Choanephora cucurbitarum

The fungus Choanephora cucurbitarum is a plant pathogen that causes fruit and blossom rot of various cucurbits. It can also affect okra, snap bean, and southern pea, and may cause a stem and leaf rot of Withania somnifera. Recently Das et al. 2017 added few more patho-index on aubergine (Solanum melongena L.), teasle gourd (Momordica subangulata Blume subsp. renigera (G. Don) de Wilde, hyacinth bean (Lablab purpureus (L.) Sweet), green pea (Pisum sativum) from India. ( Wet weather, high temperature and high humidity favor disease development from inoculum that is typically soil-borne. Signs of infection on fruits or leaves include water-soaked, necrotic lesions, which progress rapidly under ideal conditions. As the fungus begins to produce spores, affected tissues become dark grey-brown and hairy as a result of the superficial sporangia.
