Antifungal Activity of Propolis Extracts against Postharvest Pathogen <i>Phlyctema vagabunda</i>
<i>Phlyctema vagabunda</i> is one of the main postharvest pathogens in late-harvest apples in Chile. The control of this pathogen is mainly through synthetic fungicides or copper-based compounds; however, there are concerns about the residues of these products in food and the environment...

| description | <i>Phlyctema vagabunda</i> is one of the main postharvest pathogens in late-harvest apples in Chile. The control of this pathogen is mainly through synthetic fungicides or copper-based compounds; however, there are concerns about the residues of these products in food and the environment. Therefore, there is a need for seeking alternative control strategies, in which propolis, a resinous substance collected by bees with antimicrobial properties, could be an environmentally friendly and safe alternative to control for <i>P. vagabunda</i>. The aim of this study was to characterize and determine the pathogenicity of Chilean isolates of <i>P. vagabunda</i> and to evaluate the antifungal activity of propolis against <i>P. vagabunda</i> in vitro and in vivo conditions. The Chilean isolates were identified as <i>P. vagabunda</i> through morphological and molecular characterization. The concentrations of propolis of 0.5% and 0.05% significantly decreased the mycelial growth and germination of conidia by 88.5% and 100%, respectively. The incidence and severity of the disease in apples also decreased by 57.2% and 61.3%, respectively. The use of propolis extract could be a promising alternative for the control of <i>P. vagabunda</i> in apples. |
