Abstract

Root and stem rot of rooted cuttings of young poinsettia plants were observed in a soil-less culture system in Buenos Aires Province, Argentina. Pythium aphanidermatum was identified as the causal agent of these symptoms. This is the first report of P. aphanidermatum affecting poinsettia in Argentina.
