First report of Choanephora cucurbitarum, causing leaf blight of hyacinth bean in India.


In September 2014, leaf blight was observed on hyacinth bean (Lablab purpureus) in West Bengal, India, with a disease incidence of 5-20%. Symptoms included leaf discoloration with velvety sporulation of the pathogen on the leaf. Based on morphological characteristics, sequence analysis of the nuclear DNA internal transcribed spacer region and a pathogenicity test, the causal agent was identified as C. cucurbitarum. This is thought to be the first report of leaf blight disease of hyacinth bean caused by C. cucurbitarum in India.
