Black spot, grape anthracnose
Elsinoe ampelina
Anthracnose may cause significant economic loss by decreasing yield and quality. Anthracnose may reduce overall vigor of the vine. Specifically, anthracnose causes lesions on leaves, shoots, and fruit. Leaves develop circular brown tissue damage and shoots become black and brittle. Fruit may be shriveled, with purple, red, or black circles present. Pulp may drain from fruit lesions. Spores remain dormant in grape shoots until temperatures reach above 2°C and conditions are wet for a period of 24 hours or longer, at which point spores may spread by water from rain or irrigation.
