| description | The different alternatives for disease control in cassava, registered as efficient and considered as possible candidates for inclusion in technological packages for cassava cultivation, are summarized. Certain specific characteristics of cassava and its cultivation that should be considered when developing and applying control measures are listed. Successful cultural control measures are crop rotation, planting in furrows, elimination of crop residues, adequate spacing between plants, selection of planting material, weed control, and solarization. Although genetic (varietal) disease control in cassava is the most efficient and less expensive method for farmers, the process of developing improved clones can take 10 yr or longer of continuous evaluation. Var. resistance to all cassava diseases studied has been found. Since the commercial cycle of cassava is relatively long (8-24 mo.), chemical disease and pest control is uneconomical; furthermore, cassava farmers generally have low incomes and the use of agrochemicals is limited. However, preplanting treatment of cuttings has had excellent results. Biological disease control is relatively recent, but good results have been obtained with Darluca filum in Uromyces, Pseudomonas putida in CBB and superelongation, and bacterias in Diploidia manihotis. Pathogens have also been eradicated by physical means such as heat treatment (witches' broom, common mosaic, Caribbean mosaic, frog skin) and microwaves (fungi and bacterias affecting the seed). The importance of quarantine measures for the movement of cassava propagation materials is highlighted. (CIAT) |

(CIAT) Se resumen las diferentes alternativas que para el control de enfermedades en yuca se han registrado como eficientes y que podrian tenerse en cuenta al proyectar paquetes tecnologicos para la produccion de ese cultivo. Se enumeran ciertas caracteristicas especificas de la yuca y su cultivo que se deben tener en cuenta para desarrollar y aplicar medidas de control. Las medidas de control cultural que ha tenido exito son rotacion de cultivos, siembra en caballones, eliminacion de residuos de cosecha, espaciamiento adecuado entre plantas, seleccion del material de siembra, control de malezas y solarizacion. Aunque el control genetico (varietal) de enfermedades en yuca es el metodo mas eficiente y menos costoso para el productor, el proceso de desarrollar clones mejorados puede tomar 10 o mas anos de evaluaciones continuas. Se ha encontrado resistencia var. para todas las enfermedades de la yuca que se han investigado. Como el ciclo comercial de la yuca es relativamente largo (8-24 meses), el control quimico de enfermedades y plagas es antieconomico; ademas, los productores de yuca generalmente son de escasos recursos y la utilizacion de agroquimicos es limitada. Sin embargo, el tratamiento presiembra de estacas ha tenido excelentes resultados. El control biologico de enfermedades es relativamente reciente, pero se han obtenido buenos resultados con Darluca filum en Uromyces, Pseudomonas putida en CBB y superalargamiento y bacterias en Diploidia manihotis. La erradicacion de patogenos tambien se ha realizado utilizando medios fisicos como el calor (superbrotamiento, mosaico comun, mosaico caribeno, cuero de sapo) y las microondas (hongos y bacterias que afectan las semillas). Se destaca la importancia de las reglamentaciones cuarentenarias en cuanto al movimiento de material de propagacion de yuca.
