Summary: | Frosty pod rot (Moniliophthora roreri) disease damages cocoa fruits at any stage of development, causing abandonment of the crop, demolition and change of land use. The objective of this study was to optimize the management of frosty pod rot of cocoa based on chemical, cultural and varietal use control practices. In Mapastepec, Chiapas, five plots, each with 24 cocoa trees, were evaluated in a completely randomized design with factorial arrangement. Productivity and disease incidence variables were evaluated on CATIE-R1, CATIE-R4 and CATIE-R6 varieties, each with five management types and eight repetition. The interaction between genotype, cultural and phytosanitary management with alternate spraying of azoxystrobin with flutriafol and fertilization increased the number of cocoa pods by 48.5% and reduced the incidenceof Moniliophthora roreriby 30.3%.
La moniliasis (Moniliophthora roreri) daña los frutos de cacao en cualquier fase de desarrollo, ocasionando el abandono del cultivo, derribo y cambio de usos de suelo. El objetivo del presente estudio fue optimizar el manejo de la moniliasis del cacao con base en prácticas de control químico, cultural y uso de variedades. En Mapastepec, Chiapas se evaluaron cinco parcelas, cada una con 24 árboles de cacao en un diseño completamente al azar con arreglo factorial. Las variables de productividad e incidencia de la enfermedad se evaluaron en las variedades CATIE-R1, CATIE-R4 y CATIE-R6, cada una con cinco tipos de manejo y ocho repeticiones. La interacción entre el genotipo, manejo cultural y fitosanitario con aspersión alternada con azoxistrobin con flutriafol; así como la fertilización aumentó el número de mazorcas de cacao en 48.5% y redujola incidencia de Moniliophthora rorerien 30.3%. |
