Estado actual de la Marchitez por Fusarium oxysporum f. sp. cubense (Foc) raza tropical 4 (R4T), en el cultivo de Banano, en el continente americano

The information collected details the current situation of Fusarium wilt, race 4 in banana cultivation in the American continent. The fungus that causes this disease is Fusarium oxysporum f. sp. cubense, being a disease that affects the banana crop, the same one that has the capacity to obstruct the vascular system of the plantations. The conclusions determine that one of the most important crops both to generate income is banana. The attack of diseases such as wilt or Panama disease, represents a threat to crop production. Fusarium oxysporum f sp. cubense FOC is the cause of this disease, considered the most harmful and economically significant disease that affects the genus Musa; TR4 may pose a real and significant threat to the banana industry, although the situation is very different compared to the period when Panama disease was prevalent. The propensity of the Foc pathogen for long-term survival in soil and the lack of a reliable treatment to eradicate it are major concerns. Fusarium wilt is the most devastating Musaceae disease in history. As a result, the plant withers and eventually dies. In addition, infected soil adheres to shoes or tires of moving vehicles, and the fungus can in turn spread through surface water, farm machinery, root entanglements, and implements. Currently, no ideal chemical control has been found for this disease.

La información recopilada detalla la situación actual de la marchitez por Fusarium, raza 4 en el cultivo de banano en el continente americano. El hongo que causa esta enfermedad es Fusarium oxysporum f. sp. cubense, siendo una enfermedad que afecta al cultivo de banano, la misma que tiene la capacidad de obstruir el sistema vascular de las plantaciones. Las conclusiones determinan que uno de los cultivos más importantes tanto para generar ingresos es el banano. El ataque de enfermedades como la marchitez o el mal de Panamá, representa una amenaza para la producción del cultivo. Fusarium oxysporum f sp. cubense FOC es la causa de esta enfermedad, considerada como la más dañina y económicamente significativa que afecta al género Musa; R4T puede representar una amenaza real y significativa para la industria bananera, aunque la situación es muy diferente en comparación con el período en que prevalecía el Mal de Panamá. La propensión del patógeno Foc a la supervivencia a largo plazo en el suelo y la falta de un tratamiento fiable para erradicarlo son motivos principales de preocupación. Marchitez por Fusarium es la enfermedad de Musaceae más devastadora de la historia. Como resultado, la planta se marchita y finalmente muere. Además, la tierra infectada se adhiere a los zapatos o llantas de los vehículos en movimiento y a su vez el hongo puede dispersarse a través de aguas superficiales, maquinaria agrícola, enredos de raíces e implementos. Actualmente no se ha encontrado control químico ideal para esta enfermedad.
