    Abstract/Description
    Beans are attacked by a large no. of plant pathogens and insect pests, many of which can reduce yields drastically. Farmers with small land holdings usually have limited resources but produce most of the beans in L.A. Control strategies feasible for these growers may be restricted to those strategies that do not require large cash inputs; hence breeding for resistance may be the most desirable alternative available. National and international bean production programs, must accurately identify yield constraints prevalent in specific producton regions to provide more efficient use of the large amount of manpower, research expenditure and time required to implement resistance breeding. Stability of resistant materials can be improved with an integrated control strategy consisting of resistance, cultural practices, chemicals and clean seed production for those diseases in which resistance does not confer immunity to infection. This Integrated control strategy must be adapted to specific regional problems. A more systematic collection of information is necessary to evaluate the costs and probability of success for control strategies so that the pathology, entomology and breeding reseach at the expt station is more applicable and quickly available to farmers.

    El frijol es atacado por un gran no. de organismos fitopatogenos y plagas, muchas de las cuales disminuyen los rendimientos significativamente. Los agricultores que poseen pequenas parcelas tienen generalmente ingresos muy limitados pero producen casi todo el frijol en America Latina. Las estrategias de control factibles para estos agricultores estan restringidas a aquellas medidas que no requieren grandes inversiones; de ahi que el mejoramiento por resistencia sea una de las alternativas disponibles mas deseables. Los programas nacionales e internacionales de produccion de frijol deben identificar en forma precisa los limitantes del rendimiento prevalentes en regiones productoras especificas, a fin de utilizar eficientemente el potencial humano, las inversiones en investigacion y el tiempo requerido para implantar el mejoramiento por resistencia. La estabilidad de los materiales resistentes se puede mejorar mediante una estrategia de control integrado que consiste en resistencia, practicas culturales, productos quimicos y produccion de semilla limpia para aquellas enfermedades para las cuales la resistencia no confiere inmunidad a la infeccion. Este sistema de control integrado debera adaptarse a los diferentes problemas especificos regionales. Se requiere una recoleccion mas sistematica de informacion para evaluar los costos y posibilidades de exito de los sistemas de control, con el objetivo de que la investigacion en patologia, entomologia y mejoramiento genetico en la estacion experimental sea mas util y rapidamente apicable por los agricultores.
