• The disease appears first as dark red spots on the berry. 
• Later, these spots are circular, sunken, ashy-gray and in late stages these spots are surrounded by a dark margin which gives it the “bird’s-eye rot” appearance.
• The spots vary in size from 1/4 inch in diameter to about half the fruit.
• The fungus also attacks shoots, tendrils, petioles, leaf veins, and fruit stems.
• Numerous spots sometimes occur on the young shoots.
• These spots may unite and girdle the stem, causing death of the tips.
• Spots on petioles and leaves cause them to curl or become distorted
• Seed-borne-infected vine, cuttings and air-borne conidia
• As dormant mycelium in the infected stem-cankers
• Warm wet weather
• Low lying and badly drained soils.

Management

• Removal of infected twigs
