La mayoria de las variedades de alto rendimiento en Nigeria son susceptibles al anublo bacterial. La mayor incidencia al ataque se registra durante la epoca lluviosa. El organismo causal es Xanthomonas manihotis. Los sintomas caracteristicos de la enfermedad son: marchitex de las hojas, defoliacion y muerte descendente acompanada de exudaciones de color amarillo-crema de las partes afectadas. Se incluyen fotografias de los sintomas de la enfermedad. Para el control se sugieren las siguientes medidas culturales: 1) Uso de material vegetativo libre de enfermedad; 2) epocas de siembra adecuadas de acuerdo a la distribucion de lluvias en el area; 3) una fertilizacion balanceada; 4) utilizar variedades resistentes como Nwaugo y Aburu-Asuo que han mostrado tolerancia en esta zona; 5) la aplicacion de medidas sanitarias como arrancar y quemar las plantas que presenten la enfermedad; y 6) rotacion de cultivos.

Most high-yielding varieties of cassava in Nigeria are susceptible to bacterial blight, most serious outbreaks occur during the rainy season. The causal agent is Xanthomonas manihotis. Characteristic symptoms of the disease are wilting of leaves, defoliation and dieback, accompanied by a creamy yellow exudation from infected parts. Photos showing disease symptoms are included. Suggested control measures are as follows, (1) use disease-free cuttings, (2) plant at a time that will permit plants to establish well before heavy rains begin, (3) use balanced fertilizer, (4) use resistant varieties such as Nwaugo and Aburu-asuo, which have proven to be tolerant in this area, (5) rogue and burn diseased plants, and (6) rotate crops.
