| description | There are various viruses transmitted by aphids that infect beans in almost all countries; (1) BCMV causes yield losses from 35- 98 percent according to the var., time of infection and environmental conditions. The virus can attack any part of the plant and produces 3 types of symptoms: mosaic, necrosis and local lesion resistance. BCMV particles may be transmitted mechanically, in pollen and seed from infected plants, and by insect vectors. Planting date and clean seed production are 2 cultural practices that have been used to reduce the incidence of the disease, as well as the use of resistant var. (2) BYMV can cause yield losses of up to 33 and 41 percent due to the reduction in no. of pods and seeds, resp. The BYMV host range is very wide and can cause chlorotic spots, yellow and green mottling, stunting and necrosis. Alternate hosts of BYMV should be eliminated from bean fields, and chemical control should be used to reduce aphid populations on the crops. The best control method is the utilization of resistant var. (3) Cucumber mosaic virus (CMV) is not considered of economic importance. Infection symptoms consist of a mild mosaic, vein clearing, vein banding, leaf rolling epinasty and/or apical necrosis. CMV particles are easily transmitted mechanically, in seed and by insect vectors. Among control measures are included the planting of healthy seed and crop rotation. The symptoms and damage caused by the disease are illustrated in color. (CIAT) |

(CIAT) Existen varios virus transmitidos por afidos que infectan el frijol y se encuentran en casi todos los paises, 1) El BCMV ocasiona perdidas en el rendimiento que varian de 35-98 por ciento segun la var., la edad al momento de la infeccion, y las condiciones ambientales. El virus puede atacar cualquier parte de la planta y produce 3 clases de sintomas; mosaico, necrosis, y resistencia a lesiones locales. Las particulas del BCMV se pueden transmitir mecanicamente, en el polen y en la semilla de las plantas infectada y por medio de insectos vectores. La epoca de siembra y la produccion de semilla limpia son 2 de las practicas culturales que se han utilizado para disminuir la incidencia de la enfermedad como tambien el uso de var. resistentes. 2)BYMV: puede ocasionar perdidas en el rendimiento al reducir el no. de vainas y semillas en 33 y 41 por ciento resp. El rango de hospedante del virus es sumamente amplio y puede ocasionar en las plantas manchas cloroticas, moteado verde y amarillo, raquitismo y necrosis. Todo hospedante del BYMV se debe eliminar de los cultivos de frijol y el control quimico se debe utilizar para reducir las poblaciones de afidos en los cultivos. Las var. resistentes es el mejor metodo de control. 3) El virus del mosaico del pepino (CMV) no se considera economicamente importante. Los sintomas de la infeccion son un mosaico moderado, aclaramiento de las nervaduras, formacion de bandas en las nervaduras, enrollamiento de las hojas, epinastia y/o necrosis apical. Las particulas del CMV se transmiten con facilidad mecanicamente, por medio de la semilla y de insectos vectores. Entre las medidas de control se incluyen la siembra de semilla sana y la rotacion de cultivos. Se ilustran en color los sintomas y danos causados por la enfermedad.
