| dc.description | In the phytosanitary field, one of the major limitations detected in orange crop production is the presence of the citrus canker disease caused by the bacterium X. citri, which is distributed in some countries of the world with greater indecency and severity; although in Ecuador there are still no evident reports of the presence of the disease in orange plantations, and it is important to consider this disease as a quarantine pest. The information obtained was paraphrased, summarized and analyzed in order to obtain relevant information on the incidence of citrus canker (X. citri) in the orange crop (C. sinensis) in Ecuador. From the above, it was determined that citrus canker is a disease that can occur throughout the year, affecting seedlings and young trees, which have a high production of vegetative shoots. The symptoms on the leaves are young lesions with a yellow halo and wet edges, which disappear with age; the lesions measure about 2-10 mm, although in favorable situations they unite and affect larger areas. The disease can cause extreme defoliation, branch death and premature fruit drop; the latter can also lose their commercial cost due to damage to the peel. The X. citri bacterium is spread with the help of water present on the surface of the foliage, which drips and splashes the new shoots; the bacteria in the water depends on the age of the lesion and varies between one hundred-1000 million bacterial cells consisting of droplets. Control measures for citrus canker disease (X. citri) in orange cultivation involve various activities such as exclusion, eradication, integrated control and disinfection. | es_ES |

| dc.description.abstract | En el ámbito fitosanitario una de las mayores limitantes detectadas dentro de la producción del cultivo de naranja es la presencia de la enfermedad cancro cítrico causada por la bacteria X. citri, misma que está distribuida en algunos países del mundo con mayor indecencia y severidad; aunque en Ecuador aun no existen reportes evidentes de la presencia de la enfermedad en plantaciones de naranja, siendo importante considerar a esta enfermedad como una plaga cuarentenaria. La información obtenida fue parafraseada, resumida y analizada a fin de obtener información relevante sobre la incidencia del cancro cítrico (X. citri) en el cultivo de naranja (C. sinensis) en el Ecuador. Por lo anteriormente detallado se determinó que el cancro cítrico es una enfermedad que puede presentarse durante todo el año, afectando plántulas y árboles jóvenes, los mismos que presentan una producción alta de brotes vegetativos. Los síntomas en las hojas son lesiones jóvenes que tienen un halo amarillo y bordes húmedos, que desaparecen con la edad; las lesiones miden unos 2-10 mm, a pesar de que en situaciones favorables se unen y afectan a superficies mayores. La enfermedad puede provocar una defoliación extrema, la muerte de las ramas y la caída prematura de los frutos; estos últimos pueden perder además su coste comercial debido a los daños en la cáscara. La bacteria X. citri se disemina con la ayuda del agua presente en la superficie del follaje, que gotea y salpica los nuevos brotes; la bacteria en el agua depende de la edad de la lesión y varía entre cien-1000 millones de células bacterianas consistentes en gota. Las medidas de control para la enfermedad cancro cítrico (X. citri) en el cultivo de naranja involucra diversas actividades tales como: exclusión, erradicación, control integrado y desinfección. | es_ES |
