  • 16. Concluding remarks  Recurrent wheat rusts (stripe rust) epidemics is a key constraint to Ethiopian farmers and beyond  The breakdown of resistance is a common after two or three years of cultivation  Adaptation to warmer climate (Climate change) widening epidemics  The development & deployment of resistance + IDM is of concern  Establishments and strengthening of molecular labs & C. Building  National, regional and international collaboration & networking 16
