Oídio (Sphaerotheca pannosa) y su incidencia en el cultivo de rosas de exportación en el Ecuador

Powdery mildew, caused by the fungus Sphaerotheca pannosa var. rosae, poses a serious threat to rose production and export in Ecuador and globally. This disease affects the quality of roses by reducing production and weakening plants, resulting in significant economic losses for producers. Despite the widespread use of agrochemicals as the primary method for control, this practice presents challenges in terms of sustainability and environmental risks. In this context, this research focuses on identifying integrated strategies for powdery mildew control in export rose cultivation in Ecuador. A detailed study was conducted on the edaphoclimatic characteristics that favor disease development, as well as integrated powdery mildew management, which includes appropriate cultural practices, rational use of fungicides, and biological control agents. The findings revealed that powdery mildew significantly affects export rose cultivation in Ecuador, impacting both the quality and production of flowers. However, various control measures were identified that can be implemented sustainably, such as integrated powdery mildew management, which combines different control methods to reduce disease incidence and severity. In conclusion, this research offers practical recommendations for Ecuadorian floricultural producers, emphasizing the importance of applying cultural control measures and using fungicides appropriately to minimize environmental impacts and ensure sustainable production of export roses.

El Oídio, causado por el hongo Sphaerotheca pannosa var. rosae, representa una seria amenaza para la producción y exportación de rosas en Ecuador y a nivel mundial. Esta enfermedad afecta la calidad de las rosas al disminuir la producción y debilitar las plantas, generando importantes pérdidas económicas para los productores. A pesar de que el uso prolongado de agroquímicos es la metodología más empleada para su control, esta práctica plantea desafíos en términos de sostenibilidad y riesgos ambientales. En este contexto, esta investigación se centra en identificar estrategias integradas para el control del Oídio en el cultivo de rosas de exportación en Ecuador. Se llevó a cabo un estudio detallado de las características edafoclimáticas que favorecen el desarrollo de la enfermedad, así como del manejo integrado del Oídio, que incluye prácticas culturales adecuadas, uso racional de fungicidas y agentes de control biológico. Los hallazgos revelaron que el Oídio incide significativamente en el cultivo de rosas de exportación en Ecuador, afectando tanto la calidad como la producción de las flores. Sin embargo, se identificaron diversas medidas de control que pueden implementarse de manera sostenible, como el manejo integrado del Oídio, que combina diferentes métodos de control para reducir la incidencia y severidad de la enfermedad. En conclusión, esta investigación ofrece recomendaciones prácticas para los productores florícolas de Ecuador, destacando la importancia de aplicar medidas de control cultural y utilizar fungicidas de manera adecuada para minimizar los impactos ambientales y garantizar una producción sostenible de rosas de exportación.
