First report of Lasiodiplodia theobromae causing spadix rot in Anthurium andraeanum
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 a (EF1 a) 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.
