Abstract (es)

Avocado wilt complex (AWC) is the most important disease in this crop. AWC may be caused by different causal agents that induce similar symptoms. Accurate scales of disease development (SDD) and physiological changes may be of special importance for the diagnosis and management of AWC. The objective of this work was to design and calibrate a specific SDD for the most common causal agents associated with AWC in Colombia,
Phytophthora cinnamomi Rands and Verticillium dahliae Klebahn, and the hypoxia-anoxia disorder in both seedlings in net house and adult plants under field conditions. Furthermore, physiological responses to infection were determined. The disease was monitored under field and net house conditions. Shoot symptoms were recorded and quantification of inoculum
in infected soil and tissue was performed. The visual scale was described based on external symptoms and calibrated with the inocula values by regression analysis. In the net house, net photosynthesis, stomatal conductance, and transpiration were measured during the different stages of disease development. The three causal agents induced a progressive reduction of net photosynthesis, stomatal conductance, and transpiration. The designed scales can be a valuable tool for epidemiological use
and support in the diagnosis and management of AWC.

El complejo marchitez del aguacate (CMA) es la enfermedad más importante de este cultivo. El CMA puede ser causado por distintos agentes causales que inducen síntomas similares. Las escalas de desarrollo de la enfermedad (EDE) y los cambios fisiológicos pueden ser de gran importancia para el diagnóstico y manejo del CMA. El objetivo de este trabajo fue diseñar y calibrar EDE específicas para los agentes causales
más comunes asociados al CMA en Colombia, Phytophthora cinnamomi Rands y Verticillium dahliae Klebahn, y el desorden hipoxia-anoxia en plántulas de invernadero y plantas adultas en condiciones de campo. Además, se determinó la respuesta fisiológica durante la infección. La enfermedad se monitoreó en condiciones de campo e invernadero. Los síntomas de la parte aérea de la planta fueron registrados y se cuantificó el inóculo en el suelo y tejido afectado. Se describieron las escalas visuales
basadas en síntomas externos las cuales fueron calibradas con la cantidad de inóculo mediante análisis de regresión. En invernadero, se midieron la fotosíntesis neta, la conductancia estomática y la transpiración durante diferentes etapas del desarrollo de la enfermedad. Los tres agentes causales de enfermedad indujeron una reducción progresiva de la fotosíntesis neta, la conductancia estomática y la transpiración. Las escalas
diseñadas pueden ser una herramienta valiosa para su uso epidemiológico y de apoyo en el diagnóstico y manejo del AWC.
