Study Design: Randomized Complete Block Design (RCBD) with four replicates. Place and Duration of Study: A series of laboratory and greenhouse experiments was undertaken at the College of Agricultural Studies, Sudan University of Science and Technology (SUST) at Shambat, during the season 2013/2014. Methodology: Striga free or infested soil was placed in plastic pots (9 cm i .d) with perforations at the bottoms. Pots filled with Striga free soil (0 mg) were included as control for comparison. Sorghum cultivar Wad-Ahmed was sown as sole crop or intercropped with cowpea. Chlorsulfuron at 1.3 g active ingredient (a.i)/fed was applied three weeks after sowing. Plant height and Stem diameter were measured in centimetres using a ruler and vernier caliper instrument, respectively, while weight was weighed in gram after drying using a balance.
