Spatial distribution of the potential risk for avocado wilting disease, caused by Phytophthora cinnamomi in the subregion of Montes de Maria, Colombia
Avocado wilting or root rot, caused by the oomycete Phytophthora cinnamomi Rands, is the most limiting disease of avocado crops around the world. Montes de Maria (MM) is the main producer region of avocado in the Colombian Caribbean. Avocado producing areas in MM are decreasing in an inverse trend c...

| description | Avocado wilting or root rot, caused by the oomycete Phytophthora cinnamomi Rands, is the most limiting disease of avocado crops around the world. Montes de Maria (MM) is the main producer region of avocado in the Colombian Caribbean. Avocado producing areas in MM are decreasing in an inverse trend compared with the increasing hectarage world and nation-wide. Decreasing hectarage in MM is associated with phytosanitary problems, specifically the avocado wilting caused by P. cinnamomi. Climate is one of the main abiotic factors determining spatial distribution of species. For plant-pathogens, environmental conditions determine host-colonization. Under this scenario, the aim of this study was to estimate the spatial distribution of the avocado root-rot risk in the subregion of Montes de Maria, Colombia. This estimation was based on data for the presence of shoot dieback, a characteristic, easily identifiable symptom of root rot caused by P. cinnamomi. This symptom exhibits a high correlation with disease incidence and severity. A Maxent model was used to estimate the spatial distribution of the risk, showing a high statistical validation (test AUC>0.9). This model identified areas with a high risk for occurrence of branch dieback and, consequently, root rot. Areas with a higher risk of root rot were found at the higher altitudes, with lower temperatures in the coldest trimester (BIO11 ~22°C), and in the warmest one (BIO10 ~24°C), with higher rainfall during the dry season (BIO17 - BIO14). |

El marchitamiento del aguacate, causado por el oomycete Phytophthora cinnamomi Rands, es la enfermedad más limitante del cultivo a nivel mundial. Montes de María (MM) es la principal región productora de aguacate del Caribe Colombiano. El área de producción de aguacate en esta región, se encuentra en declive en contraposición a la tendencia mundial y nacional. Esta disminución en MM ha sido asociada a problemas sanitarios, específicamente al marchitamiento del aguacate ocasionado por P. cinnamomi. El clima es uno de los factores más importantes que determinan la distribución espacial de una especie y en el caso de los patógenos determina el nicho que facilita la colonización del hospedero. En este contexto, se tiene como propósito estimar la distribución espacial del riesgo de marchitamiento del aguacate en la subregión Montes de María. Esta estimación se realizó a partir de los datos de presencia del síntoma de marchitamiento de yemas, característico de la pudrición radicular por P. cinnamomi. Este síntoma exhibió una alta correlación con la incidencia y la severidad de la enfermedad evaluada por fincas. El modelo Maxent usado para estimar la distribución espacial de riesgo muestra una alta validación estadística (test AUC≥0,9). Este modelo ha permitido predecir las zonas donde el riesgo a pudrición radicular es más alto. Las características de las áreas con el mayor riesgo de pudrición radicular son aquellas localizadas a mayor altitud, con las temperaturas más bajas en el trimestre más frío (BIO11 ~22°C) y en el más caluroso (BIO10 ~24°C) y con la precipitación más alta durante la estación seca (BIO17 - BIO14).
