Anthracnose diseases of common landscape trees primarily affect stems and/or leaves. Flowering dogwood, American sycamore, green ash, and various maples are the most common landscape trees that fall victim to infection. If relative humidity or moisture is high, then twig dieback, blight, cankers and defoliation often result. Thus, anthracnose diseases are most devastating during the spring when rainfall is common and temperatures are cool (60º to 65º F). Long periods of cloudy or overcast skies greatly increase these diseases.
