    Abstract/Description
    Bacterial wilt (Corynebacterium flaccumfaciens) has been registered in the USA, but its existence in Latin America is unknown. Drought and temp. more than 32 degrees C are favorable conditions for disease development. The bacterium infects plants through the seed and wounds on aerial plant organs and roots. Control measures suggested include cultural practices and the use of resistant var. Bacterial brown spot (Pseudomonas syringae pv. syringae) produces flecks or necrotic brown lesions on the stem and pods. The bacterium has a wide host range. For efficient disease control, adequate chemical products and the use of resistant var. are recommended. Bean wildfire (P. syringae pv. tabaci) occurs in different bean-growing regions of Brazil and Argentina. Lesions on leaves are small, necrotic, circular to angular, light to dark brown, and surrounded by circular bright halos. No specific control measures are known. The symptoms and damage caused by the disease are illustrated in color. A list of other bacteria pathogenic to beans is also included. (CIAT)
     
    El marchitamiento bacteriano del frijol (Corynebacterium flaccumfaciens), se registra en los EE.UU., pero se ignora si existe en America Latina. La sequia y las temp. superiores a 32 grados C son condiciones favorables para el desarrollo de la enfermedad. La bacteria infecta las plantas a traves de la semilla y de las lesiones en los organos aereos de la planta y en las raices. Se sugieren medidas de control como practicas culturales y el uso de var. resistentes. La mancha parda bacteriana (Pseudomonas syringae pv. syringae) produce puntos o lesiones necroticas de color cafe en el tallo y en las vainas. La bacteria presenta un amplio rango de hospedantes. Para un buen control de la enfermedad se recomienda el uso de productos quimicos adecuados y de var. resistentes. La quemazon del tabaco (P. syringae pv. tabaci) del frijol ocurre en diferentes regiones productoras de frijol de Brasil y Argentina. Las lesiones en las hojas son pequenas, necroticas, de forma circular a angular, de color cafe claro a cafe oscuro y rodeadas por halos circulares brillantes. No se conocen medidas especificas de control. Se ilustran a color los sintomas y danos causados por las enfermedades. Tambien se incluye una lista de otras bacterias patogenas al frijol. (CIAT)
