Sorghum (Sorghum bicolor L.) crop provides nutritious forage for domestic animals during fodder scarcity months in Pakistan. Poor weed management is one of the important factors that reduces its forage yield. Bio-enhancer may improve the efficacy of pre-and post-emergence herbicides. Weed control efficacy of bromoxynil + MCPA + metribuzin alone and with the addition of bio-enhancer was investigated in a randomized complete block design (RCBD) with four replications. Treatments included weedy check, bromoxynil + MCPA + metribuzin @ 1000, 1125 and 1250 ml ha^-1 with and without bio-enhancer (Alkyl Ether Sulphate applied at the rate of 400 ml ha^-1) thus making a total of seven treatments per replication. All the weedicide treatments with or without adjuvant significantly decreased the weed flora. The lower density, dry weight of different weeds and the highest values of sorghum plant height (218.27 cm), stem diameter (3.25 cm),number of leaves plant^-1 (15.06) and forage yield (104 t ha^-1) were recorded in treatment where bromoxynil + MCPA + metribuzin@ 1000 ml ha^-1 + bio-enhancer @ 400 ml ha^-1was sprayed. On the basis of these results, it is suggested that under arid to semi-arid agro-ecological conditions farmers can harvest 78.15% more forage sorghum yield at reduced rate of 1000 ml ha^-1 of bromoxynil + MCPA + metribuzin with adjuvant.
