| dc.description | The cultivation of avocado (Persea americana Mill) in Ecuador is an important agricultural activity, with specific production areas in provinces such as Carchi, Imbabura, Pichincha, Tungurahua, Azuay, and Loja, located between 1800 and 2600 meters above sea level. This crop faces various challenges, among them, the presence of diseases such as that caused by Phytophthora cinnamomi, a pathogenic oomycete that causes dieback in avocado plants.Symptoms of the disease in avocado crops are severe and involve a number of conditions, such as premature leaf, flower and fruit drop, as well as root and stem rot. These problems can cause significant damage to avocado plantations, affecting both fruit quantity and quality. In addition, it is important to consider the epidemiology of the disease, which highlights the ability of the pathogen to spread through means such as contaminated irrigation water, movement of infected soil and human activity. Therefore, it is critical to implement control and surveillance measures. Several methods have been identified to control the spread of P. cinnamomi, ranging from physical and biological methods to organic and chemical solutions. These range from canopy removal to the use of antagonistic microorganisms, essential oils and biosilica. It is essential to understand the epidemiology of the disease, as well as to adopt preventive measures, such as disinfection of plant material and soil, to reduce the risk of disease spread. | es_ES |

| dc.description.abstract | El cultivo de aguacate (Persea americana Mill) en Ecuador es una actividad agrícola importante, con áreas específicas de producción en provincias como Carchi, Imbabura, Pichincha, Tungurahua, Azuay y Loja, ubicadas entre los 1 800 y 2 600 metros sobre el nivel del mar. Este cultivo enfrenta diversos desafíos, entre ellos, la presencia de enfermedades como la causada por Phytophthora cinnamomi, un oomiceto patógeno que ocasiona la muerte regresiva en las plantas de aguacate. Los síntomas de la enfermedad en los cultivos de aguacate son graves e implican una serie de afecciones, como la caída prematura de hojas, flores y frutos, así como la pudrición de raíces y tallos. Estos problemas pueden causar daños importantes en las plantaciones de aguacate, afectando tanto a la cantidad como a la calidad de la fruta. Además, es importante tener en cuenta la epidemiología de la enfermedad, que pone de relieve la capacidad del patógeno para propagarse a través de medios como el agua de riego contaminada, el movimiento de tierra infectada y la actividad humana. Por lo tanto, es fundamental aplicar medidas de control y vigilancia. Se han identificado varios métodos para controlar la propagación de P. cinnamomi, desde métodos físicos y biológicos hasta soluciones orgánicas y químicas. Éstas van desde la eliminación de la cubierta vegetal hasta el uso de microorganismos antagonistas, aceites esenciales y biosílice. Es fundamental comprender la epidemiología de la enfermedad, así como adoptar medidas preventivas, como la desinfección del material vegetal y del suelo, para reducir el riesgo de propagación de la enfermedad. | es_ES |
