In this disease, infection is visible on almost every part of the plant except the roots.
A Yellowness/greenness occurs at the edges of the leaves, while spots start occurring on their surfaces.
The wound is formed on the stem of the plant which is infected by this disease. Then a black-coloured gummy substance starts releasing from this wound.
On the string, brown spots become black spots which later go to the wound.
In bottle gourd seeds have medium-brown, dark spots.
