Fungal Diseases
Fungal diseases are a common problem for hostas, which can cause a variety of symptoms, including leaf spots and wilting. While there are a number of different fungal diseases that can affect hostas, some of the most common include anthracnose and Sclerotium blight.
Anthracnose is caused by a fungus called Colletotrichum, which can cause brown or black spots on leaves, stems, and flowers. These spots can eventually enlarge and merge, causing the leaves to turn yellow and drop prematurely. Anthracnose is most common during wet weather, and it can be spread by splashing water or by contact with infected plants.
Sclerotium blight is caused by a fungus called Sclerotium rolfsii cv delphinii, which can cause a white or gray mold to grow on stems, leaves, and soil. This mold can eventually cause the plant to wilt and die. Sclerotium blight is most common in warm, humid weather, and it can be spread by contact with infected soil or plant material.
