Abstract
Kalanchoe blossfeldiana plants showing symptoms charcoal rot-like were collected in a greenhouse in Kermanshah province, West Iran. Based on morphology and phylogeny of DNA sequence data for the internal transcribed spacer (ITS) rDNA region, the isolated pathogen was identified as Macrophomina phaseolina. Pathogenicity tests in vivo were made on plants. Inoculated plants produced characteristic symptoms, and subsequent pathogen recovery confirmed pathogenicity. This study provides the first report of the occurrence of Macrophomina phaseolina on Kalanchoe blossfeldiana causing charcoal rot symptoms in Iran and the world.
