First report of <i>Lasiodiplodia theobromae</i> causing spadix rot in <i>Anthurium andraeanum</i>

Abstract

Abstract Spadix rot was reported in Anthurium andraeanum cultivation farms in southern Thailand. The pathogen was identified as Lasiodiplodia theobromae , based on morphology and the nucleotide sequences of the internal transcribed spacer (ITS) and translation elongation factor 1‐α ( EF1 ‐α) genes. Pathogenicity test proved Koch's postulates, supporting that L. theobromae caused spadix rot in A. andraeanum . To our knowledge, this is the first report of L. theobromae causing spadix rot in A. andraeanum , in Thailand and elsewhere.
