Chapter synopsis: In sub-Saharan Africa, weeds are a serious challenge, undermining food security and economic development. Weeds interfere with various human activities. Despite the different classes of weeds based on habitat (terrestrial or aquatic), life cycle (annual or perennial) or morphology (dicots or monocots), they possess common characteristics such as competitiveness, persistence and cause economic losses. This chapter considers integrated management techniques for a range of weeds, including spear grass (Imperata cylindrica), Striga hermonthica and floating aquatic weeds. The chapter examines the role of Chromolaena odorata in the humid tropics and control measures against it, as well as considering weed control in plantain and cassava systems. Finally, the chapter looks ahead to future research trends in this area.
