| dc.description | Banana cultivation is a plant that adapts to variable tropical climates, is perennial and native to Asia. "In Ecuador, three types of bananas are grown, the most important being the so-called" Cavendish "banana, followed by the" Orine Guineo "and the purple guineo called" Banana Rose. " The Ecuadorian banana market is diversified, exporting the fruit to the European Union USA Russia, Southern Cone as main markets and 11% to marginal markets. In 2016, banana exports amounted to USD 2,734.16 million. In Costa Rica and Ecuador, BSV has caused severe symptoms in cultivars of the cavendish group, which has made them unfit for commercialization, causing distortion in the pseudostem and consequently an increased susceptibility to bacterial infections. Banana is a fundamental crop in the country's economy, generating income in turn source of work to thousands of families, being a sustainable crop for the country Ecuador. The main problem in Ecuador is that there is no technology to develop genetic improvement in banana varieties and prevention methods are very basic such as the use of treated plants, eradication of infested plantations and prevention of vector agents. The main objective was to describe the integral practices in commercial banana plantations to minimize losses due to (Banana streak virus - BSV). In the banana farms of the province of Los Ríos, the Banana Streak Virus - BSV is defined as one of the viruses that specifically affects the musaceae generating large economic losses, reduction of arable hectares and low yield in the agricultural sector. During the supervision of the Treasury, the different symptoms were observed, which explained to us that these may disappear or appear at different times and not the entire leaf area can show the symptoms of the striatum. The collaborators of the Laura Isabella I Hacienda mentioned that The most contagious stage is, during the winter state, since different insect pests manifest and increase the presence of cochineal being this one of the transmitters of the BSV. There are no studies that ensure the control of double-stranded plant viruses, therefore it cannot be considered as a potential agent for the elimination of BSV. | es_ES |

| dc.description.abstract | El cultivo de banano es una planta que se adapta a variables climas tropicales, es perenne y originario de Asia. " En el Ecuador se cultivan tres tipos de banano siendo el más importante el denominado banano "Cavendish", seguido por el "Guineo Orito" y el guineo morado llamado "Banana Rose. El mercado del banano ecuatoriano es diversificado, exportándose la fruta a la Unión Europea USA Rusia, Cono Sur como mercados principales y el 11% a mercados marginales. el año 2016 las exportaciones de banano fueron de USD 2.734,16 millones. En Costa Rica y Ecuador el BSV ha causado síntomas severos en cultivares del grupo Cavendish, que los ha hecho no aptos para su comercialización, provocando distorsión en el pseudotallo y por consiguiente un aumento de la susceptibilidad a infecciones bacterianas. El banano es un cultivo fundamental en la economía del país, generando ingresos a su vez fuente de trabajo a miles de familia, siendo un cultivo sostenible para el país Ecuador. La principal problemática en el Ecuador es que no consta con tecnología para desarrollar mejoramiento genético en variedades de banano y los métodos de prevención son muy básicos como el uso de plantas tratadas, erradicación de plantaciones infestadas y prevención de agentes vectores. El objetivo principal fue describir las practicas integrales en plantaciones comerciales de banano para minimizar las perdidas por (Banana Streak virus - BSV). En las fincas bananeras de la provincia de los Ríos el Banana Streak Virus - BSV es definida como uno de los virus que afecta específicamente a las musáceas generando grandes pérdidas económicas, reducción de hectáreas cultivables y bajo rendimiento en el sector agrícola. Durante la supervisión de la Hacienda se observó los diferentes síntomas, el cual nos explicaban que estos pueden desaparecer o aparecer en diferentes épocas y no toda el área foliar puede mostrar los síntomas del estriado. Los colaboradores de la Hacienda Laura Isabella I mencionaron que la etapa más contagiosa es, durante el estado invernal, ya que se manifiestan diferentes insectos plagas e incrementa la presencia de cochinilla siendo este uno de los transmisores del BSV. No existen estudios que aseguren el control de los virus de doble cadena de plantas, por lo tanto, no puede ser considerado como un potencial agente para la eliminación de BSV. | es_ES |
