295.13 and 285) , spike length (16.84 and 15.98 cm), number of grains per spike (50.12 and 47.56) and 1000 grain weight (40.16 and 39.42 mg) on both sites, which ultimately enhanced the yield (5924.16 and 5575.4 kg/ha) as compared to control (3248.3 and 2949.7 kg/ha) on both sites.
