Weed infestation is one of the major threats to cereal production in the Nigerian Savanna. Two trials were conducted in 2002 and 2003 to evaluate different types of herbicides for weed control in sorghum. Among the herbicides tested, pretilachlor+dimethametryne at 2.5 kg a.i./ha, cinosulfuron at 0.05 kg a.i./ha and piperophos+cinosulfuron at 1.5 kg a.i./ha performed best as they effectively controlled weeds, increased crop vigour, plant height, reduced crop injury and produced higher grain yield of sorghum.
