| Description | Diseases were identified as the most important factor limiting bean production as early as 1960. Research on these diseases in Uganda focused on the important ones as identified by pathologists. The progress presented here summarizes the work carried out on these diseases since 1960. Between 1960-1984 races of Colletotrichum lindemuthianum and Uromyces appendiculatus were identified. The survival mechanism and transmission of angular leaf spot was established and the use of fungicides in the control of diseases was studied. Benlate gave control to angular leaf spot while rust was best controlled by dithane M45. Breeders' materials were evaluated for diseases in different areas. Since 1985 more diversification in pathology research has occurred. Work has been done on ascochyta blight, CBB, BCMV, halo blight as well as on effect of intercropping on diseases and crop loss assessment. Evaluation of breeders' materials and disease nurseries is also being carried out. (AS) A comienzos de 1960, se identifico a las enfermedades como el principal limitante de la produccion de frijol. La investigacion en estas enfermedades en Uganda se enfoco en las mas importantes que habian identificado los patologos. Se resumen los trabajos realizados en estas enfermedades desde 1960. Entre 1960 y 1984, se identificaron razas de Colletorrichum lindemuthianum y Uromyces appendiculatus. Se establecio el mecanismo de supervivencia y la transmision de la mancha foliar angular y se estudio el uso de fungicidas para el control de enfermedades. El benomil y el mancozeb controlaron la mancha foliar angular y la roya, resp. Se evaluo en varias areas la reaccion a enfermedades de los materiales seleccionados por los mejoradores. Desde 1985 se ha diversificado la investigacion en patologia de frijol. Se ha trabajado en mancha por Ascochyta, anublo bacteriano comun, BCMV, anublo de halo, y en el efecto de los cultivos asociados en las enfermedades y la evaluacion de perdidas del cultivo. Tambien se estan evaluando los materiales de los mejoradores y los viveros de enfermedades. (RA- CIAT) |
