- Symptoms :

- These spots sometimes start near the veins which turn brown over a more or less limited portion.
- Affected tissues become necrotic, and can break down and fall off during very humid periods.
- Melon leaves dry out completely and remain attached to the plant, erect and curled (Figures 7 and 8).
- Symptoms progress very rapidly on leaves, plants and in plots.
