Chapter synopsis: Diseases caused by a range of established and emerging pathogens such as bacteria, fungi, oomycetes and viruses are among the persistent factors for the reduction in crop yields across sub-Saharan Africa (SSA). Most damaging diseases are caused by introduced exotic pathogens and by locally evolved pathogens infecting introduced crop species. Expansion of the geographic range of established pathogens and introduced new pathogens has caused destructive epidemics and pandemics in large swaths of farmlands during the last three decades in SSA. Since establishment in 1967, IITA has prioritized disease control of its mandate crops and made remarkable progress during the past 50 years to negate their destructive impact through breeding for host resistance, integrated control tactics and preventive management. This chapter summarizes advances in disease control and ongoing efforts in disease diagnostics, surveillance and germplasm health protection.
