anthracnose of gourds

Anthracnose of gourds-Lesions tend to be dark and jagged. The lesions can be widespread on leaves, but the disease doesn’t seem to pose a problem in most years. The causal fungus may spread to fruit, but normally doesn’t cause marketable yield loss. In fact, light infections may develop in artistic patterns.
