The causative agent of this disease is Choanephora cucurbitarum, the fungus of the disease usually infects the upper part of the plant, flowers, leaves, new branches and fruits. In the initial stage, water-soaked areas develop on the leaf. The affected branch dries up and hangs. In severe infection, the fruits turn brown to black and a layer of fungus can be seen on the infected part.
