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 monocul...

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 g...

Seeds provide an efficient method for disseminating pathogenic organisms to different locations; more than 50 percent of the major bean diseases are seed borne. Mechanical damage, which may occur during harvesting, threshing and/or planting can affect seed viability, germination, and result in co...

La semilla constituye un metodo eficiente de diseminacion de organismos fitopatogenos a diversas localidades; mas de 50 por ciento de las principales enfermedades del frijol son transmitidas por la semilla. El dano mecanico que ocurre durante la cosecha, trilla y/o siembra tambien puede afectar l...

Cassava is an important crop in many parts of the tropics, but it plays a particularly vital role in sustaining food security in sub-Saharan Africa. Diseases are the greatest biotic constraint to cassava production worldwide. Although the diversity of cassava pathogens is greatest in Latin Americ...

Bean crops are attacked by several viruses transmitted by insects among which are: (1) the alfalfa mosaic virus (aphids); susceptibility is correlated with plant age; (2) curly top (Circulifer tenellus); the best control measure is the utitilization of resistant var.; (3) bean summer death (Orosi...
