| description | A fist of nematodes associated with the roots of beans and other plants is given in table form, the species of Meloidogyne and Pratylenchus being the most common in bean crops in the Americas. Meloidogyne species are prevalent in light sandy soils with good drainage. Length of survival in the soil depends on the nematode species, stage of development of the pathogen, soil type, moisture, and aeration. Color illustrations are given of the symptoms and damage caused by nematode feeding on root systems. They often appear on aerial plant parts which become chlorotic, stunted, burned at the leaf edges, and finally wilt. Crop rotation, deep plowing, the use of fallow, weed control, and flooding for 1-2 wk reduce nematode populations. Chemical control is effective but expensive and requires special equipment for soil applications. Control by plant resistance is the most efficient strategy. (CIAT) |

(CIAT) En forma de cuadro se presenta una lista de los nematodos que se asocian frecuentemente con las raices de frijol y otras plantas, siendo las especies de Meloidogyne y Pratylenchus las mas comunes en los cultivos de frijol en America. Las especies de Meloidogyne predominan en suelos arenosos livianos bien drenados. El periodo de supervivencia en el suelo depende de la especie de nematodo, el estado de desarrollo del patogeno, el tipo de suelo, la humedad y la temp. Se dan ilustraciones a color de los sintomas y danos ocasionados por los nematodos al alimentarse de los sistemas radicales. Estos se encuentran a menudo en las partes aereas de las plantas, las cuales se vuelven cloroticas, raquiticas, presentan quemazones en los bordes de las hojas y terminan marchitandose. La rotacion de cultivos, el arado profundo, el uso de barbecho, el control de malezas y las inundaciones durante 1-2 semanas disminuyen la poblacion de nematodos. El control quimico, aunque efectivo, es costoso y requiere equipo especial para hacer las aplicaciones al suelo. La estrategia mas efectiva es el control mediante el uso de var. resistentes.
