Intercropping is widely practised in Nigeria to control weeds [5]. It involves planting two or more crops in the same field at the same time or season. This results in higher crop stand, which significantly reduces weed infestation. Though, most farmers do it to increase their yield. Some common intercropping systems include tomatoes and onions, peppers and tomatoes, egg-plants and onions etc. [16] reported that burning is also very common as a method of weed control, mainly used as a method of bush clearing before planting crops. Mulching involves using different types of materials such as black polythene, dry straw and other crop residues for weed control and moisture conservation. Dry grass and black polythene are used to control weeds in vegetables which were found to reduce weeds up to 78% [15]. In Philippines, dry straw is used in combination with manual weeding to control weeds in vegetables, while in India, sugar cane trash is used to control weeds in crop areas. Mulching generally prevents the germination of light sensitive weeds like Ageratum conyzoides, Portulaca oleraceae etc
