Dogwood Anthracnose is a fungal disease that affects dogwood trees, and one of its most distinguishing visual characteristics is the presence of tan spots on the leaves with purple borders. These spots typically develop on the leaves and can also appear on the stems and flowers of the plant, causing significant damage. The tan color of the spots indicates areas where the leaf tissue has died, while the purple borders can help to differentiate it from other leaf diseases. This symptom is crucial for identifying the disease early, which helps in managing and controlling its spread effectively.

The other characteristics do not accurately represent Dogwood Anthracnose. For instance, thick stem growth is associated with various health factors in trees but is not a specific indicator of this disease. Bright yellow leaves can indicate general stress or nutrient deficiencies in plants but are not synonymous with Dogwood Anthracnose. Lastly, white fuzzy growths may suggest mold or mildew presence but do not reflect the specific symptoms of this fungal infection affecting dogwoods.
