Bipolaris coicis causing adlay leaf blight in Iran

Abstract

During the summer of 2012, some leaves of Coix lacryma-jobi (adlay or Job's tears) with leaf spot symptoms were collected from surrounding rice fields of Amol, north Iran. Four single spore isolates were obtained from diseased adlay leaves and the pathogenicity of each isolate to adlay plants was confirmed by inoculation tests based on Koch's postulates. The pathogen was identified as Bipolaris coicis, based on both morphological characteristics and sequencing of the internal transcribed spacer region of the rDNA. This is the first report of Bipolaris coicis causing leaf blight on adlay in Iran. © 2013 Australasian Plant Pathology Society Inc.
