Elsinoëe ampelina, Colletotrichum acutatum

Some table grape varieties are particularly susceptible. Symptoms occur on all aboveground parts of the vine, particularly on young tissues. Leaves develop numerous dark brown spots, 1/25 to 1/5 inch (1 to 5 mm) in diameter. As the centers fall out, lesions take on a “shot-hole” appearance. Severe infections curl and distort leaves.

Lesions on shoots are sunken and dark brown with grayish centers. On green berries, “bird’s-eye” spots are purplish brown or bleached with a dark edge. Berries remain firm, or crack and shrivel. The fungus overwinters in infected parts of the vine, and spores are dispersed by wind and rain splash in the spring. Anthracnose can be severe in rainy years.


Anthracnose is a southern disease that occurs sporadically in northern regions.
