The rot usually starts from the sepals from where it spreads to the fruit and peduncle. Inflorescences and leaf stalks exhibit brown-black necrosis. Infected fruits are usually smaller and taste bland (Picture 1).

The fungus overwinters on above-ground plant parts. During wet weather in the spring, the spores are ejected; they enter the plant tissue through stoma and sites of injury. More severe attacks occur in cold, wet weather and with sensitive varieties. Fruit rot can lead to significant harvest losses.
