Anthracnose is a common name for a group of fungal diseases that infect a wide variety of plants, including trees, shrubs, fruits, vegetables, and flowers. It is caused by several different fungi, most commonly in the genus Colletotrichum.
- Type of Infestation: Fungal Disease
- Common Name: Anthracnose
- Causal Organism: Gloeosporium ampelophagum
- Affected Parts Of the plant: Leaves, Shoot, Flowers and Berries
Environmental favorable factors for pests/Diseases:
- Temperature: The optimal temperature range for anthracnose development in grapes typically falls between 20-30°C (68-86°F). Within this range, 25-28°C (77-82°F) is often considered the most conducive for rapid disease progression.
- Humidity: High humidity is crucial: Anthracnose requires extended periods of leaf wetness for infection to occur. This means that high relative humidity (above 90%) or frequent rainfall events are important factors for disease development.
Symptoms of Pest/Disease:
- Dark, sunken spots or lesions on leaves, fruits, stems, or flowers
- Wilting, browning, and death of infected tissue
- Premature leaf drop
- Cankers on twigs and branches
