First report of anthracnose of elephant foot yam caused by Colletotrichum siamense in India.

Abstract

Elephant foot yam (Amorphophallus paeoniifolius) showing pale to tan spots on leaves were observed in Pantnagar, Uttarakhand, India and in kitchen gardens in New Delhi, India. The causal pathogen was isolated and identified as Colletotrichum siamense based on morphological, molecular and pathogenicity analyses. The obtained sequences were deposited in GenBank as accession number KY887026 (ITS). This is thought to be the first report of leaf spot caused by C. siamense on A. paeoniifolius in India and globally.
