Choanephora cucurbitarum

Choanephora cucurbitarum is a fungal 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.
