Miscellaneous bacterial diseases
Among the bacterial diseases that attack beans are (1) halo blight (Pseudomonas phaseolicola), which is distributed worldwide and survives in infected seeds and blunt residue. Three to five days after infection, water-soaked spots appear on the lower leaf surface, stem and pods; (2) bacterial wilt (...

| description | Among the bacterial diseases that attack beans are (1) halo blight (Pseudomonas phaseolicola), which is distributed worldwide and survives in infected seeds and blunt residue. Three to five days after infection, water-soaked spots appear on the lower leaf surface, stem and pods; (2) bacterial wilt (Corynebacterium flaccumfaciens) has been registered in the USA, but its existence in L.A. is unknown. Drought and temp more than 32 degrees Celsius are favorable conditions for disease development The bacterium infects plants through the seed and wounds on aerial plant organs and roots; (3) bacterial brown spot (Pseudomonas syringae) produces flecks or necrotic brown lesions on the stem and pods. The bacterium has a wide host range. For efficient disease control, deep plowing, crop rotation and the use of disease-free seeds, adequate chemical products and resistant var. are recommended. The symptoms and damage caused by the disease are illustrated in color. (CIAT) |

(CIAT) Entre las enfermedades bacterianas que atacan el frijol tenemos: 1) anublo de halo (Pseudomonas phaseolicola) que se encuentra presente en todo el mundo, sobrevive en semillas infectadas y en residuos vegetales de los 3-5 dias despues de la infeccion aparecen manchas acuosas en el enves de la hoja, tallos y vainas. 2) el marchitamiento bacteriano del frijol (Corynebacterium flaccumfaciens), esta registrada en los EE.UU., pero se ignora si existe en America Latina. La sequia y las temp a mas de 32 grados centigrados son condiciones favorables para el desarrollo de la enfermedad. La bacteria infecta las plantas a partir de la semilla y de las heridas en los organos aereos de la planta y en las raices. 3) mancha parda bacteriana (Pseudomonas 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 las enfermedades se recomienda la arada profunda, la rotacion de cultivos, y el uso de semilla libre de patogenos, de productos quimicos adecuados y var. resistentes. Se ilustran en color los sintomas y danos causados por las enfermedades.
