Common and fuscous blights
Common blight (Xanthomonas phaseoli) and fuscous bright (Xanthomonas phaseoli var. fuscans) are the major bacterial diseases of beans. The 2 organisms are found frequently in association and are present in numerous bean production regions of the world. High temp and RH are favorable conditions for the development of the disease. The infection by the bacteria produces water spots on the leaves, stems, pods and seeds. The disease can be controlled by cultural practices such as the use of disease-free seed, proper crop rotation and deep plowing; various chemical products have been used in seed treatment or as a foliage protectant before the infection becomes severe; and by the utilization of resistant var. The symptoms and damage caused by the diseases are illustrated in color. (CIAT)

(CIAT) Las principales enfermedades bacterianas del frijol son el anublo comun (Xanthomonas phaseoli) y el anublo fusco (X. phaseoli var. fuscans). Los 2 organismos se encuentran con frecuencia en asociacion y se hallan presentes en numerosas regiones productoras de frijol en el mundo. La temp y la humedad relativa alta son condiciones favorables para el desarrollo de la enfermedad; la infeccion por la bacteria produce manchas humedas en las hojas, tallos, vainas, y semillas. El control de las enfermedades se puede hacer por practicas culturales, tales como el uso de semilla libre de patogenos, la apropiada rotacion de cultivos y una arada bien profunda; varios productos quimicos se han utilizado en el tratamiento de la semilla o para proteger el follaje antes de que la infeccion tome caracteristicas severas; y la utilizacion de var. resistentes. Se ilustran en color los sintomas y danos causados por las enfermedades. (CIAT) 1980 2017-06-20T08:51:10Z 2017-06-20T08:51:10Z Book Chapter Yoshii, K.1980. Common and fuscous blights .
