Dry areas have much more problem of weeds as compare to irrigated areas due to aggressive behavior of weeds. Thus competing well with crop and lowering the yield. According to a self-conducted survey in Kohat-Pakistan the major weeds were Carthamus oxyacantha, Avena fatua, Cirsium arvense, Phalaris minor, Convolvulus arvensis, Medicago denticulata, Malcolmia sp., Silybum marianum, Setaria sp., Rumex crispus, Lolium sp., Fumaria indica, Polygonum sp., Vicia sativa and Lathyrus sp. According to farmers surveyed the yield reduction due to these major weeds ranged from 20-50 % in wheat. Keeping in view the losses due to these weeds, an experiment was conducted on the effect of various herbicides for weed control in wheat at Barani Agriculture Research Station, Kohat during the rabi season 2005-2006, using Randomized Complete Block Design with four replications. The experiment comprised of eight treatments, viz; seven herbicides and a weedy check, each treatment consisting of 5 rows each 25 cm apart and 5 m long making treatment size of 5m x 1.5m.
