Many factors can severely affect beans during their growth cycle: (1) Parasitic plants, such as Cuscuta epithymum and Cassytha filiformis, can reduce yields. (2) Various environmental conditions including frost, extreme conditions of high or low MC, sudden changes in soil and air temp and periods of...

| description | Many factors can severely affect beans during their growth cycle: (1) Parasitic plants, such as Cuscuta epithymum and Cassytha filiformis, can reduce yields. (2) Various environmental conditions including frost, extreme conditions of high or low MC, sudden changes in soil and air temp and periods of intense sunlight and wind can damage bean seedlings or mature plants. (3) Variations in soil properties and drainage may produce marked differences in plant appearance and vigor. (4) Genetic and physiological abnormalities may cause obvious or subtle change in plant development. (5) Improper pesticide and fertilizer applications and toxic air pollutants may cause chemical damage. Sometimes the symptoms produced by these factors are confused with those produced by insects, diseases, nematodes and nutritional disorders. A complete history of all factors relevant to bean production in a specific region is required to identify the causal agent correctly. (CIAT) |

(CIAT) Muchos factores pueden afectar severamente el frijol durante su ciclo de crecimiento: 1) Las plantas parasitas, tales como Cuscuta epithymum y Cassytha filiformis, pueden reducir los rendimientos. 2) Diversas condiciones ambientales incluyendo las heladas, las condiciones extremas de exceso o falta de humedad, los cambios repentinos en la temp del suelo y del aire y los periodos de gran intensidad solar y viento pueden ocasionar danos en las plantulas y plantas adultas de frijol. 3) Las variaciones en las propiedades y el drenaje del suelo pueden producir diferencias acentuadas en la apariencia y vigor de las plantas. 4) Las anormalidades geneticas y fisiologicas pueden ocasionar cambios notorios o tenues en el desarrollo de las plantas. 5) Las aplicaciones inapropiadas de pesticidas y fertilizantes y los contaminantes toxicos del aire pueden producir danos quimicos. Algunas veces los sintomas producidos por estos factores se confunden con los producidos por los insectos, enfermedades, nematodos y desordenes nutricionales. Para identificar correctamente el agente causal se requiere una historia completa de todos los factores que inciden en la produccion del frijol en una region especifica.
