| dc.description | The pachaco tree (Schizolobium parahybum) is a forest species introduced to the country in the 50s, presenting a rapid adaptability in the territory in addition to its benefits as a raw material to make products, however, in the 80s a disease called regressive death emerged. , the same one that attacks in a descending way causing the loss of the green coloration of the leaves, making them chlorotic until the tree is completely killed. The disease is composed of a fungal complex, and to identify the genera that comprise it, studies of infected trees have been carried out in different areas of the country, resulting in the discovery of four genera of fungi such as: Graphium sp., Macrophoma sp., Fusarium sp., Ceratocystis of paradoxical species, and moniliformis. The main genus of fungus that acts with the highest volume of necrosis is Ceratocystis paradoxa, followed by C. moniliformis and Macrophoma sp, the latter two in less statistical difference than the first, but considered capable of infecting the plant. Among the potential affected by the disease are the ecological and economic, the first because this tree is widely used in agroforestry systems and the second because its wood is used to make products such as plywood, doors, paper pulp, toys, models. | es_ES |

| dc.description.abstract | El árbol pachaco (Schizolobium parahybum) es una especie forestal introducida al país en los años 50, presentando características de gran adaptabilidad en el territorio principalmente en los trópicos ecuatorianos, también la de su madera como materia prima para elaborar productos, sin embargo, en los años 80 surgió una enfermedad denominada muerte regresiva, la misma que ataca de forma descendente ocasionando la pérdida de la coloración verde de las hojas tornándolas cloróticas hasta el punto de causar completamente la muerte del árbol. La enfermedad está compuesta por un complejo fúngico, y para identificar los géneros que la integran se han realizado estudios de árboles infectados en diferentes zonas del país, dando como resultado el hallazgo de cuatro géneros de hongos como: Graphium sp., Macrophoma sp., Fusarium sp., Ceratocystis de especies paradoxa, y moniliformis. El principal género de hongo que actúa con mayor volumen de necrosis es Ceratocystis paradoxa, seguido de C. moniliformis y Macrophoma sp estos dos últimos en menor diferencia estadística que la primera, pero considerados capaces de infectar a la planta. Entre los potenciales afectados por la enfermedad se encuentran los ecológicos y económicos, el primero debido a que este árbol es muy usado en sistemas agroforestales y el segundo porque su madera es utilizada para elaborar productos como contrachapados, puertas, pulpa de papel, juguetes, maquetas. | es_ES |
