| Description | Beans are grown in Africa in a wide range of environments, mainly in the cool highlands of central and tropical eastern Africa, leading to a diversity of cropping systems and agronomic constraints to production. Beans are cultivated for large-scale production or home consumption either in monoculture or in association. The main constraints to production are poor agronomic practices, soil infertility, lack of improved cv., water stress, weed competition, and diseases and pests. Main diseases affecting bean crops in Africa include viral diseases (BCMV, SBMV, BGMV, and BYMV), bacterial diseases (bacterial wilt and bacterial brown spot), and fungal diseases (angular leaf spot, anthracnose, rust, Ascochyta blight, and floury leaf spot). Suggestions for disease management are given, highlighting the use of integrated control. Estimates of annual production per region and crop losses due to pathogens are given in table form. (CIAT) El frijol se cultiva en Africa en un amplio rango de ambientes, principalmente en las areas montanosas templadas de las regiones central y oriental tropical de Africa, lo cual supone diversos sistemas de cultivo y limitaciones agronomicas a la produccion. El frijol se cultiva para produccion en gran escala o para consumo domestico, sea en monocultivo o en asociacion. Las principales limitaciones a la produccion son practicas agronomicas inadecuadas, infertilidad del suelo, falta de cv. mejorados, estres hidrico, competencia de malezas y plagas y enfermedades. Las principales enfermedades que afectan el cultivo del frijol en Africa son las de tipo viral (BCMV, SBMV, BGMV y BYMV), las bacterianas (anublo bacteriano y mancha parda bacteriana) y las fungicas (mancha angular, antracnosis, roya, anublo por Ascochyta y mancha harinosa). Se dan sugerencias para manejo de enfermedades, destacando el uso de control integrado. Se incluyen en forma de tabla estimativos de produccion anual por region y perdidas de cosecha por patogenos.
